Subject: ath10k: Wait until copy complete is actually done before completing

On wcn3990 we have "per_ce_irq = true".  That makes the
ath10k_ce_interrupt_summary() function always return 0xfff. The
ath10k_ce_per_engine_service_any() function will see this and think
that _all_ copy engines have an interrupt.  Without checking, the
ath10k_ce_per_engine_service() assumes that if it's called that the
"copy complete" (cc) interrupt fired.  This combination seems bad.

Let's add a check to make sure that the "copy complete" interrupt
actually fired in ath10k_ce_per_engine_service().

This might fix a hard-to-reproduce failure where it appears that the
copy complete handlers run before the copy is really complete.
Specifically a symptom was that we were seeing this on a Qualcomm
sc7180 board:
  arm-smmu 15000000.iommu: Unhandled context fault:
  fsr=0x402, iova=0x7fdd45780, fsynr=0x30003, cbfrsynra=0xc1, cb=10

Even on platforms that don't have wcn3990 this still seems like it
would be a sane thing to do.  Specifically the current IRQ handler
comments indicate that there might be other misc interrupt sources
firing that need to be cleared.  If one of those sources was the one
that caused the IRQ handler to be called it would also be important to
double-check that the interrupt we cared about actually fired.

Subject: ath10k: fix retry packets update in station dump

When tx status enabled, retry count is updated from tx completion status.
which is not working as expected due to firmware limitation where
firmware can not provide per MSDU rate statistics from tx completion
status. Due to this tx retry count is always 0 in station dump.

Fix this issue by updating the retry packet count from per peer
statistics. This patch will not break on SDIO devices since, this retry
count is already updating from peer statistics for SDIO devices.

Subject: ath10k: provide survey info as accumulated data

It is expected that the returned counters by .get_survey are monotonic
increasing. But the data from ath10k gets reset to zero regularly. Channel
active/busy time are then showing incorrect values (less than previous or
sometimes zero) for the currently active channel during successive survey
dump commands.

example:

  $ iw dev wlan0 survey dump
  Survey data from wlan0
  	frequency:                      5180 MHz [in use]
  	channel active time:            54995 ms
  	channel busy time:              432 ms
  	channel receive time:           0 ms
  	channel transmit time:          59 ms
  ...

  $ iw dev wlan0 survey dump
  Survey data from wlan0
  	frequency:                      5180 MHz [in use]
  	channel active time:            32592 ms
  	channel busy time:              254 ms
  	channel receive time:           0 ms
  	channel transmit time:          0 ms
  ...

The correct way to handle this is to use the non-clearing
WMI_BSS_SURVEY_REQ_TYPE_READ wmi_bss_survey_req_type. The firmware will
then accumulate the survey data and handle wrap arounds.

Subject: ath10k: pci: fix memcpy size of bmi response

A compromized ath10k peripheral is able to control the size argument
of memcpy in ath10k_pci_hif_exchange_bmi_msg.

The min result from previous line is not used as the size argument
for memcpy. Instead, xfer.resp_len comes from untrusted stream dma
input. The value comes from "nbytes" in ath10k_pci_bmi_recv_data,
which is set inside _ath10k_ce_completed_recv_next_nolock with the line

nbytes = __le16_to_cpu(sdesc.nbytes);

sdesc is a stream dma region which device can write to.

Subject: ath11k: create a common function to request all firmware files

To avoid duplicating the logic how the full firmware path is created create a
common function ath11k_core_firmware_request() and convert also qmi.c to use it.

Also remove a useless info print, it's more like a debug message anyway.

No functional changes. Compile tested only.

Subject: ath11k: don't use defines for hw specific firmware directories

The downside of using defines in struct ath11k_hw_params.fw.dir is that it's
easy to get it wrong as the full path is not visible. So drop the use of
defines and instead create the patch runtime using a static inline function
ath11k_core_create_firmware_path(). Hopefully this reduces the chances of using
incorrect firmware path.

No functional changes. Compile tested only.

 ath11k_core_create_firmware_path()

Use the helper added in previous comment to create the full path, instead of doing it manually.

No functional changes. Compile tested only.

Subject: ath9k: Check the return value of pcie_capability_read_*()

On failure pcie_capability_read_dword() sets it's last parameter, val
to 0. However, with Patch 14/14, it is possible that val is set to ~0 on
failure. This would introduce a bug because (x & x) == (~0 & x).

This bug can be avoided without changing the function's behaviour if the
return value of pcie_capability_read_dword is checked to confirm success.

Check the return value of pcie_capability_read_dword() to ensure success.

Subject: ath10k: check idx validity in __ath10k_htt_rx_ring_fill_n()

The idx in __ath10k_htt_rx_ring_fill_n function lives in
consistent dma region writable by the device. Malfunctional
or malicious device could manipulate such idx to have a OOB
write. Either by
    htt->rx_ring.netbufs_ring[idx] = skb;
or by
    ath10k_htt_set_paddrs_ring(htt, paddr, idx);

The idx can also be negative as it's signed, giving a large
memory space to write to.

It's possibly exploitable by corruptting a legit pointer with
a skb pointer. And then fill skb with payload as rougue object.

Part of the log here. Sometimes it appears as UAF when writing
to a freed memory by chance.

Reduces attack surface on kernel devs opening the links for MITM

Deterministic algorithm:
For each file:
  If not .svg:
    For each line:
      If doesn't contain `\bxmlns\b`:

Subject: wcn36xx: Fix multiple AMPDU sessions support

Several AMPDU sessions can be started, e.g. for different TIDs.
Currently the driver does not take care of the session ID when
requesting block-ack (statically set to 0), which leads to never
block-acked packet with sessions other than 0.

Fix this by saving the session id when creating the ba session and
use it in subsequent ba operations.

This issue can be reproduced with iperf in two steps (tid 0 strem
then tid 6 stream).

1.0 iperf -s                                # wcn36xx side
1.1 iperf -c ${IP_ADDR}                     # host side

Then

2.0 iperf -s -u -S 0xC0                     # wcn36xx side
2.1 iperf -c ${IP_ADDR} -u -S 0xC0 -l 2000  # host side

Subject: wcn36xx: Add TX ack support

The controller is capable of reporting TX indication which can be used
to report TX ack when IEEE80211_TX_CTL_REQ_TX_STATUS is set.
The support was only partially implemented.

The firmware can be configured for reporting event when a packet is
acked, without specifying which packet though. In order to send a
packet flagged with TX status callback, we need to stop the queue,
submit the packet and wait for the firmware ack event. Then the queue
can be restarted and mac80211 status callback called.

In case the packet is not acked, no ack event will be received,
therefore a timeout mechanism is introduced to restart the queue
and call the status cb in case no event is received after a 100ms.

Subject: wcn36xx: Increase number of TX retries

Increase the short/long retry limit to 15 in order to impove TX
robustness in noisy/busy environment. 15 is the default value
defined in the downstream driver. Observed number of ack timeout
is reduced with this change.

Subject: wcn36xx: Fix TX data path

This patch contains the following fixes:

- Use correct queue for submitting QoS packet. The queue id to use
is a one-to-one mapping with the TID.

- Don't encrypt a frame with IEEE80211_TX_INTFL_DONT_ENCRYPT flag.

- Use the 'special queue' for null packets, preventing the firmware
to submit it as AMPDU.

Subject: wcn36xx: Use sequence number allocated by mac80211

Instead of using the firmware generated sequence number, use the one
already allocated by the mac80211 layer. This allows better control
of the sequence numbers and avoid to rely on same sequence for Data,
QOS Data and QOS Null Data packets.

Subject: ath: drop unnecessary list_empty

list_for_each_entry{_safe} is able to handle an empty list.
The only effect of avoiding the loop is not initializing the
index variable.
Drop list_empty tests in cases where these variables are not
used.

Note that list_for_each_entry{_safe} is defined in terms of
list_first_entry, which indicates that it should not be used on an
empty list.  But in list_for_each_entry{_safe}, the element obtained
by list_first_entry is not really accessed, only the address of its
list_head field is compared to the address of the list head, so the
list_first_entry is safe.

The semantic patch that makes this change for the list_for_each_entry
case is as follows: (http://coccinelle.lip6.fr/)

<smpl>
@@
expression x,e;
statement S;
identifier i;
@@

-if (!(list_empty(x)))
   list_for_each_entry(i,x,...) S

Subject: ath5k: Replace HTTP links with HTTPS ones

Rationale:
Reduces attack surface on kernel devs opening the links for MITM
as HTTPS traffic is much harder to manipulate.

Deterministic algorithm:
For each file:
  If not .svg:
    For each line:
      If doesn't contain `\bxmlns\b`:
        For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`:
	  If neither `\bgnu\.org/license`, nor `\bmozilla\.org/MPL\b`:
            If both the HTTP and HTTPS versions
            return 200 OK and serve the same content:
              Replace HTTP with HTTPS.

Subject: ath10k: start recovery process when payload length exceeds max htc
 length for sdio

When simulate random transfer fail for sdio write and read, it happened
"payload length exceeds max htc length" and recovery later sometimes.

Test steps:
1. Add config and update kernel:
CONFIG_FAIL_MMC_REQUEST=y
CONFIG_FAULT_INJECTION=y
CONFIG_FAULT_INJECTION_DEBUG_FS=y

2. Run simulate fail:
cd /sys/kernel/debug/mmc1/fail_mmc_request
echo 10 > probability
echo 10 > times # repeat until hitting issues

3. It happened payload length exceeds max htc length.
[  199.935506] ath10k_sdio mmc1:0001:1: payload length 57005 exceeds max htc length: 4088
....
[  264.990191] ath10k_sdio mmc1:0001:1: payload length 57005 exceeds max htc length: 4088

4. after some time, such as 60 seconds, it start recovery which triggered
by wmi command timeout for periodic scan.
[  269.229232] ieee80211 phy0: Hardware restart was requested
[  269.734693] ath10k_sdio mmc1:0001:1: device successfully recovered

The simulate fail of sdio is not a real sdio transter fail, it only
set an error status in mmc_should_fail_request after the transfer end,
actually the transfer is success, then sdio_io_rw_ext_helper will
return error status and stop transfer the left data. For example,
the really RX len is 286 bytes, then it will split to 2 blocks in
sdio_io_rw_ext_helper, one is 256 bytes, left is 30 bytes, if the
first 256 bytes get an error status by mmc_should_fail_request,then
the left 30 bytes will not read in this RX operation. Then when the
next RX arrive, the left 30 bytes will be considered as the header
of the read, the top 4 bytes of the 30 bytes will be considered as
lookaheads, but actually the 4 bytes is not the lookaheads, so the len
from this lookaheads is not correct, it exceeds max htc length 4088
sometimes. When happened exceeds, the buffer chain is not matched between
firmware and ath10k, then it need to start recovery ASAP. Recently then
recovery will be started by wmi command timeout, but it will be long time
later, for example, it is 60+ seconds later from the periodic scan, if
it does not have periodic scan, it will be longer.

Start recovery when it happened "payload length exceeds max htc length"
will be reasonable.

This patch only effect sdio chips.

Tested with QCA6174 SDIO with firmware WLAN.RMH.4.4.1-00029.

Subject: ath10k: add wmi service peer stat info for wmi tlv

ath10k_sta_statistics is used to report info for iw wlan0 link,
it check ath10k_peer_stats_enabled, and ath10k_peer_stats_enabled
check WMI_SERVICE_PEER_STATS bit of ar->wmi.svc_map. SVCMAP() for
WMI_SERVICE_PEER_STATS was defined only for wmi_10x_svc_map and
wmi_10_4_svc_map interfaces, it missed in wmi_tlv_svc_map, so it is
not usable for iw wlan0 link for wmi tlv interface.

If firmware report WMI_TLV_SERVICE_PEER_STATS_INFO for wmi tlv, then
enable the WMI_SERVICE_PEER_STATS bit in ath10k, and then it pass check
in ath10k_peer_stats_enabled and ath10k_sta_statistics pass check.

Subject: ath10k: remove return for NL80211_STA_INFO_TX_BITRATE

ath10k_sta_statistics is used to report many info to iw wlan0 link,
if it return for empty legacy and nss of arsta->txrate, then the other
stats after it will not be set.

It has 4 bit to set after the return:
NL80211_STA_INFO_TX_FAILED
NL80211_STA_INFO_RX_BITRATE
NL80211_STA_INFO_TX_BITRATE
NL80211_STA_INFO_TX_RETRIES

This patch not effect the info of above 4 bit for all hardware, reason
as below:

NL80211_STA_INFO_TX_FAILED is only for htt.disable_tx_comp is true, it
is for QCA6174 SDIO.

NL80211_STA_INFO_RX_BITRATE and NL80211_STA_INFO_TX_BITRATE are both
set in ath10k_mac_sta_get_peer_stats_info, it is only enabled for chips
which supports_peer_stats_info is true in hw_params, recently only for
QCA6174 SDIO, NL80211_STA_INFO_TX_BITRATE is set again in function
ath10k_mac_sta_get_peer_stats_info because the value which parsed from
arsta->tx_rate_code and arsta->tx_bitrate_kbps is correct for QCA6174
SDIO and PCIe, and the value arsta->txrate is not correct for QCA6174
SDIO and PCIe, so it need to set again with the correct value.

NL80211_STA_INFO_TX_RETRIES is use value of arsta->tx_retries, it is set
in ath10k_update_per_peer_tx_stats, which accumulate the retry_pkts in
HTT message from firmware, if the chips not support this feature, then
it is always 0 after accumulate, then iw wlan0 station dump always show
0 for retry count. If not set NL80211_STA_INFO_TX_RETRIES here, then it
is still 0, so the result is same, then set NL80211_STA_INFO_TX_RETRIES
has no effect.

Subject: ath10k: enable supports_peer_stats_info for QCA6174 PCI devices

When using QCA6174 PCI devices working in station mode, after connected
to AP, tx bitrate is always '1.0 MBit/s' in output of command 'iw wlan0
station dump'. (QCA6174 SDIO devices are working fine.)

After this patch, it show correct bitrate:

Subject: ath10k: correct the array index from mcs index for HT mode for
 QCA6174

The mcs index of HT mode is 0 to 31, please refer http://mcsindex.com/.
Its spatial stream(Nss) number is from 1 to 4, mcs index is 0~7 for
Nss=1, 8~15 for Nss=2, 16~23 for Nss=3 and 24~31 is for Nss=4.

The mcs is reported from firmware in wmi_tlv_peer_stats_info of
event WMI_TLV_PEER_STATS_INFO_EVENTID, its range is from 0~15 for
QCA6174 SDIO and PCIe. It is for both Nss=1 and Nss=2, and it has 2
rate table supported_ht_mcs_rate_nss1 and supported_ht_mcs_rate_nss2
in ath10k, they are for Nss=1 and Nss=2, each table has 8 rates.

It need to find the matched row number with the mcs index, for example,
mcs index is 2, it is <=7, so it is Nss=1, and match row 2 in table of
Nss=1. If mcs index is 12, it is >= 8 and <= 15, so it is Nss=2, it
match row 4(12-8) in table of Nss=2. If mcs index is >=16, it is for
Nss=3/4, it need to add rate table, so it is not support in current
ath10k.

This patch is to find the row number in rate table of Nss=1 or Nss=2
with the mcs index reported from firmware.

This patch only effect the chips which supports_peer_stats_info of its
hw_params is true, it is true only for QCA6174 currently.

With only IPQ8074 supported ath11k was only usable on Qualcomm architectures.
But now that we are adding QCA6390 PCI support to ath11k that's not the case
anymore and it can be used on any architecture supporting PCI. So remove the
dependency on ARCH_QCOM. After that there is also no need to depend on
COMPILE_TEST.

Subject: ath11k: add simple PCI client driver for QCA6390 chipset

QCA6390 is a PCI based 11ax chipset, split AHB into own kernel module
ath11k_ahb.ko and add ath11k_pci.ko for PCI devices.

Tested-on: QCA6390 hw2.0 PCI WLAN.HST.1.0.1-01740-QCAHSTSWPLZ_V2_TO_X86-1
Tested-on: IPQ8074 hw2.0 AHB WLAN.HK.2.1.0.1-01238-QCAHKSWPL_SILICONZ-2

needs location of firmware directory and that's delivered via hw_params.

Subject: ath11k: register MHI controller device for QCA6390
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Modem Host Interface (MHI) is a communication protocol to communicate with
external Qualcomm modems and Wi-Fi chipsets over high speed peripheral buses.
Even though MHI doesn’t dictate underlying physical layer, protocol and MHI
stack is structured for PCI based devices.

Register directly with MHI subsystem as a MHI device driver for firmware
download to QCA6390.

Subject: ath11k: use remoteproc only with AHB devices

QCA6390 and other PCI devices use MHI based firmware loading and do not use
remoteproc, so enable it only for AHB devices.

Tested-on: QCA6390 hw2.0 PCI WLAN.HST.1.0.1-01740-QCAHSTSWPLZ_V2_TO_X86-1
Tested-on: IPQ8074 hw2.0 AHB WLAN.HK.2.1.0.1-01238-QCAHKSWPL_SILICONZ-2

Subject: ath11k: add support for m3 firmware

PCI devices like QCA6390 have a separate firmware image for the m3
micro-controller. Add support to load the firmware using m3.bin file.

Tested-on: QCA6390 hw2.0 PCI WLAN.HST.1.0.1-01740-QCAHSTSWPLZ_V2_TO_X86-1
Tested-on: IPQ8074 hw2.0 AHB WLAN.HK.2.1.0.1-01238-QCAHKSWPL_SILICONZ-2

Subject: ath11k: add board file support for PCI devices

PCI devices like QCA6390 load the board file differently, add support for that
and the method is chosen using bus_params variables.

Add support to create board name for different targets.  This board name is
used to parse the board data from board-2.bin for ahb/pci based targets.

As struct target_mem_chunk::vaddr was changed from 'u32' to 'u32 *' in
ath11k_qmi_assign_target_mem_chunk() vaddr assignments were changed to NULL to
avoid a compilation warning. IPQ8074 does not use the vaddr field for anything
so that change does not affect functionality.

At the moment this only supports board files with BIN type. Support for ELF
type, which seems to be more popular on QCA6390 devices, needs to be added later.

Tested-on: QCA6390 hw2.0 PCI WLAN.HST.1.0.1-01740-QCAHSTSWPLZ_V2_TO_X86-1
Tested-on: IPQ8074 hw2.0 AHB WLAN.HK.2.1.0.1-01238-QCAHKSWPL_SILICONZ-2

Subject: ath11k: fill appropriate QMI service instance id for QCA6390

QMI service instance id is used for qmi service lookup, IPQ8074 and QCA6390
uses different instance id for service lookup.  Fill appropriate QMI service
instance id for respective targets.

Tested-on: QCA6390 hw2.0 PCI WLAN.HST.1.0.1-01740-QCAHSTSWPLZ_V2_TO_X86-1
Tested-on: IPQ8074 hw2.0 AHB WLAN.HK.2.1.0.1-01238-QCAHKSWPL_SILICONZ-2

Subject: ath11k: allocate smaller chunks of memory for firmware

On x86 it's sometimes difficult to allocate a large contigous DMA
memory, so instead allocate blocks of small chunk memory.

In ath11k_qmi_msg_mem_request_cb() the error handling was cleaned up to avoid
an unused variable warning. Also changed the test from (ret < 0) to just (ret)
as the functions don't return any positive values.

Subject: ath11k: fix memory OOB access in qmi_decode

The decoded_size is wrongly assigned in ath11k_qmi_msg_handlers and it results
in out of boundary access in qmi_decode. The correct decoded_size should be
calculated from the related ind_msg structure.

This issue is exposed with QCA6390 because it needs 11 small memory chunks
which are stored in qmi_wlanfw_request_mem_ind_msg_v01 and hence the
decoded_size exceeds the wrongly assigend decoded_size.

Subject: ath11k: enable internal sleep clock

On x86 and other non-qcom platforms, host needs to explicitly tell the firmware
to use the internal sleep clock. Some QCA6390 modules have OTP burnt with
external sleep clock selected, and these modules can't work expectedly unless
firmware selects internal sleep clock.

Add a field to hw_params to support this difference.

Tested-on: QCA6390 hw2.0 PCI WLAN.HST.1.0.1-01740-QCAHSTSWPLZ_V2_TO_X86-1
Tested-on: IPQ8074 hw2.0 AHB WLAN.HK.2.1.0.1-01238-QCAHKSWPL_SILICONZ-2

Subject: ath11k: hal: create hw_srng_config dynamically

On QCA6390 reg_start and reg_size values are different from IPQ8074 so we need
to change the values runtime. As we can't modify a static const variable
hw_srng_config directly, instead use it as a template, copy it and modify the
copy with correct values.

Tested-on: QCA6390 hw2.0 PCI WLAN.HST.1.0.1-01740-QCAHSTSWPLZ_V2_TO_X86-1
Tested-on: IPQ8074 hw2.0 AHB WLAN.HK.2.1.0.1-01238-QCAHKSWPL_SILICONZ-2

Subject: ath6kl: prevent potential array overflow in ath6kl_add_new_sta()

The value for "aid" comes from skb->data so Smatch marks it as
untrusted.  If it's invalid then it can result in an out of bounds array
access in ath6kl_add_new_sta().

Subject: ath9k: add NL80211_EXT_FEATURE_CAN_REPLACE_PTK0 support

The ath9k driver was so far only able to rekey PTK0 keys correctly due
to the best effort queue flush added with commit 62872a9b9a10
("mac80211: Fix PTK rekey freezes and clear text leak").

Add the needed queue flush and set NL80211_EXT_FEATURE_CAN_REPLACE_PTK0
to tell mac80211 that the driver can now rekey PTK0 keys correctly and
no longer needs the best effort flush.

Effectively this prevents mac80211 to warn when rekeying a PTK0 key
only.

The value of "htc_hdr->endpoint_id" comes from skb->data so Smatch marks
it as untrusted so we have to check it before using it as an array
offset.

This is similar to a bug that syzkaller found in commit e4ff08a4d727
("ath9k: Fix use-after-free Write in ath9k_htc_rx_msg") so it is
probably a real issue.

Subject: ath10k: move enable_pll_clk call to ath10k_core_start()

There's no reason to have call for enable_pll_clk in ath10k_bmi_start(), move
it to ath10k_core_start() instead. This way it's possible to call
ath10k_bmi_start() from sdio.c during firmware dump creation. And also the
function call is more visible when it's in core.c.

No functional changes, compile tested only.

Subject: ath11k: hal: create register values dynamically

QCA6390 has different register offset compared to IPQ8074, so need to
attach the register offset dynamically based on hw_params.

Tested-on: QCA6390 hw2.0 PCI WLAN.HST.1.0.1-01740-QCAHSTSWPLZ_V2_TO_X86-1
Tested-on: IPQ8074 hw2.0 AHB WLAN.HK.2.1.0.1-01238-QCAHKSWPL_SILICONZ-2

Subject: ath11k: hal: cleanup dynamic register macros

Now some of the HAL register macros access ab variable in a hidden way, make ab
variable visible in the macro by adding it as an argument.

This is done in a separate patch to keep the patches simple. No functional changes.

Tested-on: QCA6390 hw2.0 PCI WLAN.HST.1.0.1-01740-QCAHSTSWPLZ_V2_TO_X86-1
Tested-on: IPQ8074 hw2.0 AHB WLAN.HK.2.1.0.1-01238-QCAHKSWPL_SILICONZ-2

From e3396b8bddd2ea822f9390f1ba49c22d769a7534 Mon Sep 17 00:00:00 2001
From: Carl Huang <cjhuang@codeaurora.org>

Subject: ath11k: ce: support different CE configurations

QCA6390 uses only 9 Copy Engines while IPQ8074 may use 12, make it possible to
change CE configuration dynamically via hw_params.

The defines for host_ce_config_wlan and CE_COUNT are temporary solutions, they
will be removed in the following patches to keep things simple.

Tested-on: QCA6390 hw2.0 PCI WLAN.HST.1.0.1-01740-QCAHSTSWPLZ_V2_TO_X86-1
Tested-on: IPQ8074 hw2.0 AHB WLAN.HK.2.1.0.1-01238-QCAHKSWPL_SILICONZ-2

Subject: ath11k: ce: remove host_ce_config_wlan macro

This macro is evil as it's accesses ab variable in a hidden way. It's better
for readibility to access ab->hw_params.host_ce_config directly.

This is done in a separate patch to keep the patches simple. No functional changes.

Subject: ath11k: hal: assign msi_addr and msi_data to srng

QCA6390 uses MSI interrupt so it needs msi_addr and msi_data
to generate interrupt.

QCA6390 has very different wmi config parameters compared to IPQ8074,
so use different function to initialize wmi init config parameters.

Subject: ath11k: wmi: put hardware to DBS mode

For QCA6390, host puts hardware to Dual Band Simultaneous (DBS) mode by default
so both 2G and 5G bands can be used. Otherwise only the 5G band can be used.
QCA6390 doesn't provide band_to_mac configuration and firmware will do the
band_to_mac map.

Tested-on: QCA6390 hw2.0 PCI WLAN.HST.1.0.1-01740-QCAHSTSWPLZ_V2_TO_X86-1
Tested-on: IPQ8074 hw2.0 AHB WLAN.HK.2.1.0.1-01238-QCAHKSWPL_SILICONZ-2

Subject: ath11k: don't initialize rxdma1 related ring

For QCA6390, it has 2 lmacs and thus 2 rxdmas. However, each rxdma has rxdma0
only, and doesn't have rxdma1. So for QCA6390, don't initialize rxdma1 related
rings such as rx_mon_buf_ring, rx_mon_dst_ring and rx_mon_desc_ring.

Tested-on: QCA6390 hw2.0 PCI WLAN.HST.1.0.1-01740-QCAHSTSWPLZ_V2_TO_X86-1
Tested-on: IPQ8074 hw2.0 AHB WLAN.HK.2.1.0.1-01238-QCAHKSWPL_SILICONZ-2

Subject: ath11k: setup QCA6390 rings for both rxdmas

For QCA6390, only one pdev is created and this pdev manages both lmacs, thus
both rxdmas. So host needs to initialize all rxdma related rings for one pdev.

Another difference is for QCA6390, host fills rxbuf to firmware and firmware
further fills the rxbuf to rxbuf ring for each rxdma.

Tested-on: QCA6390 hw2.0 PCI WLAN.HST.1.0.1-01740-QCAHSTSWPLZ_V2_TO_X86-1
Tested-on: IPQ8074 hw2.0 AHB WLAN.HK.2.1.0.1-01238-QCAHKSWPL_SILICONZ-2

Subject: ath11k: refine the phy_id check in ath11k_reg_chan_list_event

For QCA6390, it processes the reg chan list event only for phy0,
and it goes to fallback if the phy_id is not valid. For a valid
phy_id but not 0, just discard the event.

Tested-on: QCA6390 hw2.0 PCI WLAN.HST.1.0.1-01740-QCAHSTSWPLZ_V2_TO_X86-1
Tested-on: IPQ8074 hw2.0 AHB WLAN.HK.2.1.0.1-01238-QCAHKSWPL_SILICONZ-2

Subject: ath11k: assign correct search flag and type for QCA6390

QCA6390 doesn't enable V2 map and ummap event, so the addr search
flags and type is different from IPQ8074. Assign correct search flags
and type for QCA6390.

Without this change, ping sometimes fails. With this change, now ping
is always successful.

Tested-on: QCA6390 hw2.0 PCI WLAN.HST.1.0.1-01740-QCAHSTSWPLZ_V2_TO_X86-1
Tested-on: IPQ8074 hw2.0 AHB WLAN.HK.2.1.0.1-01238-QCAHKSWPL_SILICONZ-2

Subject: ath11k: process both lmac rings for QCA6390

For QCA6390, the num_radios is 1 but it needs to process 2 lmac rings.
So use NUM_RXDMA_PER_PDEV to do another loop.

Subject: ath11k: use TCL_DATA_RING_0 for QCA6390

For QCA6390, wbm2sw1 is used for other purpose rather than
tx completion ring. So use TCL_DATA_RING 0 only for QCA6390.

Add MISC_CAPS_TCL_0_ONLY to control it.

Subject: ath11k: reset MHI during power down and power up

For QCA6390, normal power up and power down can't bring MHI
to a workable state. This happens especially in warm reboot
and rmmod and insmod. Host needs to write a few registers to
bring MHI to normal state.

Subject: ath10k: Register shutdown handler

As a part of device shutdown the smmu driver will be
stopped and henceforth any IOVA address translation
will not be done. The wlan driver, being one of the
smmu driver consumer, should stop all the dma related
activity as a part of shutdown, and thereby ensuring
that no dma activity is done once the smmu driver
shuts down.

During the device shutdown, the smmu calls shutdown
for all its consumers in order to indicate them to
stop all their dma activities.

Register the shutdown handler to stop the wlan
driver and avoid any dma operations.

When STBC is enabled, NSTS_SU value need to be accounted for VHT NSS
calculation for SU case.

Without this fix, 1SS + STBC enabled case was reported wrongly as 2SS
in radiotap header on monitor mode capture.
