We're now calling intel_pipe_config_compare(..., true) uncoditionally
which means we're always going clobber the calculated M/N values with
the old values if the fuzzy M/N check passes. That causes problems
because the fuzzy check allows for a huge difference in the values.
I'm actually tempted to just make the M/N checks exact, but that might
prevent fastboot from kicking in when people want it. So for now let's
overwrite the computed values with the old values only if decide to skip
the modeset.

UFS runtime suspend can be triggered after pm_runtime_enable() is invoked
in ufshcd_pltfrm_init(). However if the first runtime suspend is triggered
before binding ufs_hba structure to ufs device structure via
platform_set_drvdata(), then UFS runtime suspend will be no longer
triggered in the future because its dev->power.runtime_error was set in the
first triggering and does not have any chance to be cleared.
To be more clear, dev->power.runtime_error is set if hba is NULL in
ufshcd_runtime_suspend() which returns -EINVAL to rpm_callback() where
dev->power.runtime_error is set as -EINVAL. In this case, any future
rpm_suspend() for UFS device fails because rpm_check_suspend_allowed()
fails due to non-zero
dev->power.runtime_error.
To resolve this issue, make sure the first UFS runtime suspend get valid
"hba" in ufshcd_runtime_suspend(): Enable UFS runtime PM only after hba is
successfully bound to UFS device structure.

- Regression fixes for D_CAN on am355x
- i.MX6SX cpuidle fix to deal with wakeup latency (dropped uart

- DT fixes for some DRA7 variants that don't share the superset of

Currently after setting tap0 link up, the tun code wakes tx/rx waited
queues up in tun_net_open() when .ndo_open() is called, however the
IFF_UP flag has not been set yet. If there's already a wait queue, it
would fail to transmit when checking the IFF_UP flag in tun_sendmsg().
Then the saving vhost_poll_start() will add the wq into wqh until it
is waken up again. Although this works when IFF_UP flag has been set
when tun_chr_poll detects; this is not true if IFF_UP flag has not
been set at that time. Sadly the latter case is a fatal error, as
the wq will never be waken up in future unless later manually
setting link up on purpose.
Fix this by moving the wakeup process into the NETDEV_UP event
notifying process, this makes sure IFF_UP has been set before all
waited queues been waken up.

Some transceivers may comply with SFF-8472 even though they do not
implement the Digital Diagnostic Monitoring (DDM) interface described in
the spec. The existence of such area is specified by the 6th bit of byte
92, set to 1 if implemented.
Currently, without checking this bit, bnx2x fails trying to read sfp
module's EEPROM with the follow message:
ethtool -m enP5p1s0f1
Cannot get Module EEPROM data: Input/output error
Because it fails to read the additional 256 bytes in which it is assumed
to exist the DDM data.
This issue was noticed using a Mellanox Passive DAC PN 01FT738. The EEPROM
data was confirmed by Mellanox as correct and similar to other Passive
DACs from other manufacturers.

USB 3.2 capability in a host can be detected from the
xHCI Supported Protocol Capability major and minor revision fields.
If major is 0x3 and minor 0x20 then the host is USB 3.2 capable.
For USB 3.2 capable hosts set the root hub lane count to 2.
The Major Revision and Minor Revision fields contain a BCD version number.
The value of the Major Revision field is JJh and the value of the Minor

A USB3 device needs to be reset and re-enumarated if the port it
connects to goes to a error state, with link state inactive.
There is no use in trying to recover failed transactions by resetting
endpoints at this stage. Tests show that in rare cases, after multiple
endpoint resets of a roothub port the whole host controller might stop
completely.
Several retries to recover from transaction error can happen as
it can take a long time before the hub thread discovers the USB3
port error and inactive link.
We can't reliably detect the port error from slot or endpoint context
due to a limitation in xhci, see xhci specs section 4.8.3:
"There are several cases where the EP State field in the Output
Endpoint Context may not reflect the current state of an endpoint"
and
"Software should maintain an accurate value for EP State, by tracking it
with an internal variable that is driven by Events and Doorbell accesses"
Same appears to be true for slot state.
set a flag to the corresponding slot if a USB3 roothub port link goes
inactive to prevent both queueing new URBs and resetting endpoints.

Stopping external metadata arrays during resync/recovery causes
retries, loop of interrupting and starting reconstruction, until it
hit at good moment to stop completely. While these retries
curr_mark_cnt can be small- especially on HDD drives, so subtraction
result can be smaller than 0. However it is casted to uint without
checking. As a result of it the status bar in /proc/mdstat while stopping
is strange (it jumps between 0% and 99%).
The real problem occurs here after commit 72deb455b5ec ("block: remove
CONFIG_LBDAF"). Sector_div() macro has been changed, now the
divisor is casted to uint32. For db = -8 the divisior(db/32-1) becomes 0.
Check if db value can be really counted and replace these macro by
div64_u64() inline.

Processing of SDIO IRQs must obviously be prevented while the card is
system suspended, otherwise we may end up trying to communicate with an
uninitialized SDIO card.
Reports throughout the years shows that this is not only a theoretical
problem, but a real issue. So, let's finally fix this problem, by keeping
track of the state for the card and bail out before processing the SDIO
IRQ, in case the card is suspended.

The O2Micro controller only supports tuning at 4-bits. So the host driver
needs to change the bus width while tuning and then set it back when done.
There was a bug in the original implementation in that mmc->ios.bus_width
also wasn't updated. Thus setting the incorrect blocksize in
sdhci_send_tuning which results in a tuning failure.

When Broadcom SDIO cards are idled they go to sleep and a whole
separate subsystem takes over their SDIO communication. This is the
Always-On-Subsystem (AOS) and it can't handle tuning requests.
Specifically, as tested on rk3288-veyron-minnie (which reports having
BCM4354/1 in dmesg), if I force a retune in brcmf_sdio_kso_control()
when "on = 1" (aka we're transition from sleep to wake) by whacking:
bus->sdiodev->func1->card->host->need_retune = 1
...then I can often see tuning fail. In this case dw_mmc reports "All
phases bad!"). Note that I don't get 100% failure, presumably because
sometimes the card itself has already transitioned away from the AOS
itself by the time we try to wake it up. If I force retuning when "on
= 0" (AKA force retuning right before sending the command to go to
sleep) then retuning is always OK.
NOTE: we need _both_ this patch and the patch to avoid triggering
tuning due to CRC errors in the sleep/wake transition, AKA ("brcmfmac:
sdio: Disable auto-tuning around commands expected to fail"). Though
both patches handle issues with Broadcom's AOS, the problems are
distinct:
1. We want to defer (but not ignore) asynchronous (like
timer-requested) tuning requests till the card is awake. However,
we want to ignore CRC errors during the transition, we don't want
to queue deferred tuning request.
2. You could imagine that the AOS could implement retuning but we
could still get errors while transitioning in and out of the AOS.
Similarly you could imagine a seamless transition into and out of
the AOS (with no CRC errors) even if the AOS couldn't handle
tuning.
ALSO NOTE: presumably there is never a desperate need to retune in
order to wake up the card, since doing so is impossible. Luckily the
only way the card can get into sleep state is if we had a good enough
tuning to send it the command to put it into sleep, so presumably that
"good enough" tuning is enough to wake us up, at least with a few
retries.

We want SDIO drivers to be able to temporarily stop retuning when the
driver knows that the SDIO card is not in a state where retuning will
work (maybe because the card is asleep). We'll move the relevant
functions to a place where drivers can call them.

There are certain cases, notably when transitioning between sleep and
active state, when Broadcom SDIO WiFi cards will produce errors on the
SDIO bus. This is evident from the source code where you can see that
we try commands in a loop until we either get success or we've tried
too many times. The comment in the code reinforces this by saying
"just one write attempt may fail"
Unfortunately these failures sometimes end up causing an "-EILSEQ"
back to the core which triggers a retuning of the SDIO card and that
blocks all traffic to the card until it's done.
Let's disable retuning around the commands we expect might fail.

Normally when the MMC core sees an "-EILSEQ" error returned by a host
controller then it will trigger a retuning of the card. This is
generally a good idea.
However, if a command is expected to sometimes cause transfer errors
then these transfer errors shouldn't cause a re-tuning. This
re-tuning will be a needless waste of time. One example case where a
transfer is expected to cause errors is when transitioning between
idle (sometimes referred to as "sleep" in Broadcom code) and active
state on certain Broadcom WiFi SDIO cards. Specifically if the card
was already transitioning between states when the command was sent it
could cause an error on the SDIO bus.
Let's add an API that the SDIO function drivers can call that will
temporarily disable the auto-tuning functionality. Then we can add a
call to this in the Broadcom WiFi driver and any other driver that
might have similar needs.
NOTE: this makes the assumption that the card is already tuned well
enough that it's OK to disable the auto-retuning during one of these
error-prone situations. Presumably the driver code performing the
error-prone transfer knows how to recover / retry from errors. ...and
after we can get back to a state where transfers are no longer
error-prone then we can enable the auto-retuning again. If we truly
find ourselves in a case where the card needs to be retuned sometimes
to handle one of these error-prone transfers then we can always try a
few transfers first without auto-retuning and then re-try with
auto-retuning if the first few fail.
Without this change on rk3288-veyron-minnie I periodically see this in
the logs of a machine just sitting there idle:

This reverts commit 29f6589140a10ece8c1d73f58043ea5b3473ab3e.
After that patch landed I find that my kernel log on
rk3288-veyron-minnie and rk3288-veyron-speedy is filled with:
brcmfmac: brcmf_sdio_bus_sleep: error while changing bus sleep state -110
This seems to happen every time the Broadcom WiFi transitions out of
sleep mode. Reverting the commit fixes the problem for me, so that's
what this patch does.
Note that, in general, the justification in the original commit seemed
a little weak. It looked like someone was testing on a SD card
controller that would sometimes die if there were CRC errors on the
bus. This used to happen back in early days of dw_mmc (the controller
on my boards), but we fixed it. Disabling a feature on all boards
just because one SD card controller is broken seems bad.

This is often because ixp4xx_irq_setup lacks a __init

The call to sc_buffer_alloc currently returns NULL (no buffer) or
a buffer descriptor.
There is a third case when the port is down. Currently that
returns NULL and this prevents the caller from properly handling the
sc_buffer_alloc() failure. A verbs code link test after the call is
racy so the indication needs to come from the state check inside the allocation
routine to be valid.
Fix by encoding the ECOMM failure like SDMA. IS_ERR_OR_NULL() tests
are added at all call sites. For verbs send, this needs to treat any
error by returning a completion without any MMIO copy.
