It's useful to permit the customization of the debug uart baud rate. Enable
this and send down the value to the chip if we're enabling debug.

For some reason, the 6004 HW 3.0 definition was missing the value for the
uarttx_pin (used for firmware debug). This corrects this situation.

for_each_compatible_node performs an of_node_get on each iteration, so
a break out of the loop requires an of_node_put.
A simplified version of the semantic patch that fixes this problem is as
follows (http://coccinelle.lip6.fr):
// <smpl>
@@
expression e;
local idexpression n;
@@
for_each_compatible_node(n,...) {
... when != of_node_put(n)
when != e = n
(
return n;

+ of_node_put(n);
? return ...;
)
...
}

John W. Linville says:
====================
pull request: wireless-next 2014-07-25
Please pull this batch of updates intended for the 3.17 stream!
For the mac80211 bits, Johannes says:
"We have a lot of TDLS patches, among them a fix that should make hwsim
tests happy again. The rest, this time, is mostly small fixes."
For the Bluetooth bits, Gustavo says:
"Some more patches for 3.17. The most important change here is the move of
the 6lowpan code to net/6lowpan. It has been agreed with Davem that this
change will go through the bluetooth tree. The rest are mostly clean up and
fixes."
and,
"Here follows some more patches for 3.17. These are mostly fixes to what
we've sent to you before for next merge window."
For the iwlwifi bits, Emmanuel says:
"I have the usual amount of BT Coex stuff. Arik continues to work
on TDLS and Ariej contributes a few things for HS2.0. I added a few
more things to the firmware debugging infrastructure. Eran fixes a
small bug - pretty normal content."
And for the Atheros bits, Kalle says:
"For ath6kl me and Jessica added support for ar6004 hw3.0, our latest
version of ar6004.
For ath10k Janusz added a printout so that it's easier to check what
ath10k kconfig options are enabled. He also added a debugfs file to
configure maximum amsdu and ampdu values. Also we had few fixes as
usual."
On top of that is the usual large batch of various driver updates --
brcmfmac, mwifiex, the TI drivers, and wil6210 all get some action.
Rafał has also been very busy with b43 and related updates.
Also, I pulled the wireless tree into this in order to resolve a
merge conflict...
P.S. The change to fs/compat_ioctl.c reflects a name change in a
Bluetooth header file...

The functionality defined through these flags were actually firmware features
which can change between firmware versions. To make it possible to support
different firmware versions with the same driver, convert the flags to firmware
feature flags.
For backwards compatibility support for old ar6004 firmware FW
API 3 or smaller images we forcefully set the feature bits in the driver.
Starting from FW API 5 the firmware image needs to set them.

Either first 3 bytes of the first received tcp segment or last one
over MTU size file can be loss due to the byte alignment problem.
Although ATH6KL_HTC_ALIGN_BYTES was defined for 'extra bytes for htc header
alignment' in the patch "Fix buffer alignment for scatter-gather
I/O"(1df94a857), there exists the bytes loss issue which means that it will be
truncated 3 bytes in the transmitted file contents if a file which has over MTU
size is transferred through TCP/IP stack. It doesn't look like TCP/IP stack
bug of 3.5 or the latest version of kernel but the byte alignment issue. This
patch is to use the roundup() function for the byte alignment rather than the
predefined ATH6KL_HTC_ALIGN_BYTES.

Julien reported that ar6004 usb device fails to initialise
after host has been rebooted and power is still on for the ar6004 device. He
found out that doing a cold reset fixes the issue.
I wasn't sure what would be the best way to detect if target needs a reset so I
settled on checking a timeout from htc_wait_recv_ctrl_message().

Rename ath6kl_cleanup_vif function as 'ath6kl_cfg80211_vif_stop'
which is the more appropriate name considering the functionality
of the module and vif specific cleanup is actually done by
ath6kl_cfg80211_vif_cleanup. Also move it to cfg80211.c.

Currently AR6004 handles the inactivity timeout resolution
in minutes rather than seconds. So parse the inactivity timeout
to the firmware in minutes. For now we will cleanup the
inactive station entries to the nearest converted minutes
(ex: an inactive time of 70 seconds would take atleast 2 - 3 minutes)
Tested with surprise removal of client cards/host shutdown.

Disallowing any wmi commands while re-initializing the

is done in open/WEP mode. To fix this, clear WMI_READY,
to make sure no wmi command is tried while fw is down.

so that any configuration during fw init time will go through
using wmi commands.

This patch adds support to detect fw error condition by sending
periodic message (heart beat challenge) to firmware. Upon reception
of the message, fw would send a response event to driver. When
there are no reponses from fw for about 5 cmd driver would
trigger the recovery logic assuming that fw has gone into an
error state.
Capable fw will advertise this capability through
ATH6KL_FW_CAPABILITY_HEART_BEAT_POLL bit. This feature
is disabled by default, can be enabled through a modparam
(heart_beat_poll). This modparam also confiures the polling
interval in msecs.

This patch reflects changes in the firmware scheduled scan
implementation to behave better in cases with multiple concurrent vifs.
Major changes:
- scheduled scan filters and state are now programmed per-vif.
- decouple scheduled scan from host sleep.
To maintain graceful failure with old firmwares, a new firmware
capability bit is introduced: ATH6KL_FW_CAPABILITY_SCHED_SCAN_V2.
ath6kl simply won't advertise scheduled scan to cfg80211 if the
SCHED_SCAN_V2 is not supported.
Since firmwares from here on out won't support the previous implicit API
for scheduled scan (set WoW filters and host sleep), bump the firmware
API to protect old drivers.
Unfortunately, due to firmware RAM constraints ath6kl still cannot
expect a scan complete event at the end of a scheduled scan results
cycle, so the sched_scan_timer is retained.
