51217cee3a Merge remote-tracking branch 'wireless-next/master' into HEAD
Merge to get the wil6210 changes that a cfg80211 change needs.
A conflict in drivers/net/wireless/ath/ath9k/init.c was just
whitespace changes.

Also fix a semantic conflict due to cw1200 using WoWLAN which
I had modified in my tree.

7c0b6f49db cw1200: Rework SDIO platform support to prevent build problems.
Based on discussions with And Bergmann, this patch changes the SDIO
platform code to default to supporting the Sagrad devices, allowing for
it to be overridden in board setup code.  This renders the cw1200_sagrad
module suplerflous, so it is now removed.

It also moves the documentation that was in the cw1200_sagrad source to
the platform header.

6dd64a304e cw1200: Replace use of 'struct resource' with 'int' for GPIO fields.
The only advantage of 'struct resource' is that it lets us assign names
as part of the platform data.  Unfortunately since we are using platform
data, we are already limited to a single instance of each driver,
rendering this moot.

So, replace the struct resources with ints, resulting in cleaner code.

This was based on a suggestion from Arnd Bergmann.

debff6184c iwlwifi: mvm: implement D3 testing
For testing the D3 (WoWLAN) firmware, it is useful to be able
to run the firmware with instrumentation while the host isn't
sleeping and can poke at the firmware debug logging etc.

Implement this by a debugfs file. When the file is opened the
D3 firmware is loaded and all regular commands are blocked.
While the file is being read, poll the firmware's PME status
flag and report EOF once it changes to non-zero. When it is
closed, do (most of) the resume processing. This lets a user
just "cat" the file. Pressing Ctrl-C to kill the cat process
will resume the firwmare as though the platform resumed for
non-wireless reason and when the firmware wants to wake up
reading from the file automatically completes.

Unlike in real suspend, only disable interrupts and don't
reset the TX/RX hardware while in the test mode. This is a
workaround for some interrupt problems that happen only when
the PCIe link isn't fully reset (presumably by changing the
PCI config space registers which the core PCI code does.)

Note that while regular operations are blocked from sending
commands to the firmware, they could still be made and cause
strange mac80211 issues. Therefore, while using this testing
feature you need to be careful to not try to disconnect, roam
or similar, and will see warnings for such attempts.

Als note that this requires an upcoming firmware change to
tell the driver the location of the PME status flag in SRAM.
D3 test will fail if the firmware doesn't report the pointer.

9c8426fc79 ath9k_hw: fix PA predistortion miscalibration
If any bins from the training data are skipped (i != max_index), the
calculated compensation curve gets distorted, and the signal will be
wildly overamplified. This may be the cause of the reported hardware
damage that was caused by PA predistortion (because of which PAPRD was
disabled by default).

When calculating the x_est, Y, theta values, the use of max_index and i
was reversed. i points to the bin index whereas max_index refers to the
index of the calculated arrays.

Note that PA predistortion is still disabled, it will be re-enabled
after it has been properly validated.
