Yu Wang 50e79e2525 ath10k: fix kernel panic issue during pci probe
If device gone during chip reset, ar->normal_mode_fw.board is not
initialized, but ath10k_debug_print_hwfw_info() will try to access its
member, which will cause 'kernel NULL pointer' issue. This was found
using a faulty device (pci link went down sometimes) in a random
insmod/rmmod/other-op test.
To fix it, check ar->normal_mode_fw.board before accessing the member.

Wojciech Dubowik 8da58553cc ath9k: Use calibrated noise floor value when available
AR9003 series allows to calibrate noise floor for different frequency
bins. Once it's done it's possible to get more accurate rssi/signal
values over whole frequency band at a given temperature.
The RSSI/signal accuracy reported by calibrated RF cards improves
from 6 to up to 2dB.

This could be interesting for application which require good signal
accuracy like roaming or mesh protocols.

Maya Erez 81b35afa49 wil6210: support parsing brd file address from fw file
In order to allow using the same brd file across different
11ad chips, the address for loading the brd file should be
part of the FW file, instead of the brd file. The brd file is
expected to include only one section.
To allow backward compatibility the driver reads the
address from the brd file in case it is not included in the
FW file.

Lior David 70bcc658c0 wil6210: fix random failure to bring network interface up
Currently when we want to bring the interface up, we first
reset the device which causes the boot loader to run. Then
we halt the device CPU, load FW image and resume the device
CPU.
There are some boot loader versions which perform redundant
memory accesses even when idle. Halting the device CPU
while boot loader access memory can cause the device memory
controller to get stuck, the FW will fail to load and the
network interface will not come up.
For such boot loaders implement a workaround where we freeze
the boot loader before halting the device CPU, so it will not
perform any memory accesses.

 applied back in 2010 in commit 0c8173385e ("rtl8192ce: Add new

 vendor, demanding upstream community and users. So big thank you to

====================
wireless-drivers-next patches for 4.16

Here are patches which have been accumulating over the holidays and
after the New Year. Business as usual and nothing special really
standing out.

But what's noteworthy here is that Larry Finger is stepping down as
the rtlwifi maintainer. He has been maintaining rtlwifi since it was
applied back in 2010 in commit 0c8173385e ("rtl8192ce: Add new
driver") and it has been no easy role trying to juggle between the
vendor, demanding upstream community and users. So big thank you to
Larry for all his efforts!

David S. Miller 19d28fbd30 Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net
BPF alignment tests got a conflict because the registers
are output as Rn_w instead of just Rn in net-next, and
in net a fixup for a testcase prohibits logical operations
on pointers before using them.

Also, we should attempt to patch BPF call args if JIT always on is
enabled.  Instead, if we fail to JIT the subprogs we should pass
an error back up and fail immediately.

Colin Ian King 4c8cf8df2f wcn36xx: fix incorrect assignment to msg_body.min_ch_time
The second assignment to msg_body.min_ch_time is incorrect, it
should actually be to msg_body.max_ch_time.

Thanks to Bjorn Andersson for identifying the correct way to fix
this as my original fix was incorrect.

Maya Erez a8fd16d7a1 wil6210: prevent parallel suspend and dump collection
Suspend and crash dump operations can happen simultaneously
in case there is a FW assert during the suspend procedure
or when SSR calls all the devices crashdump callbacks.

To prevent that, a new flag is added, indicating that the
dumps collection is in progress, in order to allow the
suspend/reset decline if the dumps collection already started.

Loic Poulain 0856655a25 wcn36xx: Fix dynamic power saving
Since driver does not report hardware dynamic power saving cap,
this is up to the mac80211 to manage power saving timeout and
state machine, using the ieee80211 config callback to report
PS changes. This patch enables/disables PS mode according to
the new configuration.

Remove old behaviour enabling PS mode in a static way, this make
the device unusable when power save is enabled since device is
forced to PS regardless RX/TX traffic.

Alan Liu 703f261dd7 ath10k: add memory dump support for QCA6174/QCA9377
Add memory dump to the firmware crash data file which is provided to user space
via devcoredump interface. This makes it easier for firmware engineers to debug
firmware crashes.

Due to increased memory consumption the memory dump is disabled by default. To
enable it make sure that bit 3 is set in coredump_mask module parameter:

modprobe ath10k_core coredump_mask=0xffffffff

When RAMDUMP is enabled a buffer for the dump is allocated with vmalloc during
device probe. The actual memory layout is different in hardware versions and
the layouts are defined in coredump.c. The memory is split to regions and, to
get even finegrained control of what to copy, the region can split to smaller
sections as not all registers are readable (which could cause the whole system
to stall).

Kalle Valo 5c9d0a2020 ath10k: add coredump_mask module parameter
For memory dump support (it consumes quite a lot of memory) we need to control
what is exactly stored to the crash dump. Add a module parameter call
coredump_mask to do that. It's a bit mask of these values:

enum ath10k_fw_crash_dump_type {
	ATH10K_FW_CRASH_DUMP_REGISTERS = 0,
	ATH10K_FW_CRASH_DUMP_CE_DATA = 1,

	ATH10K_FW_CRASH_DUMP_MAX,
};

For example, if we only want to store CE_DATA we would enable bit 2:

modprobe ath10k_core coredump_mask=0x2
