bdfbf06c2c rtw89: support DAV efuse reading operation
DAV is an another efuse region that new chip, like 8852C, has this region.
Extend the code to read it, and convert the physical map to logical map
followed by original logical map.

e8955811c6 rtw89: add chip_info::{h2c,c2h}_reg to support more chips
This is a register-based H2C/C2H interface to exchange data with firmware.
Since the register addresses of 8852A and 8852C are different, add fields
to chip_info to support this.

e4133f269e rtw89: pci: use a struct to describe all registers address related to DMA channel
We have had a struct rtw89_pci_ch_dma_addr to describe register address,
so use it as regular. Since the addresses should be changed dynamically
according to operating mode, I don't change it to be constant.

These changes don't affect the logic, so I put them in this separated

00a883e680 mt76: fix dfs state issue with 160 MHz channels
When operating on a mix of DFS and non-DFS channels, the driver only checks
the CAC status of the control channel. This causes beacons/tx to fail if the
control channel is on a non-DFS channel.
Fix this by calling cfg80211_reg_can_beacon to determine the DFS status of

771cd8d4c3 mt76: mt7915e: Fix degraded performance after temporary overheat
mt7915e registers a cooling_device with wrong semantics:

1. cooling_device expect that higher states values should cool more, but
   mt7915e did the opposite...  with the exception of state == 0, which
   should "disable thermal management", but does not seem to have any
   effect since the previous state is kept.

The result is that when the thermal zone heats up a bit and bumps the
cooling_device state from 0 to 1 to cool a bit, the performance is
destroyed, and when going back from 1 to 0, the performance stays bad.

2. Reading the cooling_device state does not always return the last
   written state, but can return the actual hardware throttle state,
   which is different.

This is a problem because the mt7915 firmware actually implement the
equivalent of a thermal zone with trip points.  Setting the cooling
device state actually changes the throttles at each trip point, so the
following could occur if the first issue is fixed:

- thermal subsystem set state to 100% power (state=0)
- mt7915e driver set trip throttles to [100%, 50%, 25%, 12%]
- hardware heats up and decides to switch to 50% power
- thermal subsystem see that power is 50% (state=50), decide to increase
  it to 60% (state=40) because the rest of the system is cool.
- mt7915e driver set trip throttle to [60%, 30%, 15%, 7%]
- hardware thus switches to 30% power
[race to the bottom continues...]

This patch corrects the semantics of the cooling_device to the one that
the thermal subsystem expect it.

49ffac5907 ath10k: fix pointer arithmetic error in trace call
Reading through the commit history, it looks like
there is no special need why we must skip the first 4 bytes
in this trace call:

trace_ath10k_htt_rx_desc(ar, (void*)rx_desc + sizeof(u32),
			 hw->rx_desc_ops->rx_desc_size - sizeof(u32));

found in the function ath10k_htt_rx_amsdu_pop in the file htt_rx.c

i think the original author
(who is also the one who added rx_desc tracing capabilities
in a0883cf7e7) just wanted to trace the rx_desc contents,
ignoring the fw_rx_desc_base info field
(which is the part being skipped over).
But the trace_ath10k_htt_rx_desc later added
don't care about skipping it, so it may be good
to uniform this call to the others in the file.
But this would change the output of the trace and
thus it may be a problem for tools that rely on it.
Therefore I propose until further discussion
to just keep it as it is and just fix the pointer arithmetic bug.

Add missing void* cast to rx descriptor pointer in order to
properly skip the initial 4 bytes of the rx descriptor
when passing it to trace_ath10k_htt_rx_desc trace function.

This fixes the pointer arithmetic error detected
by Dan Carpenter's static analysis tool.

Fixes: 6bae9de622 ("ath10k: abstract htt_rx_desc structure")

152094dd8c carl9170: Replace zero-length arrays with flexible-array members
There is a regular need in the kernel to provide a way to declare
having a dynamically sized set of trailing elements in a structure.
Kernel code should always use “flexible array members”[1] for these
cases. The older style of one-element or zero-length arrays should
no longer be used[2].

691425b4a4 ath11k: add dbring debug support
Target copies spectral report and CFR report through dbring to
host for further processing. This mechanism involves ring and
buffer management in the Host, FW, and uCode, where improper
tail pointer update issues are seen.

This dbring debug support help to debug such issues by tracking
head and tail pointer movement along with the timestamp at which
each buffer is received and replenished.

Provide a debugfs interface to enalbe/disable dbring debug
support and dump the dbring debug entries.

Also introduced a new hardware param to add dbring debugfs support
for few hardwares which are using dbings.

Usage:

echo <dbr_id> <val> > /sys/kernel/debug/ath11k/ipq8074_2/
mac0/enable_dbr_debug

dbr_id: 0 for spectral and 1 for CFR
val: 0 - disable, 1 - enable.
