Subject: [PATCH 1/7] wifi: ath11k: Fix register write failure on QCN9074

Commit 56c8ccf331bd ("ath11k: Add register access logic for WCN6750")
regressed QCN9074. With the above mentioned commit, writes are failing
for some registers on QCN9074 although the device seems to work
normally.

ath11k_pci 0000:03:00.0: failed to set pcie link register0x01e0e0a8: 0xffffffff != 0x00000010
ath11k_pci 0000:03:00.0: failed to set sysclk: -110

PCIe devices in ath11k (QCA6390, WCN6855, QCN9074, WCN6750) use window
concept for register accesses. There are two schemes, dynamic & static
window.

In dynamic window scheme, a single window(region in the BAR) is mapped
either to CE or DP register windows at any give time. QCA6390 & WCN6855
follow this scheme for register accesses.

In static window scheme, CE & DP register windows are statically mapped
to separate regions with in the BAR so that there is no switching of
register windows between CE & DP register accesses. QCN9074 & WCN6750
follow this scheme although the window start offsets are different for
QCN9074 & WCN6750.

QCN9074 uses 3rd & 2nd window for DP & CE register accesses respectively
whereas WCN6750 uses 1st & 2nd window for DP & CE. In QCN9074, along with
2nd & 3rd windows, 1st window is also used for certain configurations
which commit 56c8ccf331bd ("ath11k: Add register access logic for WCN6750")
did not account for and hence the regression.

Fix this by going back to the original way of accessing the registers on
QCN9074. Since this diverges from WCN6750 way of accessing registers, it
is required to register window_read32/window_write32() pci_ops for WCN6750.
We can also get rid of dp_window_idx & ce_window_idx members in hw_params,
so remove them.

Also add a new API ath11k_pcic_register_pci_ops() for registering pci_ops
to the ath11k core. This API checks for mandatory pci_ops() and reports
error if those are missing. Also initialize unused pci_ops to NULL.

Tested-on: WCN6750 hw1.0 AHB WLAN.MSL.1.0.1-00887-QCAMSLSWPLZ-1
Tested-on: QCN9074 hw1.0 PCI WLAN.HK.2.6.0.1-00861-QCAHKSWPL_SILICONZ-1

Subject: [PATCH 2/7] Revert "ath11k: add support for hardware rfkill for
 QCA6390"

This reverts commit ec038c6127fa772d2c5604e329f22371830d5fa6. Tyler reported
that on L390 Yoga Thinkpad with QCA6390 the suspend was failing because of this commit.

Tested-on: WCN6855 hw2.0 PCI WLAN.HSP.1.1-03125-QCAHSPSWPL_V1_V2_SILICONZ_LITE-3.6510.9

Subject: [PATCH 3/7] wifi: wil6210: debugfs: fix uninitialized variable use in
 `wil_write_file_wmi()`

Commit 7a4836560a61 changes simple_write_to_buffer() with memdup_user()
but it forgets to change the value to be returned that came from
simple_write_to_buffer() call. It results in the following warning:

  warning: variable 'rc' is uninitialized when used here [-Wuninitialized]
           return rc;
                  ^~

Remove rc variable and just return the passed in length if the
memdup_user() succeeds.

Subject: [PATCH 4/7] wifi: wcn36xx: Rename clunky firmware feature bit enum

The enum name "place_holder_in_cap_bitmap" is self descriptively asking to
be changed to something else.

Rename place_holder_in_cap_bitmap to wcn36xx_firmware_feat_caps so that the
contents and intent of the enum is obvious.

Subject: [PATCH 5/7] wifi: wcn36xx: Move firmware feature bit storage to
 dedicated firmware.c file

The naming of the get/set/clear firmware feature capability bits doesn't
really follow the established namespace pattern of
wcn36xx_logicalblock_do_something();

The feature bits are accessed by smd.c and main.c. It would be nice to
display the found feature bits in debugfs. To do so though we should tidy
up the namespace a bit.

Move the firmware feature exchange API to its own file - firmware.c giving
us the opportunity to functionally decompose other firmware related
accessors as appropriate in future.
