      ath11k: fix wmi init configuration · 36c7c640
      Karthikeyan Periyasamy authored 
      Assign the correct hw_op ath11k_init_wmi_config_ipq8074 to
the hw IPQ8074. Also update the correct TWT radio count.
Incorrect TWT radio count cause TWT feature fails on radio2
because physical device count is hardcoded to 2. so set
the value dynamically.

Found this during code review.

      ath11k: Fix the hal descriptor mask · ab041d06
      Karthikeyan Periyasamy authored 
      Below listed hal descriptor mask are incorrect, so modify it to correct one
 - CE destination status description meta info mask is increased from
   8 bits to 16 bits from the 0th bit position
 - Rx Reo queue duplicate count mask is decreased from 22 bits to 16 bits
 - Reo threshold status counter sum mask is increased from 24 bits to 26 bits

No functionality impact, these descriptors are currently not used in any
supported platform. But in future if someone referred these descriptor then
ended with wrong values.

Found this during code review.

      ath11k: Fix single phy hw mode · 9fb13b81
      Karthikeyan Periyasamy authored 
      driver not able to bootup in the single radio configured board.
single phy hw mode is converted to invalid hw mode and sent to FW
through wmi init cmd. In that case driver is not receiving wmi
ready event which leads to driver bootup fail. single phy hw mode
is a valid for single radio configured board. so removed the
conversion logic.

      ath11k: Fix number of rules in filtered ETSI regdomain · 6189be7d
      Sven Eckelmann authored 
      The ath11k code will try to insert wheather rader related limits when the
DFS region is set to ETSI. For this reason, it will add two more entries in
the array of reg_rules. But the 2.4.0.1 firmware is prefiltering the list
of reg rules it returns for 2.4GHz PHYs. They will then not contain the
list of 5GHz rules and thus no wheather radar band rules were inserted by
this code.

But the code didn't fix the n_reg_rules for this regulatory domain and PHY
when this happened. This resulted in a rejection by is_valid_rd because it
found rules which start and end at 0khz. This resulted in a splat like:

  Invalid regulatory domain detected
  ------------[ cut here ]------------
  WARNING: at backports-20200628-4.4.60-9a94b73e75/net/wireless/reg.c:3721
  [...]
  ath11k c000000.wifi1: failed to perform regd update : -22

The number of rules must therefore be saved after they were converted from
the ath11k format to the ieee80211_regdomain format and not before.

Tested with IPQ8074 WLAN.HK.2.4.0.1.r1-00019-QCAHKSWPL_SILICONZ-1

      ath11k: Initialize complete alpha2 for regulatory change · 383a32cd
      Sven Eckelmann authored 
      The function ath11k_wmi_send_init_country_cmd is taking 3 byte from alpha2
of the structure wmi_init_country_params. But the function
ath11k_reg_notifier is only initializing 2 bytes. The third byte is
therefore always an uninitialized value.

The command can happen to look like

  0c 00 87 02 01 00 00 00 00 00 00 00 43 41 f8 00

instead of

      ath11k: cold boot calibration support · 02f9d3c1
      Govindaraj Saminathan authored 
      cold boot calibration is the process to calibrate all the channels
during the boot-up to avoid the calibration delay during the
channel change.
During the boot-up, firmware started in cold boot calibration mode
Firmware calibrate all channels and generate CalDb(DDR).
Subsequent wifi bringup will reuse the same CalDb.
Firmware is restarted in normal mode to continue the normal operation.

caldb memory address send to firmware through the QMI message.Firmware
use this address to store the caldb data and use it until next reboot.

This will give the improvement during the channel change. But it is
increasing the boot-up time(up to 15sec depend on number of radios).
So if the user want to reduce the boot-up time and accepting for channel
change delay, user can disable this feature using the module param
cold_boot_cal=0.

      ath11k: search DT for qcom,ath11k-calibration-variant · 14f43c5f
      Sven Eckelmann authored 
      Board Data File (BDF) is loaded upon driver boot-up procedure. The right
board data file is identified on IPQ6018 using bus, qmi-chip-id and
qmi-board-id.

The problem, however, can occur when the (default) board data file cannot
fulfill with the vendor requirements and it is necessary to use a different
board data file.

This problem was already solved on ath10k by adding a ",variant=.*" at the
end of the board name. The same functionality must also be provided for
ath11k.

The device tree requires an additional string to define the variant name

    wifi@c000000 {
        status = "okay";
        qcom,ath11k-calibration-variant = "Cigtech-WF-188";
    };

This would create the boarddata identifier for the board-2.bin search

 *  bus=ahb,qmi-chip-id=0,qmi-board-id=18,variant=Cigtech-WF-188

      dt: bindings: add new dt entry for ath11k calibration variant · 77581df8
      Sven Eckelmann authored 
      The bus + qmi-chip-id + qmi-board-id is not enough to identify the correct
board data file on IPQ6018 based devices. Multiple different boards share
the same values. Only the original reference designs can currently be
identified and loaded from the board-2.bin. But these will not result in
the correct calibration data when combined with the pre-calibration data
from the device.

An additional "variant" information has to be provided to select the
correct board data for a design which was modified by an ODM. This follows
the same approach as ath10k.

after hif_stop. And it should be cancelled before napi_synchronize in

should have no napi_schedule before napi_synchronize, otherwise it
lead napi_synchronize wait untill napi_complete.

Also tested with stock kernel plus this patch, with firmware
10.2.4-1.0-00037

This test case was to bring up 5 vap on a radio and fake a firmware
crash.  Make sure ap interfaces continue to function properly.
