Subject: [PATCH 0/4] ath11k: Add caldata download support from file/EEPROM

From: Anilkumar Kolli <[email protected]>

Clean up BDF download functions to add caldata load support from EEPROM.
Remove unnecessary macros.
Write common function to send QMI BDF download request.
Allow caldata file load support for multiple PCI devices.

Anilkumar Kolli (4):
ath11k: use hw_params to access board_size and cal_offset
ath11k: clean up BDF download functions
ath11k: add caldata file for multiple radios
ath11k: add caldata download support from EEPROM

Subject: [PATCH 2/4] ath11k: clean up BDF download functions

From: Anilkumar Kolli <[email protected]>

In current code, AHB/PCI uses two separate functions to download
BDF file. Refactor code and make a common function to send QMI BDF
download request for both AHB and PCI devices. This patch has no
functional change.

Tested-on: IPQ8074 hw2.0 AHB WLAN.HK.2.4.0.1-00009-QCAHKSWPL_SILICONZ-1
Tested-on: QCN9074 hw1.0 PCI WLAN.HK.2.4.0.1-01838-QCAHKSWPL_SILICONZ-1

Subject: [PATCH 4/4] ath11k: add caldata download support from EEPROM

From: Anilkumar Kolli <[email protected]>

Firmware updates EEPROM support capability in QMI FW caps, send QMI BDF
download request message with file type EEPROM, to get caldata download
from EEPROM. Firmware takes more time to update cal data from EEPROM, so
increase QMI timeout.

You don't mention anything about cal_size. I'll add this to the commit
log:

cal_size was unused, so remove that.

FW advertizes calibration data support from EEPROM through
'eeprom_read_timeout' in
QMI FW Capability message. Ath11k sends BDF download request with file
type
'ATH11K_QMI_FILE_TYPE_EEPROM'. FW has logic to read calibration data
from EEPROM and
process the calibration data. FW takes more time to process the
calibration data from
EEPROM so increase QMI timeout to 10msec.

Thanks, I now copied the updated commit log below. And do note that the
timeout is 10 s, not 10 ms.

ath11k: add caldata download support from EEPROM

In some devices the calibration data is stored to EEPROM within the device so add
support for that.

The firmware advertises the calibration data support from EEPROM through
'eeprom_read_timeout' in the QMI firmware capability message. ath11k sends
boardfile download request with file type 'ATH11K_QMI_FILE_TYPE_EEPROM'. The
firmware has logic to read calibration data from EEPROM and process the
calibration data.

As now the firmware takes more time to process the calibration data from EEPROM
so increase QMI timeout to 10 seconds.
