Subject: [PATCH] ath10k: add BMI parameters to fix calibration from
|
||
|
|
DT/pre-cal
|
||
|
|
|
||
|
|
QCA99X0, QCA9888, QCA9984 supports calibration data in
|
||
|
|
either OTP or DT/pre-cal file. Current ath10k supports
|
||
|
|
Calibration data from OTP only.
|
||
|
|
|
||
|
|
If caldata is loaded from DT/pre-cal file, fetching board id
|
||
|
|
and applying calibration parameters like tx power gets failed.
|
||
|
|
|
||
|
|
error log:
|
||
|
|
[ 15.733663] ath10k_pci 0000:01:00.0: failed to fetch board file: -2
|
||
|
|
[ 15.741474] ath10k_pci 0000:01:00.0: could not probe fw (-2)
|
||
|
|
|
||
|
|
This patch adds calibration data support from DT/pre-cal
|
||
|
|
file. Below parameters are used to get board id and
|
||
|
|
applying calibration parameters from cal data.
|
||
|
|
|
||
|
|
EEPROM[OTP] FLASH[DT/pre-cal file]
|
||
|
|
Cal param 0x700 0x10000
|
||
|
|
Board id 0x10 0x8000
|
||
|
|
|
||
|
|
Tested on QCA9888 with pre-cal file.
