[ Upstream commit a9f5f287fa1d47d61dfa8b60f94831174b2ea4d0 ]
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.
