The calibration data for devices w/o a separate EEPROM chip can be specified via the 'eeprom_data' field of 'ath9k_platform_data'. The 'eeprom_data' is usually filled from board specific setup functions. It is easy if the EEPROM data is mapped to the memory, but it can be complicated if it is stored elsewhere. The patch adds support for loading of the EEPROM data via the firmware API to avoid this limitation. Signed-off-by: Gabor Juhos <juhosg@openwrt.org> Signed-off-by: John W.
