Subject: [PATCH] ath9k: fix calibration data endianness
Date: Sat, 15 Apr 2023 17:05:42 +0200	[thread overview]
Message-ID: <20230415150542.2368179-1-noltari@gmail.com> (raw)

BCM63xx (Big Endian MIPS) devices store the calibration data in MTD
partitions but it needs to be swapped in order to work, otherwise it fails:
ath9k 0000:00:01.0: enabling device (0000 -> 0002)
ath: phy0: Ignoring endianness difference in EEPROM magic bytes.
ath: phy0: Bad EEPROM VER 0x0001 or REV 0x00e0
ath: phy0: Unable to initialize hardware; initialization status: -22
ath9k 0000:00:01.0: Failed to initialize device
ath9k: probe of 0000:00:01.0 failed with error -22

Fixes: eb3a97a69be8 ("ath9k: fetch calibration data via nvmem subsystem")
