   3 Subject: ath9k: use correct OTP register offsets for the AR9340 and AR9550
   4
   5 This patch fixes the OTP register definitions for the AR934x and AR9550
   6 WMAC SoC.
   7
   8 Previously, the ath9k driver was unable to initialize the integrated
   9 WMAC on an Aerohive AP121:
  10
  11 | ath: phy0: timeout (1000 us) on reg 0x30018: 0xbadc0ffe & 0x00000007 != 0x00000004
  12 | ath: phy0: timeout (1000 us) on reg 0x30018: 0xbadc0ffe & 0x00000007 != 0x00000004
  13 | ath: phy0: Unable to initialize hardware; initialization status: -5
  14 | ath9k ar934x_wmac: failed to initialize device
  15 | ath9k: probe of ar934x_wmac failed with error -5
  16
  17 It turns out that the AR9300_OTP_STATUS and AR9300_OTP_DATA
  18 definitions contain a typo.
