+Subject: [PATCH 1/4] ath9k: move duplicated debug message to
+ 'ath9k_hw_nvram_read'
+
+The fill_eeprom functions are printing the same
+debug message in case the 'ath9k_hw_nvram_read'
+function fails. Remove the duplicated code from
+fill_eeprom functions and add the ath_dbg call
+directly into 'ath9k_hw_nvram_read'.

+Subject: [PATCH 3/4] ath9k: use 'struct ath_hw *' as the first argument for
+ 'ath9k_hw_nvram_read'
+
+The 'ath9k_hw_nvram_read' function takes a
+'struct ath_common *' as its first argument.
+Almost each of its caller has a 'struct ath_hw *'
+parameter in their argument list, and that is
+dereferenced in order to get the 'struct ath_common'
+pointer.
+
+Change the first argument of 'ath9k_hw_nvram_read'
+to be a 'struct ath_hw *', and remove the dereference
+calls from the callers.
+
+Also change the type of the first argument of the
+ar9300_eeprom_read_{byte,word} functions.

+Subject: [PATCH 4/4] ath9k: allow to load EEPROM content via firmware API
+
+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.
