reg is not optional.
+- qca,clk-25mhz: Defines that a 25MHz clock is used
+- qca,no-eeprom: Indicates that there is no physical EEPROM connected to the
+ ath9k wireless chip (in this case the calibration /
+ EEPROM data will be loaded from userspace using the
+ kernel firmware loader).
+- qca,disable-2ghz: Overrides the settings from the EEPROM and disables the

+- qca,disable-5ghz: Overrides the settings from the EEPROM and disables the

+- mac-address: See ethernet.txt in the parent directory
