Hi Alan,

first I'd like to say thank you for your work on upstream ath79 support!

I've also seen your RFC patch on the linux-wireless list. you may want
to split things to make it easier to review though (that's my personal
opinion):
1. add the 25MHz clock handling to the existing ath9k_of_init function
2. add OF support to ath9k/ahb.c
3. add devdata support (maybe to eeprom.c instead of ahb.c since there
are many boards with ath9k PCI without EEPROM - there devdata support
could be interesting as well)

with just 1. and 2. you should be able to get the ath9k AHB devices
running if you add the "qca,no-eeprom" property and then provide the
EEPROM data using a firmware hotplug script (see [0] and [1])


Regards,
Martin
