I see that you applied my previous patch "gpio: ath79: Convert to the
state container design pattern", this series was supposed to replace
this patch. I'm sorry I forgot to mention this. That old patch doesn't
make much sense any more as most of the code it changed just get
dropped in the move to GPIO_GENERIC.

I'm going to split the compile test support to a separate patch.

Hm you can tell me exactly which commits I need to revert
or something ... I cannot rebase the tree now.

It would be best if you cook a GPIO_GENERIC patch based on
devel.
