When porting RB91xG ad hoc drivers (gpio-latch and rb91x-nand) from ar71xx to ath79, I made a decision to rework this to more clear design in my opinion: MFD driver that requests and controls the gpio lines, and separate NAND driver and GPIO-latch driver that uses API of the MFD driver (like how in rb4xx-clpd is done). ar71xx gpio-latch is very good, but somewhat hacky, so I don't think that it can be general driver for gpio controller on a latch. I could be wrong. Also it is my first attempt to port OpenWrt to a device, so I need a review from the community. I've tested all these on my RB912UAG-2HPnD. Gigabit Ethernet, 2.4GHz Wi-Fi, sysupgrade and LEDs:) are working for me. Not working: beeper, button and USB port/mPCIe (has not tested yet).
