From: Denis Kalashnikov <denis281...@gmail.com> RB912 needs two ad hoc drivers: gpio-latch and rb91x_nand. So I've ported them from ar71xx and added DTS.
In RFC v1 I added a MFD driver that provided API for manipulating shared gpio lines to gpio-latch and nand drivers. In RFC v2 I just ported gpio-latch and rb91x_nand drivers from ar71xx to ath79 by adding DTS support and usage of a new gpio API (gpiod_*). This way is turned to be more clear and compact. So, I've tried to fix what you guys advised me and here is my patches v1. All seems to be working on my RB912UAG-2HPnD. Except a button and a beeper. The beeper seems is not important thing, but the button is. The button shares gpio 15 with NAND ALE and NAND IO7, but this is not easily supported by the current drivers. May be we need ad hoc driver for button. Or may be there is a more general solution for this problem (like rb91x-gpio driver that arbitrates all gpio lines instead of gpio-latch). This can be fixed in the next patches.
