From: Shawn Guo <shawn.guo@xxxxxxxxxx> This is basically a rewrite of Jun's ZTE ZX pinctrl driver. It has quite a few significant changes from Jun's version. - It handles the relation between main and auxiliary controllers internally, and then we do not need to export core function pin_request(). - Update bindings document with a ASCII figure to illustrate how this 'hybrid' pin controller hardware works. - Rather than making up pin name with the fake port name and pin number, name the pins in the exactly same way how hardware manual name them. - Instead of encoding AON register data, calculate the offset and bit position from pin id. - Utilize the generic groups and functions support from core to save quite some code in our driver. - Simplify the data structures and add documents for important ones. - Clean up some unnecessary function calls.
