This patch series brings complete refactoring to the Ralink pinctrl driver and its subdrivers. The mt7620 pinctrl subdriver supports MT7628 and MT7688 SoCs along with MT7620. These two share the same pin layout. The code used for MT7628 and MT7688 is renamed from MT7628/mt7628an to MT76X8. Ralink pinctrl driver is called rt2880 which is the name of the Ralink RT2880 SoC. A subdriver for the Ralink RT2880 SoC is called rt288x. Rename rt2880 to ralink. Rename code from pinmux to pinctrl for where the operation is not about the muxing of pins. Rename rt288x pinctrl subdriver for the RT2880 SoC to rt2880. Variables for functions include "grp" on the Ralink MT7620 and MT7621 subdrivers. Rename them to "func" instead as they define the functions for the pin groups. This is already the case for the other 3 subdrivers; RT2880, RT305x, RT3883. Fix Kconfig to call the subdrivers, well, subdrivers. Add new compatible strings for each subdriver and update DT binding accordingly. Add Ralink pinctrl driver to MAINTAINERS and add me and Sergio as the maintainers. Finally, fix the current rt2880 documentation and add binding for all of the subdrivers. I have the patches here should anyone prefer to read them there: https://github.com/arinc9/linux/commits/ralink-pinctrl-refactor Ralink pinctrl driver and the subdrivers were compile tested. MT7621 pinctrl subdriver was tested on a private mt7621 board.
