From: Chris Morgan <macromorgan@xxxxxxxxxxx> Add support for the Anbernic RG-Nano handheld gaming device Changes since V2: - Add display support. - Add USB host support. - Removed CPU frequency and voltage parameters, as CPU regulator may be tied into additional areas that need further testing. - Added regulator names back, as they appear to have been accidentally dropped in v2. - Updated notes to denote all hardware tested and working. Changes since V1: - Added additional pwm pin configs to sun8i-v3s.dtsi and removed default config for pwm0 in lieu of defining it for each board. - Noted in patch notes that additional hardware of UART debug port, USB port (in gadget mode) also work, and that USB host mode does not work. - Identified GPIO responsible for enabling external speaker amplifier and defined it, allowing onboard audio to work. - Removed ac_power_supply node. - Set regulator min and max values to the same value as defined in the schematics. - Removed definition for reg_ldo1. This regulator is hardware configured so the value did not affect anything, however the driver must be updated to support the correct value of 3.3v in this case. - Removed usb0_id_det-gpios as I cannot confirm these are correct.
