From: Chris Morgan <macromorgan@xxxxxxxxxxx> Add support for the Anbernic RG-Nano handheld gaming device Changes since V3: - Added PHY to the OHCI and EHCI nodes. Note that the PHY driver currently forces the PHY to host mode always; a correction to the PHY driver or removal of the phy values from the OHCI and EHCI nodes are necessary to get otg mode working properly. - Disabled SoC RTC in favor of external clock. The SoC RTC is not set up correctly in hardware and runs fast, whereas the external RTC keeps accurate time. This matches the BSP. - Added labels to GPIO pins to aid in readability. 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.
