The Anbernic RGxx3 is a "pseudo-device" that encompasses the following devices: - Anbernic RG353M - Anbernic RG353P - Anbernic RG353V - Anbernic RG353VS - Anbernic RG503 The rk3566-anbernic-rgxx3.dtsi is synced with upstream Linux, but rk3566-anbernic-rgxx3.dts is a U-Boot specific devicetree that is used for all RGxx3 devices. Via the board.c file, the bootloader automatically sets the correct fdtfile, board, and board_name environment variables so that the correct devicetree can be passed to Linux. It is also possible to simply hard-code a single devicetree in the boot.scr file and use that to load Linux as well. The common specifications for each device are: - Rockchip RK3566 SoC - 2 external SDMMC slots - 1 USB-C host port, 1 USB-C peripheral port - 1 mini-HDMI output - MIPI-DSI based display panel - ADC controlled joysticks with a GPIO mux - GPIO buttons - A PWM controlled vibrator - An ADC controlled button All of the common features are defined in the devicetree synced from upstream Linux. TODO: DSI panel auto-detection for the RG353 devices (requires porting of DSI controller driver and DSI-DPHY driver to send DSI commands to the panel).
