board: rockchip: add Anbernic RGXX3 Series Devices
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).
