Anbernic RG353P and RG503 are both RK3566 based handheld gaming devices from Anbernic. Both devices have: - 2 SDMMC slots. - A Realtek rtl8821cs WiFi/Bluetooth adapter. - A mini HDMI port. - A USB C host port and a USB C otg port (currently only working as device). - Multiple GPIO buttons and a single ADC button. - Dual analog joysticks controlled via a GPIO mux. - A headphone jack with amplified stereo speakers via a SGM4865 amp. - A PWM based vibrator for force feedback. The RG353P has: - 2GB LPDDR4 RAM. - A 32GB eMMC. - A 3.5 inch 640x480 4-lane DSI panel of unknown origin with an i2c controlled touchscreen (touchscreen is a Hynitron CST340). The RG503 has: - 1GB LPDDR4 RAM. - A 5 inch 960x544 AMOLED 2-lane DSI/DBI panel manufactured by Samsung with part number ams495qa04. Data for this panel is provided via the DSI interface, however commands are sent via a 9-bit 3-wire SPI interface. The MISO pin of SPI3 of the SOC is wired to the input of the panel, so it must be bitbanged. This devicetree enables the following hardware: - HDMI (plus audio). - Analog audio, including speakers. - All buttons. - All SDMMC/eMMC/SDIO controllers. - The ADC joysticks (note a pending patch is required to use them). - WiFi/Bluetooth (note out of tree drivers are required). - The PWM based vibrator motor. The following hardware is not enabled: - The display panels (drivers are being written and there are issues with the upstream DSI and VOP2 subsystems). - Battery (driver pending). - Touchscreen on the RG353P (note the i2c2 bus is enabled for it).
