arm64: dts: rockchip: add support for Powkiddy RGB30
The Powkiddy RGB30 is a portable game device based on the Rockchip RK3566 SoC. It has GPIO buttons on the face and sides for input, stereo speakers, a 720x720 4 inch DSI display, a USB-C host port and a USB-C peripheral port, dual SD card slots, WiFi, Bluetooth, and 1GB of RAM. Working/Tested: - SDMMC - UART (for debugging) - Buttons - Charging/battery/PMIC - Speaker/Headphones - USB - WiFi - Bluetooth - Display (at 59.04hz) Signed-off-by: Chris Morgan <macromorgan@hotmail.com> Link: https://lore.kernel.org/r/20231013183918.225666-6-macroalpha82@gmail.com Signed-off-by: Heiko Stuebner <heiko@sntech.de>
