[PATCH 6/6] arm64: dts: rockchip: Add Anbernic RG-DS

Tue Jan 13 11:57:21 PST 2026
From: Chris Morgan <macromorgan at hotmail.com>
Add device tree for the Anbernic RG-DS, based on the Rockchip RK3568.
All hardware is currently working except for the accelerometer, the
speaker output, and one of the two battery gauges. A bug in the
Rockchip VOP2 driver is currently causing the device to pause for 30
seconds at boot and is being investigated.
The Anbernic RG-DS includes the following (supported) hardware:
- 2 640x480 DSI display screens with touch.
- 21 buttons.
- 2 Analog joysticks.
- 3 LEDs (red and green LED share the same housing).
- 32GB eMMC, 1 SDMMC slot.
- RTL8821CS WiFi/Bluetooth combo
- 1 USB 2.0 port in host mode, 1 USB 2.0 port in peripheral mode.
- 3.5mm headphone jack with play button support.
- 4000mAH battery
The following hardware has incomplete driver support and is not yet
working:
- An Invensense icm42607p accelerometer.
- Two Awinic aw87391 speaker amplifiers.
- A Cellwise cw2015 battery monitor, which appears to conflict with
the rk817 charger driver at the moment.
