[PATCH v2 4/6] arm64: dts: rockchip: Add ArmSoM Sige1

Jonas Karlman
2025-07-10T20:30:28Z

The Sige1 is a single board computer developed by ArmSoM, based on the
Rockchip RK3528A SoC.

Add initial device tree for the ArmSoM Sige1 board.

Signed-off-by: Jonas Karlman <jonas@kwiboo.se>
---
Changes in v2:
- Drop regulator-boot-on from usb 2.0 host regulators (Chukun Pan)
- Change rfkill to sdio-pwrseq (Chukun Pan)
- Drop clock-output-names prop from rtc node (Chukun Pan)
- Add bluetooth and wifi nodes (Chukun Pan)
- Enable use of DMA for bluetooth on uart2

Schematics: https://drive.google.com/drive/folders/15uvc2lcOAKP0enXezASUhVFLuzkq3IEX
