VMARC RK3399Pro SOM is a standard SMARC SOM design with Rockchip RK3399Pro SoC, which is designed by Vamrs.
Specification:
- Rockchip RK3399Pro
- PMIC: RK809-3
- SD slot, 16GiB eMMC
- 2xUSB-2.0, 1xUSB3.0
- USB-C for power supply
- Ethernet, PCIe
- HDMI, MIPI-DSI/CSI, eDP
Add initial support for VMARC RK3399Pro SOM, this would use with associated carrier board.
Sync this dtsi from linux-next v5.7-rc1.
