Carrier board often referred as baseboard. For making complete SBC or any other industrial boards, these carrier boards will be used with associated SOMs.
Radxa has Dalang carrier board which supports on-board peripherals, ports like USB-2.0, USB-3.0, HDMI, MIPI DSI/CSI, eDP, Ethernet, WiFi, PCIe, USB-C, 40-Pin GPIO header and etc.
Right now Dalang carrier board is used with two SBC-variants: Rock Pi N10 => VMARC RK3399Por SOM + Dalang carrier board Rock Pi N8 => VMARC RK3288 SOM + Dalang carrier board(+codec)
So add this carrier board dtsi as a separate file in ARM directory, so-that the same can reuse it in both rk3288, rk3399pro variants of Rockchip SOMs.
Sync this dtsi from linux-next v5.7-rc1.
