[PATCH v3 3/3] arm64: dts: rockchip: rk3399: Radxa ROCK 4C+

Wed Aug 31 21:18:10 PDT 2022
> Add support for Radxa ROCK 4C+ SBC.
>
> Key differences of 4C+ compared to previous ROCK Pi 4.
> - Rockchip RK3399-T SoC
> - DP from 4C replaced with micro HDMI 2K at 60fps
> - 4-lane MIPI DSI with 1920*1080
> - RK817 Audio codec
>
> Also, an official naming convention from Radxa mention to remove
> Pi from board name, so this 4C+ is named as Radxa ROCK 4C+ not
> Radxa ROCK Pi 4C+.

> Changes for v3:
> - updated commit message
> - include sdhci in aliases
> - add i2s2
> - add sdmmc cd-gpios
> - use rk3399-t-opp.dtsi
> Changes for v2:
> - s/vcc-sys/vcc5v0-sys-regulator
> - used proper node name 'regulator' for syr828 regulator nodes.
> - fix line wrapping.
