X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=638b8eb43b2a143f151045e66e695ba91b4a1a7c;p=linux.git

dt-bindings: arm: rockchip: Document Radxa ROCK 4C+

Document the dt-bindings 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@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+.
