[RFC PATCH v1 0/6] add rk3318 A95X Z2 board

[Johan Jonker]

Hi Alex,

Thanks for reporting!
With rockchip,dw-hdmi.yaml all kind notifications rk3328/rk3399 but not
for ddc-i2c-scl-*
Submitted by Laurent, but not reviewed/fixed nodes together with the
Rockchip mail group. Someone has to look at/fix it...

dt-bindings: display: rockchip: dw-hdmi: Convert binding to YAML
https://patchwork.kernel.org/project/linux-renesas-soc/patch/20210114064437.5793-6-laurent.pinchart+renesas@ideasonboard.com/

Will change that for A95X-Z2. Waiting for some more comments... ;)

Johan
