please add an entry to Documentation/devicetree/bindings/arm/rockchip.yaml
for your board and if necessary also a vendor-prefix to
Documentation/devicetree/bindings/vendor-prefixes.(yaml?)
See below.

mode = "Mecer Xtreme Mini S6";
compatible = "mecer,xms6", "rockchip,rk3229";
(and as written above, add a vendor-prefix for mecer)
