[PATCH v1] dt-bindings: display: rockchip: convert rockchip vop bindings to yaml

[Johan Jonker]

Hi,

Question for robh:

In the old txt situation we add/describe only properties that are used
by the driver/hardware itself. With yaml it also filters things in a
node that are used by other drivers like:

assigned-clocks:
assigned-clock-rates:
power-domains:

Should we add or not?

Kind regards,

Johan

PS: Will drop 'rockchip,grf' in v2 for px30, not used in vop driver?
