Commit Message

i.MX8MP uses 3 clocks, so soften the restrictions for clocks & clock-names.
This SoC requires a power-domain for this peripheral to use. Add it as
a required property.

Fixes: f5419cb0743f ("dt-bindings: lcdif: Add compatible for i.MX8MP")

Changes in v3:
* Removed power-domains minItems: 1 constraint

Changes in v2:
* Squash both patches into one
* Split the conditionals from fsl,imx6sx-lcdif
* Mark power-domains as required for fsl,imx8mp-lcdif
* Ignored the A-b & R-b due to reorganization
