From: Fabio Estevam <[email protected]>
On i.MX6SX, the LCDIF has an associated power domain.
However, i.MX8MQ does not have an LCDIF power domain.
imx8mq.dtsi has the following compatible string:
compatible = "fsl,imx8mq-lcdif", "fsl,imx6sx-lcdif";
which causes the following dt-schema warning:
imx8mq-evk.dtb: lcd-controller@30320000: 'power-domains' is a required property
from schema $id: http://devicetree.org/schemas/display/fsl,lcdif.yaml#
To prevent this problem, add a specific fsl,imx8mq-lcdif entry in
the driver to properly handle such a power-domain requirement difference.
