AFAIK an unwritten rule (at least for the iMX mach) is to specify the
SoC specific compatible and the compatible which is supported by the
driver already, so this should be:

compatible = "fsl,imx8mq-csi", "fsl,imx7-csi";

This is very helpful if we need to handle some quirk for the imx8mq
later on.

Regards,
  Marco
