Sure, but I do not have any board to test this.

Put whoever the original author of the binding was here, failing that
probably the platform maintainers for omap.

Pretty sure you need a type here:
    $ref: /schemas/types.yaml#/definitions/string

Please add an items list here for each clock with a description.

Where did the minItems: 2 come from? The text binding suggests that 1
would be valid.
