Subject: [PATCH v6 1/2] dt-bindings: cros-ec: Reorganize property availability
Various properties in the cros-ec binding only apply to different
compatible strings. For example, the interrupts and reg property are
required for all cros-ec devices except for the rpmsg version. Add some
conditions to update the availability of properties so that they can't
be used with compatibles that don't support them.
