I have this patch queued up but I notice that it seems to introduce
the following warnings. Can this be addressed somehow?

Warning (reg_format): "reg" property in /lvds-encoder/ports/port@0 has invalid length (4 bytes) (#address-cells = 2, #size-cells = 1)
Warning (reg_format): "reg" property in /lvds-encoder/ports/port@1 has invalid length (4 bytes) (#address-cells = 2, #size-cells = 1)
Warning (avoid_default_addr_size): Relying on default #address-cells value for /lvds-encoder/ports/port@0
Warning (avoid_default_addr_size): Relying on default #size-cells value for /lvds-encoder/ports/port@0
Warning (avoid_default_addr_size): Relying on default #address-cells value for /lvds-encoder/ports/port@1
Warning (avoid_default_addr_size): Relying on default #size-cells value for /lvds-encoder/ports/port@1
