In other words, port@0 is defined to be the rgb port. Now, if this is one of several modes for the video port, then that is a different story. > + and may contain the optional property: > + > + - reg: 24 bits value which defines how the video controller > + output is wired to the TDA998x input (video pins) > + When absent, the default value is <0x230145>. This is not really how reg is intended to be used.
