                  TCON can have 1 or 2 channels, usually with the
                  first channel being used for the panels interfaces
                  (RGB, LVDS, etc.), and the second being used for the
                  outputs that require another controller (TV Encoder,
                  HDMI, etc.).

                  If that property is present, specifies the TCON
                  channel the endpoint is associated to. If that
                  property is not present, the endpoint number will be
                  used as the channel number.
