143 first channel being used for the panels interfaces
144 (RGB, LVDS, etc.), and the second being used for the
145 outputs that require another controller (TV Encoder,
146 HDMI, etc.).
147
148 If that property is present, specifies the TCON
149 channel the endpoint is associated to. If that
150 property is not present, the endpoint number will be
151 used as the channel number.
