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.
