The Allwinner A10 Display pipeline is composed of several components
that are going to be documented below:
For the input port of all components up to the TCON in the display
pipeline, if there are multiple components, the local endpoint IDs
must correspond to the index of the upstream block. For example, if
the remote endpoint is Frontend 1, then the local endpoint ID must
be 1.
Conversely, for the output ports of the same group, the remote endpoint
ID must be the index of the local hardware block. If the local backend
is backend 1, then the remote endpoint ID must be 1.

The output should have two endpoints. The first is the block
connected to the TCON channel 0 (usually a panel or a bridge), the
second the block connected to the TCON channel 1 (usually the TV
encoder)
The output may have multiple endpoints. The TCON has two 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.). The endpoints
will take an extra property, allwinner,tcon-channel, to specify the
channel the endpoint is associated to. If that property is not
present, the endpoint number will be used as the channel number.
