Video Capture:
VPIF has a 16-bit parallel bus input, supporting 2 8-bit channels or a
single 16-bit channel. It should contain at least one port child node
with child 'endpoint' node. Please refer to the bindings defined in
single 16-bit channel. It should contain one or two port child nodes
with child 'endpoint' node. If there are two ports then port@0 must
describe the input and port@1 output channels. Please refer to the
bindings defined in
