media: staging: media: rkisp1: make links immutable by default
The only places which make sese to allow users to enable or disable
links are:
* between sensors and isp:
So users can select which sensor should be used while streaming
* between isp and the resizers:
|
v here
rkisp1_isp:2 -> rkisp1_resizer_mainpath -> rkisp1_mainpath (capture)
\-> rkisp1_resizer_selfpath -> rkisp1_selfpath (capture)
^ here
|
So users can disable one of the capture paths when unused, to avoid
worring about matching formats.
Make the following links immutable to simplify userspace:
rkisp1_resizer_mainpath -> rkisp1_mainpath
rkisp1_resizer_selfpath -> rkisp1_selfpath
rkisp1_params -> rkisp1_isp
rkisp1_isp -> rkisp1_stats
