Subject: [RFC PATCH v2 0/2] [media] tvp515p: Proposal for MC input connector support

Hello,

This is a second version of an RFC patch series that adds MC input connector
support to the tvp5150 driver. The first RFC version was [0].

The patches are RFC because a previous version was merged and later reverted
since the approach was found to be inadequate. So I preferred to post this
approach as RFC to discuss it first.

The main difference with v1 is that a single sink pad is used for the tvp5150
(instead of using a pad per each input pin) as suggested by Mauro and Hans.

The mc_nextgen_test dot output after applying the series can be found at [1]
and the graph png generated using the dot tool is at [2].

I tested these patches on an IGEPv2 by capturing using both Composite inputs.

Best regards,

Changes in v2:
- Remove from the changelog a mention of devices that multiplex the
  physical RCA connectors to be used for the S-Video Y and C signals
  since it's a special case and it doesn't really work on the IGEPv2.
- Use a single sink pad for the demod and map the connectors as entities
  so the mux is made via links. Suggested by Mauro and Hans.
