[RFC PATCH 0/3] [media] tvp515p: Proposal for MC input connector support

[Javier Martinez Canillas <javier@osg.samsung.com>]

Hello,

I was waiting for the MC input connector support discussion to settle before
attempting to propose another patch series for the tvp5150 video decoder but
IIUC you are going to continue the discussion at ELC so I'm posting a series
that I believe is aligned with the latest conversations.

This is of course a RFC and not meant to be merged but just to start looking
how the DT binding using OF graph for connectors could look like and to see
an implementation that uses a PAD (and thus link) per electrical signal (the
1:1 model mentioned by Laurent).

The mc_nextgen_test dot output after applying the series can be found at [0]
and the graph png generated using the dot tool at [1].

I've also uploaded the dot files and png when the Composite0 [2,3], Composite1
[4,5] and S-Video [6,7] links are enabled.

I tested these patches on an IGEPv2 by capturing using both Composite inputs,
unfortuantely S-Video using the two RCA connectors is not working, but seems
that is a regression with the tvp5150 driver not related with these patches.
