Re: [PATCH v2 0/3] DCMI bridge support

Hi Hugues,

This patch serie allows to connect non-parallel camera sensor to
DCMI thanks to a bridge connected in between such as STMIPID02 [1].

Media controller support is introduced first, then support of
several sub-devices within pipeline with dynamic linking
between them.
In order to keep backward compatibility with applications
relying on V4L2 interface only, format set on video node
is propagated to all sub-devices connected to camera interface.

General notes on the set, not related to any single patch:

- Where's the sub-device representing the bridge itself?

- As the driver becomes MC-centric, crop configuration takes place through
  V4L2 sub-device interface, not through the video device node.

- Same goes for accessing sensor configuration: it does not take place
  through video node but through the sub-device nodes.
