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

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.

version 2:
  - Fix bus_info not consistent between media and V4L:
    https://www.spinics.net/lists/arm-kernel/msg717676.html
  - Propagation of format set on video node to the sub-devices
    chain connected on camera interface

version 1:
  - Initial submission

Hugues Fruchet (3):
  media: stm32-dcmi: improve sensor subdev naming
  media: stm32-dcmi: add media controller support
  media: stm32-dcmi: add support of several sub-devices
