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.
