| |
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.

=========== = history = =========== version 4: - Also drop subdev nodes registry as suggested by Hans: https://www.spinics.net/lists/arm-kernel/msg743375.html
version 3: - Drop media device registry to not expose media controller interface to userspace as per Laurent' suggestion: https://www.spinics.net/lists/linux-media/msg153417.html - Prefer "source" instead of "sensor" and keep it in dcmi_graph_entity struct, move asd as first member of struct as per Sakari' suggestion: https://www.spinics.net/lists/linux-media/msg153119.html - Drop dcmi_graph_deinit() as per Sakari' suggestion: https://www.spinics.net/lists/linux-media/msg153417.html
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
