Subject[PATCH v2 0/5] Add support for DCMIPP camera interface of STMicroelectronics STM32 SoC series
Date
This patchset introduces support for Digital Camera Memory Interface
Pixel Processor (DCMIPP) of STMicroelectronics STM32 SoC series.

This initial support implements a single capture pipe
allowing RGB565, YUV, Y, RAW8 and JPEG capture with
frame skipping, prescaling and cropping.

DCMIPP is exposed through 3 subdevices:
- dcmipp_dump_parallel: parallel interface handling
- dcmipp_dump_postproc: frame skipping, prescaling and cropping control
- dcmipp_dump_capture: video device capture node

v2:
- removal of pclk-max-frequency from yaml example dts
- codying-style fixes
- correction in enum functions (format, mbus, frame_size ...) handling
- drop of v4l2_pipeline_pm_ calls, and specific open/close handler of
vdev
- video dev s_stream handling updated to call s_stream of remote subdev
instead of loop until sensor subdev
- code update following media_pipeline & v4l2_async_ api changes since v1
- removal of IP reset call upon error
- removal of link_validate handlers
- addition of V4L2_CAP_IO_MC device_caps
- removal of the frame skip control for the time being, will be added
back in another commit once control method will be agreed
- change byteproc entity type to MEDIA_ENT_F_PROC_VIDEO_SCALER
- various fixes from Dan & Sakari remarks
