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

v3:
  - Have same To & Cc in all patches emails of the serie so that everybody
    has coherent view of the serie
  - bindings: correct wording, clock-names & label removal
  - driver: replace of_graph call with fwnode_graph
  - driver: use defined bus-type when calling v4l2_fwnode_endpoint_parse
  - driver: remove clock name
  - dtsi: remove clock-names property

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
