Subject: [PATCH v2 0/5] Add support for DCMIPP camera interface of STMicroelectronics STM32 SoC series
Date: Tue, 29 Aug 2023 15:23:44 +0200 [thread overview]
Message-ID: <20230829132357.192535-1-alain.volmat@foss.st.com> (raw)
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
