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 Alain Volmat (2): dt-bindings: media: add bindings for dcmipp driver media: MAINTAINERS: add entry for STM32 DCMIPP driver Hugues Fruchet (3): media: stm32-dcmipp: STM32 DCMIPP camera interface driver ARM: dts: stm32: add dcmipp support to stm32mp135 ARM: multi_v7_defconfig: enable STM32 DCMIPP media support .../bindings/media/st,stm32-dcmipp.yaml | 95 ++ MAINTAINERS | 9 + arch/arm/boot/dts/st/stm32mp135.dtsi | 9 + arch/arm/configs/multi_v7_defconfig | 1 + drivers/media/platform/st/stm32/Kconfig | 15 + drivers/media/platform/st/stm32/Makefile | 1 + .../platform/st/stm32/stm32-dcmipp/Makefile | 5 + .../st/stm32/stm32-dcmipp/dcmipp-bytecap.c | 1040 +++++++++++++++++ .../st/stm32/stm32-dcmipp/dcmipp-byteproc.c | 692 +++++++++++ .../st/stm32/stm32-dcmipp/dcmipp-common.c | 105 ++ .../st/stm32/stm32-dcmipp/dcmipp-common.h | 227 ++++ .../st/stm32/stm32-dcmipp/dcmipp-core.c | 673 +++++++++++ .../st/stm32/stm32-dcmipp/dcmipp-parallel.c | 523 +++++++++ 13 files changed, 3395 insertions(+) create mode 100644 Documentation/devicetree/bindings/media/st,stm32-dcmipp.yaml create mode 100644 drivers/media/platform/st/stm32/stm32-dcmipp/Makefile create mode 100644 drivers/media/platform/st/stm32/stm32-dcmipp/dcmipp-bytecap.c create mode 100644 drivers/media/platform/st/stm32/stm32-dcmipp/dcmipp-byteproc.c create mode 100644 drivers/media/platform/st/stm32/stm32-dcmipp/dcmipp-common.c create mode 100644 drivers/media/platform/st/stm32/stm32-dcmipp/dcmipp-common.h create mode 100644 drivers/media/platform/st/stm32/stm32-dcmipp/dcmipp-core.c create mode 100644 drivers/media/platform/st/stm32/stm32-dcmipp/dcmipp-parallel.c
