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 v8: - serie rebased on top of master branch of tree sailus/media_tree.git in order to use v4l2_subdev_state_* functions v7: - correct byteproc set_fmt handling and compose/crop/fmt handling - replace few v4l2_subdev_get_try_* into v4l2_subdev_get_pad_* - correct ordering within dcmipp_remove v6: - correct copyright year in all files - correct Kconfig (removal of OF addition of select VIDEO_V4L2_SUBDEV_API/MEDIA_CONTROLLER - add missing mutex_destroy in error handling - rely on fwnode_graph_get_endpoint_by_id instead of fwnode_graph_get_next_endpoint - rely on device_get_match_data instead of of_device_get_match_data - use local variable for pads_flag initialization v5: - removal of dcmipp_frame_size & dcmipp_frame_stride and use v4l2_fill_pixfmt - correct typos & avoid check of available buffer at start_streaming time since this is done by vb2 framework - avoid set of pad format in dcmipp_par_ent_init and dcmipp_byteproc_ent_init since done via init_cfg - reorder bound functions - use v4l2_subdev_get_fmt in parallel and byteproc subdevs - correct struct dcmipp_ent_device comments - removal of dcmipp_hdw_pixel_alignment in bytecap subdev since not applicable in this byte mode pipeline v4: - rework of mutex / spinlock handling - addition of dma mask setting - removal of __maybe_unused, use pm_ptr and new declaration macros - driver now only generate a single stm32-dcmipp.ko module instead of several as before - removal of the component framework usage - various small fixes (function names, lowercase values, indentation, print formats) - register name removal in register access function, only dev_dbg with address & values are kept - removal of VB2_READ and CAP_READWRITE - usage of subdev active state mechanism and removal of locally stored format/compose/crop - addition of port { } within the stm32mp135.dtsi 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 Alain Volmat (2): dt-bindings: media: add bindings for stm32 dcmipp 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 | 89 ++ MAINTAINERS | 5 +- arch/arm/boot/dts/st/stm32mp135.dtsi | 11 + arch/arm/configs/multi_v7_defconfig | 1 + drivers/media/platform/st/stm32/Kconfig | 16 + drivers/media/platform/st/stm32/Makefile | 1 + .../platform/st/stm32/stm32-dcmipp/Makefile | 4 + .../st/stm32/stm32-dcmipp/dcmipp-bytecap.c | 914 ++++++++++++++++++ .../st/stm32/stm32-dcmipp/dcmipp-byteproc.c | 565 +++++++++++ .../st/stm32/stm32-dcmipp/dcmipp-common.c | 106 ++ .../st/stm32/stm32-dcmipp/dcmipp-common.h | 216 +++++ .../st/stm32/stm32-dcmipp/dcmipp-core.c | 604 ++++++++++++ .../st/stm32/stm32-dcmipp/dcmipp-parallel.c | 440 +++++++++ 13 files changed, 2971 insertions(+), 1 deletion(-) 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
