Hi, This series adds a driver for the ST VGXY61 camera sensor. This camera sensor is using the i2c bus for control and the csi-2 bus for data. These commits introduce the MEDIA_BUS_FMT_Y16_1X16 as a media bus format (1/4), a standard control in V4L2 for the hdr mode (2/4), dt bindings (3/4), and the driver (4/4). Tested on DragonBoard 410c, Raspberry Pi 4, and Qualcomm Robotics RB5. Thanks, Benjamin v3->v4: - Standardize V4L2_CID_HDR_MODE - Refactor to 80 characters limit - Better types handling - Various others - Rebase on master v2->v3: - Fix errors in dt bindings - Use alphabetical order where applicable - Remove US_PER_MS macro - Rename device specific macros - Fix some control grabs not releasing - Move user controls to public header and add documentation - Rename set_framerate to set_framelength - Rework i2c access - Remove branchings that should never happen - Rework pattern generator setting - Update information on sensor rules of thumb - Remove temperature control - Remove suspend and resume - Move mutex init to probe - Move detect to probe - Fix async_subdev_register order - Support autosuspend - Add init_cfg - Fix controls not updating when sensor was off - Various cleaning - Rebase on master v1->v2: - Move temperature control to v4l2-controls.h as a standard control - Reserve controls in v4l2-controls.h for HDR control - Remove GPIO strobbing controls - Remove references to unused controls in sensor struct - Use v4l2_find_nearest_size - Use V4L2_COLORSPACE_RAW instead of V4L2_COLORSPACE_SRGB - Fill ycbcr_enc, quantization, and xfer_func in v4l2_mbus_framefmt - Change gain from formula to a register RAW write - Change temperature control value directly - Remove clock-name and clock-lanes from device tree bindings - Declare crop zones in mode_info structure - Remove frame_interval functions and add hblank and vblank instead - Update controls dependencies on change - Fix first exposure rule of thumb being too restrictive - Disable hflip and vflip controls while streaming - Change RGB media bus code to Y as the sensor is monochrome - Add Y16 format to v4l2 media bus formats - Add get_selection API - Fix timeout errors while disabling streaming on high framerates - Support pm_runtime - Rebase on master Benjamin Mugnier (4): media: v4l: Add 1X16 16-bit greyscale media bus code definition media: v4l: ctrls: Add a control for HDR mode media: dt-bindings: media: i2c: Add ST VGXY61 camera sensor binding media: i2c: Add driver for ST VGXY61 camera sensor .../bindings/media/i2c/st,st-vgxy61.yaml | 117 + .../media/v4l/ext-ctrls-camera.rst | 8 + .../media/v4l/subdev-formats.rst | 37 + MAINTAINERS | 9 + drivers/media/i2c/Kconfig | 10 + drivers/media/i2c/Makefile | 1 + drivers/media/i2c/st-vgxy61.c | 1967 +++++++++++++++++ drivers/media/v4l2-core/v4l2-ctrls-defs.c | 2 + include/uapi/linux/media-bus-format.h | 3 +- include/uapi/linux/v4l2-controls.h | 2 + 10 files changed, 2155 insertions(+), 1 deletion(-) create mode 100644 Documentation/devicetree/bindings/media/i2c/st,st-vgxy61.yaml create mode 100644 drivers/media/i2c/st-vgxy61.c -- 2.25.1
