-Subject: [PATCH] media: i2c: imx477: Support for the Sony IMX477
- sensor
-
-dt-bindings: media: i2c: Add IMX477 CMOS sensor binding
-
-Add YAML device tree binding for IMX477 CMOS image sensor.
-

-
-media: i2c: Add driver for Sony IMX477 sensor
-
-Adds a driver for the 12MPix Sony IMX477 CSI2 sensor.
-Whilst the sensor supports 2 or 4 CSI2 data lanes, this driver
-currently only supports 2 lanes.
-
-The following Bayer modes are currently available:
-
-4056x3040 12-bit @ 10fps
-2028x1520 12-bit (binned) @ 40fps
-2028x1050 12-bit (cropped/binned) @ 50fps
-1012x760 10-bit (scaled) @ 120 fps
-

-media: i2c: imx477: Add support for adaptive frame control
-
-Use V4L2_CID_EXPOSURE_AUTO_PRIORITY to control if the driver should
-automatically adjust the sensor frame length based on exposure time,
-allowing variable frame rates and longer exposures.
-

-the expected sensor id.

-media: i2c: imx477: Selection compliance fixes
-
-To comply with the intended usage of the V4L2 selection target when
-used to retrieve a sensor image properties, adjust the rectangles
-returned by the imx477 driver.
-
-The top/left crop coordinates of the TGT_CROP rectangle were set to
-(0, 0) instead of (8, 16) which is the offset from the larger physical
-pixel array rectangle. This was also a mismatch with the default values
-crop rectangle value, so this is corrected. Found with v4l2-compliance.
-
-While at it, add V4L2_SEL_TGT_CROP_BOUNDS support: CROP_DEFAULT and
-CROP_BOUNDS have the same size as the non-active pixels are not readable
-using the selection API. Found with v4l2-compliance.
-
-This commit mirrors 543790f777ba1b3264c168c653db6d415e7c983f done for
-the imx219 sensor.

-media: i2c: imx477: Remove auto frame length adjusting
-
-The V4L2_CID_EXPOSURE_AUTO_PRIORITY was used to let the sensor control
-frame length (effectively framerate) based on the requested exposure
-time requested. Remove this feature as it is never used, and goes
-against how V4L2 likes to handle exposure and vblank controls.

-
-media: i2c: imx477: Add very long exposure control to the driver
-
-Add support for very long exposures by using the exposure multiplier
-register. Userland does not need to pass any additional controls to
-enable long exposures, it simply requests a larger vblank to extend the
-exposure control range appropriately.
-
-Currently, since hblank is fixed, a maximum of approximately 124 seconds
-of exposure time can be used. In a future change, hblank could also be
-controlled in userland to give over 200 seconds of exposure time.

-
-The existing 1012x760 120 fps mode has significant IQ problem using
-the internal sensor scaler. Replace this mode with a 1332x990 120 fps
-mode instead. This new mode has a smaller field of view, but does not
-suffer from the bad IQ of the original mode.

-media: i2c: imx477: Remove internal v4l2_mbus_framefmt from the state
-
-The only field in this struct that is used is the format code, so
-replace the struct with this single field.
-
-Save the format code in imx477_set_pad_format() when setting up a new
-mode so that imx477_get_pad_format() performs the right lookup.
-Otherwise, this caused a bug where the mode lookup occurred on the
-12-bit table rather than the 10-bit table.

-
-media: i2c: imx477: Fix for long exposure limit calculations
-
-Do not scale IMX477_EXPOSURE_OFFSET with the long exposure factor during

-what the sensor is doing internally.

-This is a global setting to be configured before using the sensor;

-preserves any manual control values the user might have set.
