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.
Signed-off-by: Naushir Patuck <naush@raspberrypi.com>
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
Signed-off-by: Naushir Patuck <naush@raspberrypi.com>
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.

media: i2c: imx477: Return correct result on sensor id verification
The test should return -EIO if the register read id does not match
the expected sensor id.

media: i2c: imx477: Parse and register properties
Parse device properties and register controls for them using the V4L2
fwnode properties helpers.

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.
Signed-off-by: Naushir Patuck <naush@raspberrypi.com>
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.

lines instead.

media: i2c: imx477: Replace existing 1012x760 mode
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: Remove unused function parameter
The struct imx477 *ctrl parameter is not used in the function
imx477_adjust_exposure_range(), so remove it.

media: i2c: imx477: Fix for long exposure limit calculations
Do not scale IMX477_EXPOSURE_OFFSET with the long exposure factor during
the limit calculations. This allows larger exposure times, and does seem to be
what the sensor is doing internally.

media: i2c: imx477: Extend driver to support imx378 sensor
The imx378 sensor is almost identical to the imx477 and can be

writes.

media: i2c: imx477: Fix framerates for 1332x990 mode
The imx477 driver's line length for this mode had not been updated to
the value supplied to us by the sensor manufacturer. With this
correction the sensor delivers the framerates that are expected.

media: i2c: imx477: Allow control of on-sensor DPC
A module parameter "dpc_enable" is added to allow the control of the
sensor's on-board DPC (Defective Pixel Correction) function.
This is a global setting to be configured before using the sensor;
there is no intention that this would ever be changed on-the-fly.

The minimum number of exposure lines value (IMX477_EXPOSURE_MIN) was
previously 20 but this is not correct. The datasheet is not completely
explicit, however the new value of 4 has been tested with all the
sensor modes supported by this driver, and matches the lowest exposure
value of 114us that could be achieved wtih Raspberry Pi's legacy
firmware driver.

media: i2c: imx477: Reset hblank on mode switch
Reset the hblank control to the minimum value on every mode switch. This is to

gets set to a non-optimal value.
Signed-off-by: Naushir Patuck <naush@raspberrypi.com>
media: i2c: imx477: Do not unconditionally adjust hblank and vblank limits
On a mode change, only call imx477_set_framing_limits() to adjust the hblank
and vblank limits if the new mode is different from the existing mode. This
preserves any manual control values the user might have set.
