Replace previous patch adding paths and SerDes modes with patch series pending upstream adding dedicated drivers for XFI T-PHY and USXGMII PCS, extends LynxI PCS to be a standalone platform driver and as a consequence makes much less changes to the actual Ethernet driver mtk_eth_soc.

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

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: 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.

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 only field in this struct that is used is the format code, so

Save the format code in imx477_set_pad_format() when setting up a new
