[PATCH v4 0/4] media: i2c: Add OX05B1S camera sensor driver

[Mirela Rabulea <mirela.rabulea@nxp.com>]

Add a v4l2 subdevice driver for the Omnivision OX05B1S RGB-IR sensor

The Omnivision OX05B1S is a 1/2.5-Inch CMOS image sensor with an active array size
of 2592 x 1944.
    
The following features are supported for OX05B1S:
   - Manual exposure an gain control support
   - vblank/hblank control support
Supported resolution:
   - 2592 x 1944 @ 30fps (SGRBG10)

Support for another sensor, OS08A20, is added as a separate patch, using another compatible.
For OS08a20, HDR mode control is supported, with one HDR mode: staggered HDR with 2 exposures on separate virtual channels. However, for now, only one exposure (VC 0) is accessible via get_frame_desc.

Supported resolutions:
   - 1920 x 1080 @ 60fps (SBGGR10, no HDR)
   - 1920 x 1080 @ 30fps (SBGGR10, HDR)
   - 3840 x 2160 @ 30fps (SBGGR12, no HDR)
   - 3840 x 2160 @ 15fps (SBGGR12, HDR)
   - 3840 x 2160 @ 30fps (SBGGR10, no HDR)
   - 3840 x 2160 @ 15fps (SBGGR10, HDR)

The driver was tested on upstream 6.14-rc2 on imx8mp-evk, but also on nxp tree based on 6.12 on imx95-19x19-evk.

The results of v4l2-compliance test:
