[PATCH v2 2/2] media: i2c: add os02g10 image sensor driver

From: Elgin Perumbilly

Date: Tue Apr 14 2026 - 04:53:58 EST

Add a v4l2 subdevice driver for the Omnivision os02g10 sensor.

The Omnivision os02g10 is a CMOS image sensor with an active array size of
1920 x 1080.

The following features are supported:
- Manual exposure an gain control support
- vblank/hblank control support
- vflip/hflip control support
- Test pattern control support
- Supported resolution: 1920 x 1080 @ 30fps (SBGGR10)
