[PATCH v7 0/3] media: i2c: Add OmniVision OG0VA1B camera sensor driver

[Wenmeng Liu <wenmeng.liu@oss.qualcomm.com>]

Add OmniVision OG0VA1B driver support. The OmniVision OG0VA1B is a
1/10-inch monochrome CMOS VGA image sensor. It outputs 10-bit raw (Y10)
frames at up to 640x480 resolution over a single-lane MIPI CSI-2
interface and is controlled via an I2C-compatible SCCB bus.

This driver has been verified(include tpg) on the Purwa EVK.

Changes in v7:
- Drop the test pattern rename patch. As Sakari noted, a monochrome
colour filter does not imply the internal TPG cannot generate colour
patterns, so the original "Vertical Colour Bars" name is kept. -- Sakari
- Give the control registers shared by both sensors (mode select,
software reset, exposure, analogue gain, vertical timing and the test
pattern enable bit) a common OG0V_ prefix; part-specific registers keep
their per-sensor prefix. -- Sakari
- Reorder struct og0ve1b_sensor_data members to avoid padding. -- Sakari
- Link to v6: https://lore.kernel.org/r/20260901-og0va1b-v6-0-a05b2d04c892@oss.qualcomm.com

Changes in v6:
- Rebased onto v7.3-rc1 and added the Vladimir`s Reviewed-by tag for Patch 2.
- Link to v5: https://lore.kernel.org/all/20260731-og0va1b-v5-0-c2b90b601241@oss.qualcomm.com/

Changes in v5:
- Use div_u64() for pixel rate calculation to avoid 64-bit division
helpers on 32-bit architectures. -- sashiko-bot, kernel test robot
- Link to v4: https://lore.kernel.org/r/20260729-og0va1b-v4-0-ec7e7ed87b2b@oss.qualcomm.com

Changes in v4:
- Rename the OG0VA1B and OG0VE1B test pattern menu entries to make them 
more accurate. -- Vladimir
- Link to v3: https://lore.kernel.org/r/20260708-og0va1b-v3-0-de8e44455a42@oss.qualcomm.com

Changes in v3:
- Generalise the binding title and description for both sensors. -- Vladimir
- Keep the cached pre_isp read so the OG0VE1B test pattern still works,
select it via a per-sensor callback. -- Bryan, Vladimir
- Rename the "sensor" field to "data", drop bpp (derive from code) and
add og0ve1b_pixel_rate(). -- Vladimir
- Sort defines, rename the shared CHIP_ID reg to OG0V_ and order
og0va1b_data first. -- Vladimir
- Expose all four OG0VA1B test patterns instead of one.
- Link to v2: https://lore.kernel.org/r/20260702-og0va1b-v2-0-0071442caa2a@oss.qualcomm.com

Changes in v2:
- Integrate OG0VA1B into the existing og0ve1b driver and binding
instead. -- Vladimir
- Link to v1: https://lore.kernel.org/r/20260618-og0va1b-v1-0-dda71bb83009@oss.qualcomm.com
