Subject: [PATCH v2 00/16] media: i2c: Miscellaneous features and fixes for
 OV5647

This series adds support for some important features, like controls for
H/VFLIP, horizontal blanking, link frequency and regulator support that
is present in the downstream kernel to support the Raspberry Pi v1 camera
module.

Additionally, it also fixes some known issues with streaming lockups and
wrong pixel array size.

Changes in v2:
- Drop [PATCH 4/13] as it is already present in mainline
- Add a fix for a potential segfault by reordering ov5647_init_controls
  after v4l2_i2c_subdev_init in the probe
- Add 2 new patches updating dt-bindings for regulators and
  rotation/orientation
- Add a patch for cleaning up the PIXEL_RATE control
- Reorder the patches in the series, moving all fixes at the start
- Fix review comments from Jacopo, Stefan, Kieran and Dave, picking
  Jacopo's R-by tag on a few patches
- Link to v1: https://lore.kernel.org/r/20251028-b4-rpi-ov5647-v1-0-098413454f5e@ideasonboard.com
