[PATCH v3 00/29] media: ov5647: Support RaspberryPi Camera Module v1

[Jacopo Mondi <jacopo@jmondi.org>]

Third iteration following:
v2: https://patchwork.linuxtv.org/project/linux-media/list/?series=3782
v1: https://patchwork.linuxtv.org/project/linux-media/list/?series=2765

Major changes are:
- Address Dave's comments
  - Remove superseded patch:
    "media: ov5647: Program mode only if it has changed"
  - Remove Raw Bayer pattern from mode names
  - Remove cosmetic re-flow of register-value tables

- Address Hans' comment:
  - Add support for V4L2_SEL_TGT_CROP_BOUNDS
  - Redefine the CROP rectangle relatively to the native pixel array as per
    "[PATCH 4/4] media: i2c: imx219: Selection compliance fixes"

- New patches:
  - media: ov5647: Support VIDIOC_SUBSCRIBE_EVENT
  Fix v4l2-compliance error:
  fail: v4l2-test-controls.cpp(823): subscribe event for control 'User Controls' failed

  - media: ov5647: Remove 640x480 SBGGR8 mode
  The 640x480 8-bit mode is broken, at least when capturing on RaspberryPi4.
  As the receiver works when capturing in 8-bit mode with other sensors, it
  might be legit to think the mode is broken. As I've no way to fix it, it's
  probably better to remove it completely.
