[PATCH v3 00/11] media: ov772x: support media controller, device tree probing, etc.

[Akinobu Mita <akinobu.mita@gmail.com>]

This patchset includes support media controller, sub-device interface,
device tree probing and other miscellanuous changes for ov772x driver.

* v3 (thanks to Sakari Ailus and Jacopo Mondi)
- Reorder the patches
- Add Reviewed-by: lines
- Remove I2C_CLIENT_SCCB flag set as it isn't needed anymore
- Fix typo in the commit log
- Return without resetting if ov772x_edgectrl() failed
- Update the error message for missing platform data
- Rename mutex name from power_lock to lock
- Add warning for duplicated s_power call
- Add newlines before labels
- Remove __v4l2_ctrl_handler_setup in s_power() as it causes duplicated
  register settings
- Make set_fmt() return -EBUSY while streaming (New)

* v2 (thanks to Jacopo Mondi)
- Replace the implementation of ov772x_read() instead of adding an
  alternative method
- Assign the ov772x_read() return value to pid and ver directly
- Do the same for MIDH and MIDL
- Move video_probe() before the entity initialization and remove the #ifdef
  around the media_entity_cleanup()
- Use generic names for reset and powerdown gpios (New)
- Add "dt-bindings:" in the subject
- Add a brief description of the sensor
- Update the GPIO names
- Indicate the GPIO active level
- Add missing NULL checks for priv->info
- Leave the check for the missing platform data if legacy platform data
  probe is used.
- Handle nested s_power() calls (New)
- Reconstruct s_frame_interval() (New)
- Avoid accessing registers
