Hi,

this is the 4th series adding support for OV9281 which is quite similar to OV9282.
This includes:
* a small cleanup (Patch 1)
* adding a new compatible (Patch 2 & 3)
* adding support for regulators (Patch 4 & 5)
* Fixing v4l2 subdev name depending on actual model name (Patch 6)
* Add regmap support (Patch 7)

Thanks for anyone doing review and giving a feedback.

Here are the changes in v4:
* Use platform data to set sensor name (Patch 6)
* Fixed some style issues (Patch 7)

Here are the changes in v3:
* Removed struct field documentation as well (Patch 1)
* Dropped v2 Patch 6 (wrong approach)
* Added new Patch 6 to set subdev name according to model parsed form compatible
* Added new Patch 7 adding regmap support
  This is a preparation to solve the defunct auto-increment using regmap's
  'use_single_read' (still WIP)

Here are the changes in v2:
* Added Krzysztof's a-b for Patch 2 & 4
* Added Daniele's a-b for Patch 1 & 3
* Removed additional error message in ov9282_power_off
* Renamed function from ov9282_configure_regulators to ov9282_get_regulators
* Cleaned-up reading ID registers

The regulator support is based on the driver from Raspberry Pi downstream kernel
[1], the ID register read fix as well. Please refer to [2] why this fix is
required. I can confirm this is necessary by checking with a Logic analyzer on
the i2c bus.

Best regards,
Alexander
