-------------------------------------------------------------------------------

The smatch() warning reported here above:
drivers/media/i2c/ov64a40.c:3562 ov64a40_probe() warn: passing zero to 'PTR_ERR'
has been fixed.

v4->v5:
* Fix review comments received on RPi pull request (thanks Dave for review)
  https://github.com/raspberrypi/linux/pull/5708
* Handle runtime_pm in s_ctrl like it's done in CCS
* Add support for test patterns
* Add 8000x6000 mode
* Use decimal numbers in modes definitions

v3->v4:
* Fix a few additional warnings reported by kernel test robot (which arrived a
  few minutes after sending v3 out :(

v2->v3:
* Restore max size of 9248x6944
* Select V4L2_CCI_I2C in Kconfig
* Fix unused variable warning
* Fix a few minor checkpatch warnings

v1->v2:
* rebased on sailus master
  * Use new subdev state helpers
* link frequency support (456MHz, 360MHz)
* invert vflip bit setting
* remove 1280x720 mode as it was broken
* expanded VTS range to 24 bits
* Reduce max resolution output to 9152x6944. Using full output resolution causes
  green frames to be produced by the ISP (the raw frames are however correct)
* reduce max analogue gain to 16x
