[PATCH v5 0/2] OV5645 camera sensor driver

[Todor Tomov <todor.tomov@linaro.org>]

This is the fifth version of the OV5645 camera sensor driver patchset.

Two one-line changes since version 4:
- return current format on set_format;
- return all frame sizes when enumerating them.

Only one change since version 3:
- build failure on kernel v4.7-rc1 fixed:
  s/media_entity_init/media_entity_pads_init/

Changes from version 2 include:
- external camera clock configuration is moved from DT to driver;
- pwdn-gpios renamed to enable-gpios;
- switched polarity of reset-gpios to the more intuitive active low;
- added Kconfig dependency to OF;
- return values checks;
- regulators and gpios are now required (not optional);
- regulators names renamed;
- power counter variable changed to a bool power state;
- ov5645_registered() is removed and sensor id reading moved to probe().

Changes from version 1 include:
- patch split to dt binding doc patch and driver patch;
- changes in power on/off logic - s_power is now not called on
  open/close;
- using assigned-clock-rates in dt for setting camera external
  clock rate;
- correct api for gpio handling;
- return values checks;
- style fixes.
