v4:
- added Reviewed-by,
v3:
- removed clock-names,
- removed clock-frequency,
- added all-of of video-interface-devices schema,
- added clock frequency range in description,
- rephrased definition of supplies,
- fixed name of reset gpio,
- used schema ref for port and port->endpoint,
- removed mentions to driver,
- added HW data transfer speed limitation in comment for
link-frequencies,
- changed root additionalProperties to unevaluatedProperties to not
have to list all properties from video-interface-devices schema, such as
orientation or rotation,
- added maxItems to reset-gpios,
- updated example to use assigned-clocks and assigned-clock-rates
instead of clock-frequency and clock-names,
v2:
- fixed incorrect id,
- fixed device tree example by adding missing dt-bindings headers,
- fixed device tree example by using vcc_1v2 for dvdd supply, as requested
in datasheet,

+description: |
+ The Omnivision OV5675 is a high performance, 1/5-inch, 5 megapixel, CMOS
+ image sensor that delivers 2592x1944 at 30fps. It provides full-frame,
+ sub-sampled, and windowed 10-bit MIPI images in various formats via the
+ Serial Camera Control Bus (SCCB) interface.
+
+ This chip is programmable through I2C and two-wire SCCB. The sensor output
+ is available via CSI-2 serial data output (up to 2-lane).

Until now, this driver only supported ACPI. This adds support for
Device Tree too while enabling clock and regulators in runtime PM.

v4:
- added delays based on clock cycles as specified in datasheet for
pre-power-off and post-power-on,
- re-arranged clk handling, shutdown toggling and regulator handling to
better match power up/down sequence defined in datasheet,
- added comment on need for regulator being stable before releasing
shutdown pin,
v3:
- added linux/mod_devicetable.h include,
- moved delay for reset pulse right after the regulators are enabled,
- removed check on is_acpi_node in favor of checks on presence of OF
properties (e.g. devm_clk_get_optional returns NULL),
- moved power management out of system suspend/resume into runtime PM
callbacks,
- removed ACPI specific comment since it's not specific to this driver,
- changed devm_clk_get to devm_clk_get_optional,
- remove OF use of clock-frequency (handled by devm_clk_get_optional
directly),
- removed name of clock (only one, so no need for anything explicit)
when requesting a clock from OF,
- wrapped lines to 80 chars,
v2:
- fixed unused-const-variable warning by removing of_match_ptr in
of_match_table, reported by kernel test robot,

v4:
- explicit a bit more the commit log,
- added drawing in the commit log,
- fixed reporting for V4L2_SEL_TGT_CROP_* thanks to Jacopo's help,
added in v3
