Hello,

This series adds YAML DT binding and V4L2 sub-device driver for Omnivision's
OV02A10 2-megapixel 10-bit RAW CMOS 1/5" sensor, which has a single MIPI lane
interface and uses the I2C bus for control and the CSI-2 bus for data.

The driver is implemented with V4L2 framework.
 - Async registered as a V4L2 sub-device.
 - As the first component of camera system including Seninf, ISP pipeline.
 - A media entity that provides one source pad in common and two for dual-cam.

Also this driver supports following features:
 - Manual exposure and analog gain control support
 - Vertical blanking control support
 - Test pattern support
 - Media controller support
 - Runtime PM support
 - Support resolution: 1600x1200 at 30FPS

Changes of v14 mainly address comments from Tomasz and Sakari.
Compared to v13:
 - Fix imperfections in DT
 - Use an array property "ovti,mipi-clock-voltage" to indicate MIPI TX speed
 - Add the handler to the optional property "ovti,mipi-clock-voltage" in driver

Please help to review this patch.
Thanks.
