Hello,

This series adds DT binding and driver for Omnivision's OV02A10 2 megapixel CMOS 1/5" sensor,
which has a single MIPI lane interface and output format of 10-bit RAW.

The driver is implemented wth V4L2 framework.
1. Async registered as a V4L2 I2C sub-device.
2. The first component of camera system including Seninf, ISP.
3. A media entity that can provide one source pad in common and two for dual camera.

Changes compared to v5:
 - Rebase onto 5.5-rc1
 - Remove the handler of "ovti, hs-vod-adjust" property
 - Define new macro HZ_PER_MHZ to describe frequency-related parameters
 - Fixup coding style and improve code quality
 - Fix other reviewed issues in v5

Changes of v5 are addressing comments from Sakari, Tomasz.
 - Set default orientation in dt-bindings
 - Move the content of power on/off directly to the resume/suspend callbacks
 - Move sensor id check to power on to avoid the privacy LED flash on boot
 - Remove unnecessary debug log in driver
 - Fix other reviewed issues in v4

Changes of v4 mainly address the comments from Sakari, Rob, Tomasz.
 - Remove data-lanes property in DT
 - Add link frequencies in DT to match the expect value that driver requires
 - Omit open callback as int_cfg is implemented
 - Use i2c_smbus_write_byte_data/i2c_smbus_read_byte_data instead of customed APIs
 - Use do_div to calculate pixel rate
 - Use usleep_range directly for shoter sleep case
 - Re-adjust sensor power up/off sequence
 - Re-set pd/rst GPIO inverter property according to the datasheet
 - Refine set_exposure/set_gain/set_vblanking/set_test_pattern functions
 - Fix other reviewed issues in v3

Changes of v3 are mainly addressing comments from Rob, Sakari, Bingbu.
 - Fix coding style errors in dt-bindings
 - Use macro flag to describle basic line 1224 when updating v-blanking
 - Remove unnecessary debug log in driver

Mainly changes of v2 are addressing the comments from Nicolas, Bingbu, Sakari, Rob,
including,
 - Put dt binding before driver in series
 - Add MAINTAINERS entries
 - Squash the MAINTAINERS entry and Kconfig to driver patch
 - Add rotation support for driver
 - Fix other reviewed issues in v1
