[PATCH v5 0/2] media: i2c: Add support for GC08A3 sensor

[Zhi Mao]

This series adds YAML DT binding and V4L2 sub-device driver for Galaxycore's
GC08A3 8-megapixel 10-bit RAW CMOS 1/4" sensor, with an MIPI CSI-2 image data
interface and the I2C control bus.

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.
 - Used in camera features on ChromeOS application.

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: 3264x2448@30fps, 1920x1080@60fps

Changes in v5:
- gc08a3 sensor driver：
-- sort the header files alphabetically in driver code
-- refine the register define and some macros, fix some typo 
-- drop variable：“clinet/streaming” in struct gc08a3
-- refine "ret" flow in function:gc08a3_test_pattern()
-- drop the gc08a3_link_freq_config structure
-- rename some function and variable with a "gc08a3_" prefix
-- refine function:gc08a3_identify_module()/gc08a3_power_on()/gc08a3_power_off()/gc08a3_update_pad_format()
-- use stored crop rectangle in funcion:gc08a3_get_selectoin()
-- use cci_update_bits() in function:gc08a3_set_ctrl_hflip()/gc08a3_set_ctrl_vflip()
-- put the HFLIP and VFLIP controls in a cluster to make it efficiently set in an atomic operation
-- use "fwnode_graph_get_endpoint_by_id" in function: gc08a3_parse_fwnode()
-- remove function:gc08a3_enum_frame_interval()
-- enable autosuspend in function:probe()

Thanks
