[PATCH v6 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 v6:
- gc08a3 sensor driver：
-- refine header files in driver code
-- use macro HZ_PER_MHZ/USEC_PER_MSEC for some variable define
-- define reset-pin as active-low in DT,and use logical states: gpiod_set_value_cansleep(reset_gpio, 0) in driver
-- use new PM macros: pm_ptr()

Thanks
