[PATCH v3 0/2] media: i2c: Add support for GC05A2 sensor

[Zhi Mao]

This series adds YAML DT binding and V4L2 sub-device driver for Galaxycore's
GC05A2 5-megapixel 10-bit RAW CMOS 1/5" 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: 2592x1944@30fps, 1280x720@60fps

Changes in v3:
- gc05a2 sensor driver:
-- remove gc05a2_power_on() in function:probe(),
   and use pm_runtime_resume_and_get() to power on sensor in function:start_streaming()
-- move gc05a2_identify_module() frome function:probe() to function:start_streaming()
