Subject: [PATCH v4 0/2] media: i2c: Add support for GC05A2 sensor

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@...ps, 1280x720@...ps

v0:https://lore.kernel.org/linux-media/20240313054409.8073-1-zhi.mao@mediatek.com/

This series is based on linux-next, tag: next-20240426
Changes in v4:
- gc05a2 sensor driver：
-- remove pm_runtime_set_active() in function:probe(), as there is no sensor power on operation in probe process
-- add comments for default case pattern index
-- remove some obscure register comments
-- use decimal unit for width register setting

Thanks
