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 Previous versions of this patch-set can be found here: v2: https://lore.kernel.org/linux-media/20231207052016.25954-1-zhi.mao@xxxxxxxxxxxx/ v1: https://lore.kernel.org/linux-media/20231123115104.32094-1-zhi.mao@xxxxxxxxxxxx/ This series is based on linux-next, tag: next-20240108 Changes in v3: - dts-binding files： -- rename enable-gpio to reset-gpio. -- remove "status","clock-names" & "clock-frequency" useless infomatin in dts-binding files. -- remove the modifcation in "vendor-prefixes.yaml" as key words “galaxycore” has been added. - gc08a sensor driver： -- rename enable-gpio to reset-gpio in sensor driver -- remove reset-gpio pull low in start of function：power_on() -- fix some indentation code style issue in sensor driver probe function -- remove some dev_info() print log function and some none C style comments in sensor driver -- remove system suspend/resume operations and implement runtime PM support -- remove .g_volatile_ctrl() and .try_ctrl() implementations -- revome g_register/s_register functions -- remove "mutex" cntrol and use subdev active state -- remove "fmt&crop" variable in sensor driver and let subdev active state to store them -- use v4l2-cci api to read/write sensor register -- remove some dependencies & selection infomation in Kconfig, as they are handled in the VIDEO_CAMERA_SENSOR menu -- remove .try_ctrl callback function -- remobe "streaming == enable" in start_stream function -- use an exact match method in enum_frame_interval() function -- add "V4L2_SUBDEV_FL_HAS_EVENTS" for sd.flags in probe() function Thanks Zhi Mao (2): media: dt-bindings: media: i2c: Document GC08A3 bindings media: i2c: Add GC08A3 image sensor driver .../bindings/media/i2c/galaxycore,gc08a3.yaml | 112 ++ drivers/media/i2c/Kconfig | 10 + drivers/media/i2c/Makefile | 1 + drivers/media/i2c/gc08a3.c | 1467 +++++++++++++++++ 4 files changed, 1590 insertions(+) create mode 100644 Documentation/devicetree/bindings/media/i2c/galaxycore,gc08a3.yaml create mode 100644 drivers/media/i2c/gc08a3.c -- 2.25.1
