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: v4: https://lore.kernel.org/linux-media/20240204061538.2105-1-zhi.mao@xxxxxxxxxxxx/ v3: https://lore.kernel.org/linux-media/20240109022715.30278-1-zhi.mao@xxxxxxxxxxxx/ 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-20240219 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 Zhi Mao (2): media: dt-bindings: i2c: add GalaxyCore GC08A3 image sensor 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 | 1335 +++++++++++++++++ 4 files changed, 1458 insertions(+) create mode 100644 Documentation/devicetree/bindings/media/i2c/galaxycore,gc08a3.yaml create mode 100644 drivers/media/i2c/gc08a3.c -- 2.25.1
