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: 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-20240202 Changes in v4: - dts-binding files： -- rename the titile of patch "dt-bindings" -- use "sensor@31" as device node,according to Krzysztof's suggestion - gc08a sensor driver： -- use "ARRAY_SIZE(...)" directly in driver code, instead of macros -- use pointer to corresponds an array entry of link_frequency -- use variable of struc "mode" in function:gc08a3_get_selection() -- declare ret as last in function:gc08a3_test_pattern() -- fix some coding style by "checkpatch.pl --strict --max-line-length=80" -- remove function:gc08a3_g_mbus_config() -- use "v4l2_link_freq_to_bitmap()" API to parse driver-supported link frequencies -- move runtime PM API before registering the sub-device 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 | 1448 +++++++++++++++++ 4 files changed, 1571 insertions(+) create mode 100644 Documentation/devicetree/bindings/media/i2c/galaxycore,gc08a3.yaml create mode 100644 drivers/media/i2c/gc08a3.c -- 2.25.1
