From: Sebastian Reichel <sebastian.reichel@xxxxxxxxxxxxx> Hi, I did the following tests on an i.MX6ULL based system [0]: * v4l2-compliance -u /dev/v4l-subdev1 - v4l2-compliance 1.26.0, 32 bits, 32-bit time_t (from Debian testing) - Total for device /dev/v4l-subdev1: 45, Succeeded: 45 * Using gstreamer + v4l2-ctl - Tried 640x480, 320x240, 160x120 YUYV8_2X8 formats - Tested effect of all exposed user controls * checkpatch does not report any driver issues * dt_binding_check does not report anything * rebind driver works [0] https://embedded-recipes.org/2023/schedule/running-foss-thermal-camera/ Changes since PATCHv4: * https://lore.kernel.org/all/20231113230421.226808-1-sre@xxxxxxxxxx/ * Rebase to latest master branch from Sakari - v4l2_subdev_get_pad_format -> v4l2_subdev_state_get_format - v4l2_subdev_get_try_format -> v4l2_subdev_state_get_format - v4l2_subdev_pad_ops.init_cfg -> v4l2_subdev_internal_ops.init_state * Fix feedback from Tommaso Merciai - uint8_t -> u8 - drop extra newline - introduce gc0308_init_controls * Drop galaxycore vendor binding (merged) * Drop async fixes (merged to different tree) Changes since PATCHv3: * https://lore.kernel.org/all/20231027011417.2174658-1-sre@xxxxxxxxxx/ * Rebased to v6.7-rc1 * Replace gc0308_is_valid_format() with gc0308_get_format_idx(), which can be reused in gc0308_set_format(). * Remove the runtime PM get call in remove function * Move the runtime PM get call before the subdev register call in probe * Drop message about unsupported format code * Add Reviewed-by: Jacopo Mondi <jacopo.mondi@xxxxxxxxxxxxxxxx> * Merged binding patch with the one from Alain Volmat and add Acked-by: Rob Herring <robh@xxxxxxxxxx> and assign authorship to him, since his patch arrived first on the ML * Added two patches to fix an issue with v4l2_async_unregister_subdev() list handling Changes since PATCHv2: * https://lore.kernel.org/all/20231024010355.1877523-1-sre@xxxxxxxxxx/ * Simplify Kconfig dependencies * Do not store code/resolution; which is available from subdev state * Store register values for mode settings to avoid second lookup in s_stream * Reduce power_on sleep times * remove debug dev_err() print, that I accidently added in v2 * add missing format check in gc0308_enum_frame_size() * do not PM resume in gc0308_s_ctrl() * enable and use runtime PM autosuspend * add .init_cfg() PAD op * use CCI helper instead of raw regmap * cluster both flip controls (that's not just a performance optimization, but fixes an issue, that register update is slow, so fast sequential setting of VFLIP/HFLIP override each other without this) * simplify gc0308_set_power_line_freq * free control handler on probe error * use first format by default * expose V4L2_CID_HBLANK, V4L2_CID_VBLANK, V4L2_CID_PIXEL_RATE * remove incorrect support for framerate and instead add a comment Changes since PATCHv1: * https://lore.kernel.org/all/20231023002547.1754190-1-sre@xxxxxxxxxx/ * Update binding: i2c0 -> i2c * Update binding: make GC0309 use GC0308 as fallback compatible * Add regulator handling in power_on/power_off * Fix alignment of regmap_multi_reg_write arguments * Fix useless extra return * Do not check for pad in gc0308_enum_frame_size() * Drop get_mbus_config implementation * Use V4L2_CID_AUTO_EXPOSURE_BIAS instead of V4L2_CID_EXPOSURE * Drop gc0308_get_format in favour of v4l2_subdev_get_fmt * Replace open-coded v4l2_find_nearest_size() logic * check clock rate instead of setting it * use fwnode_graph_get_endpoint_by_id() * power off device when probe errors out after power on * replace mutex with sub-device state * add Galaxycore to generic camera sensors section in MAINTAINERS * add GC0308 entry in MAINTAINERS Greetings, -- Sebastian Sebastian Reichel (3): media: dt-bindings: gc0308: add binding media: MAINTAINERS: Add GalaxyCore in camera sensor section media: i2c: gc0308: new driver .../bindings/media/i2c/galaxycore,gc0308.yaml | 108 ++ MAINTAINERS | 8 + drivers/media/i2c/Kconfig | 10 + drivers/media/i2c/Makefile | 1 + drivers/media/i2c/gc0308.c | 1451 +++++++++++++++++ 5 files changed, 1578 insertions(+) create mode 100644 Documentation/devicetree/bindings/media/i2c/galaxycore,gc0308.yaml create mode 100644 drivers/media/i2c/gc0308.c -- 2.42.0
