Add a v4l2 subdevice driver for the Sony IMX283 image sensor. The IMX283 is a 20MP Diagonal 15.86 mm (Type 1) CMOS Image Sensor with Square Pixel for Color Cameras. The following features are supported: - Manual exposure an gain control support - vblank/hblank/link freq control support - Test pattern support control - Arbitrary horizontal and vertical cropping - Supported resolution: - 5472x3648 @ 20fps (SRGGB12) - 5472x3648 @ 25fps (SRGGB10) - 2736x1824 @ 50fps (SRGGB12) The driver is tested on mainline branch v6.8-rc2 on IMX8MP Debix-SOM-A. Additional testing has been done on RPi5 with the downstream BSP. Changes in v4: - fix 32-bit build error around u64 divisions (use do_div) - Fix hmax default and minimum values Changes in v3: - fix headers includes - Improve #define(s) readability - Drop __func__ from error logs - Use HZ_PER_MHZ instead of MEGA - mdsel* variables should be u8 - Use container_of_const() instead of container_of() - Use clamp() used of clamp_t variant - Use streams API imx283_{enable|disable}_streams (**NOTE**) - Properly fix PM runtime handling (pm_ptr(), DEFINE_RUNTIME_DEV_PM_OPS, imx283_runtime_suspend, imx283_runtime_resume) - Fix format modifiers, signed-ness at various places changes in v2 (summary): - Use u32 wherever possible - Use MEGA macro instead of self defined MHZ() macro - Properly refine regs using CCI - Drop tracking of current mode. Shifted to infer from active state directly. (Laurent's review) - Cont. from above: Pass the struct imx283_mode to functions whereever required. - Remove unused comments - Remove custom mutex. Use control handler one instead. - Drop imx283_reset_colorspace() and inline - Set colorspace field properly (drop _DEFAULTS) - Use __maybe_unused for imx283_power_on() and imx283_power_off() - Store controls v4l2_ctrl handles for those required, not all. - Drop imx283_free_controls(). Use v4l2_ctrl_handler_free - fix reset-gpios handling and add it to DT schema - fix data-lanes property in DT schema - fix IMX283 Kconfig - Remove unused macros - Alphabetical case consistency Signed-off-by: Umang Jain <umang.jain@xxxxxxxxxxxxxxxx> --- Kieran Bingham (1): media: i2c: Add imx283 camera sensor driver Umang Jain (1): media: dt-bindings: media: Add bindings for IMX283 .../devicetree/bindings/media/i2c/sony,imx283.yaml | 107 ++ MAINTAINERS | 9 + drivers/media/i2c/Kconfig | 10 + drivers/media/i2c/Makefile | 1 + drivers/media/i2c/imx283.c | 1605 ++++++++++++++++++++ 5 files changed, 1732 insertions(+) --- base-commit: 54ee11761885407056f4ca60309739e2db6b02dc change-id: 20240402-kernel-name-extraversion-2b08d441e08c Best regards, -- Umang Jain <umang.jain@xxxxxxxxxxxxxxxx>
