The ov8865 driver as written expects a 24MHz input clock, but the sensor is sometimes found on x86 platforms with a 19.2MHz input clock supplied. Add a set of PLL configurations to the driver to support that rate too. As ACPI doesn't auto-configure the clock rate, check for a clock-frequency during probe and set that rate if one is found.

The ov8865 driver is one of those that can be connected to a CIO2 device by the cio2-bridge code. This means that the absence of an endpoint for this device is not necessarily fatal, as one might be built by the cio2-bridge when it probes. Return -EPROBE_DEFER if no endpoint is found rather than a fatal error. Signed-off-by:

The PLL configuration defined here sets 72MHz (which is correct), not 80MHz. Correct the comment. Reviewed-by:

The ov8865 sensor is sometimes found on x86 platforms enumerated via ACPI. Add an ACPI match table to the driver so that it's probed on those platforms. Signed-off-by:

ov8865_state_init() calls ov8865_state_mipi_configure() which uses __v4l2_ctrl_s_ctrl[_int64](). This means that sensor->mutex (which is also sensor->ctrls.handler.lock) must be locked before calling ov8865_state_init(). Note ov8865_state_mipi_configure() is also used in other places where the lock is already held so it cannot be changed itself. This fixes the following lockdep kernel WARN: [ 13.233421] WARNING: CPU: 0 PID: 8 at drivers/media/v4l2-core/v4l2-ctrls-api.c:833 __v4l2_ctrl_s_ctrl+0x4d/0x60 [videodev] ...

The kerneldoc for pm_runtime_set_suspended() says: "It is not valid to call this function for devices with runtime PM enabled" To satisfy that requirement, re-order the calls so that pm_runtime_enable() is the last one.

Add a link frequency to the cio2-bridge table of supported sensors. This means that the driver can parse supported link frequencies from firmware in the usual way and validate that it can accommodate them. Signed-off-by:

The OV5693 is a 5 Mpx CMOS image sensor, connected via MIPI CSI-2. The chip is capable of a single lane configuration, but currently only two lanes are supported. Most of the sensor's features are supported, with the main exception being the lens correction algorithm. The driver provides all mandatory, optional and recommended V4L2 controls for maximum compatibility with libcamera. [mchehab: fixed a coding style warning] Signed-off-by:

The .suspend() and .resume() runtime_pm operations for the ipu3-cio2 driver currently do not handle the sensor's stream. Setting .s_stream() on or off for the sensor subdev means that sensors will pause and resume the stream at the appropriate time even if their drivers don't implement those operations. Reviewed-by:

pm_runtime_resume_and_get should be called when the s_frame_interval is called. The driver will try to access device registers to configure VMAX, coarse time and exposure. Currently if the runtime is not resumed, this fails: # media-ctl -d /dev/media0 --set-v4l2 '"IMX274 1-001a":0[fmt:SRGGB10_1X10/3840x2 160@1/10]' IMX274 1-001a: imx274_binning_goodness: ask 3840x2160, size 3840x2160, goodness 0 IMX274 1-001a: imx274_binning_goodness: ask 3840x2160, size 1920x1080, goodness -3000 IMX274 1-001a: imx274_binning_goodness: ask 3840x2160, size 1280x720, goodness -4000 IMX274 1-001a: imx274_binning_goodness: ask 3840x2160, size 1280x540, goodness -4180 IMX274 1-001a: __imx274_change_compose: selected 1x1 binning IMX274 1-001a: imx274_set_frame_interval: input frame interval = 1 / 10 IMX274 1-001a: imx274_read_mbreg : addr 0x300e, val=0x1 (2 bytes) IMX274 1-001a: imx274_set_frame_interval : register SVR = 1 IMX274 1-001a: imx274_read_mbreg : addr 0x30f6, val=0x6a8 (2 bytes) IMX274 1-001a: imx274_set_frame_interval : register HMAX = 1704 IMX274 1-001a: imx274_set_frame_length : input length = 2112 IMX274 1-001a: imx274_write_mbreg : i2c bulk write failed, 30f8 = 884 (3 bytes) IMX274 1-001a: imx274_set_frame_length error = -121 IMX274 1-001a: imx274_set_frame_interval error = -121 Unable to setup formats: Remote I/O error (121) The device is not resumed thus the remote I/O error.

The MAX9286 has not explicitly declared a dependency upon VIDEO_V4L2. While this dependency has likely always been met by configurations including it, the device does use V4L2 core, and should depend upon it. Add VIDEO_V4L2 as a dependency to match other drivers and prevent failures when compile testing. Signed-off-by:

The commented code actually is an issue that require fixes, so, move the container_of() call to the commented code, and drop the unused function.
