This is to avoid pending interrupts to be handled during stream off, in which case, the ready buffer will be removed from buffer list, thus not all buffers can be returned to VB2 as expected. Disable CIO2 irq at cio2_hw_exit() so no new interrupts are generated. Signed-off-by:

Commit 828ee8c7 ("media: uvcvideo: Use ktime_t for timestamps") changed to use ktime_t for timestamps. Older Kernels use a struct for ktime_t, which requires the conversion function ktime_to_ns to be used on some places. With this patch it will compile now also for older Kernel versions.

While the sizeof is an operator and not a function, the preferred coding style in the kernel is to enclose its operand in parentheses. To avoid mixing multiple coding styles in the driver, use parentheses around all sizeof operands. While at it replace a kmalloc() with a kmalloc_array() to silence a checkpatch warning triggered by this patch. Signed-off-by:

The Microsoft HoloLens Sensors device has two separate frame descriptors with the same dimensions, each with a single different frame interval: VideoStreaming Interface Descriptor: bLength 30 bDescriptorType 36 bDescriptorSubtype 5 (FRAME_UNCOMPRESSED) bFrameIndex 1 bmCapabilities 0x00 Still image unsupported wWidth 1280 wHeight 481 dwMinBitRate 147763200 dwMaxBitRate 147763200 dwMaxVideoFrameBufferSize 615680 dwDefaultFrameInterval 333333 bFrameIntervalType 1 dwFrameInterval( 0) 333333 VideoStreaming Interface Descriptor: bLength 30 bDescriptorType 36 bDescriptorSubtype 5 (FRAME_UNCOMPRESSED) bFrameIndex 2 bmCapabilities 0x00 Still image unsupported wWidth 1280 wHeight 481 dwMinBitRate 443289600 dwMaxBitRate 443289600 dwMaxVideoFrameBufferSize 615680 dwDefaultFrameInterval 111111 bFrameIntervalType 1 dwFrameInterval( 0) 111111 Skip duplicate dimensions in enum_framesizes, let enum_frameintervals list the intervals from both frame descriptors. Change set_streamparm to switch to the correct frame index when changing the interval. This enables 90 fps capture on a Lenovo Explorer Windows Mixed Reality headset.

Use flags the device exposes for UVC controls. This allows the device to define which property flags are set. Since some cameras offer auto-adjustments for properties (e.g. auto-gain), the values of other properties (e.g. gain) can change in the camera. Examining the flags ensures that the driver is aware of such properties. Signed-off-by:

These sensor drivers have use case specific mode lists. This is currently not used nor there is a standard API for selecting the mode list. Disable configurations for non-preview modes until configuration selection is improved so that all the configurations are always usable. Signed-off-by:

Remove sensor driver's interface for setting the use case specific mode list as well as the mode lists that are related to other than CI_MODE_PREVIEW. This removes s_parm abuse in using driver specific values in v4l2_streamparm.capture.capturemode. The drivers already support [gs]_frame_interval so removing support for [gs]_parm is enough.

I usually update my config with make oldconfig and pressing return, trusting that whoever updates Kconfig sets sensible defaults. But my recent kernels ended up with all kinds of IR decoders built in that are not used by anything because they are all marked with default y. default y should only be set for something that prevents booting on common systems, never for some random weirdo driver feature like this. Remove all the "default y" in drivers/media/rc/Kconfig Signed-off-by:
