acpi_device_id are not supposed to change at runtime. All functions working with acpi_device_id provided by <acpi/acpi_bus.h> work with const acpi_device_id. So mark the non-const structs as const.

The rectangle which the sink compose rectangle is related to is documented to be the source compose bounds rectangle. This is in obvious conflict with the ground rule of the format propagation (from sink to source). The reason behind this is that this was always supposed to be the sink compose bounds rectangle. Fix it. Fixes: 955f645a ("[media] v4l: Add subdev selections documentation") Signed-off-by:

Add suport for standard integer menu V4L2_CID_LINK_FREQ control. The CSI2 link frequency value is specific for each sensor mode so the sensor mode structure is extended to add this. The control is made read-only and its value is updated when the sensor mode is changed - on set_format. Signed-off-by:

If endpoint has an invalid configuration, ignore it instead of happily proceeding to use it nonetheless. Ignoring such an endpoint is better than failing since there could be multiple endpoints, only some of which are bad. Signed-off-by:

In the vast majority of cases the bus type is known to the driver(s) since a receiver or transmitter can only support a single one. There are cases however where different options are possible, or the bus type cannot be automatically detected. The existing V4L2 OF support tries to figure out the bus type and parse the bus parameters based on that. This does not scale too well as there are multiple serial busses that share common properties. Some hardware also supports multiple types of busses on the same interfaces. Signed-off-by:

This fixes visual artifacts in the first macroblock row of encoded MPEG-4 video output caused by 8 additional lines of luma data leaking into the chroma planes of the internal reference framebuffers: the buffer size is rounded up to a multiple of 16x16 macroblock size, same as for the h.264 encoder.

CodaDx6 only accepts GOP sizes up to 60 frames, but CODA960 can handle up to 99 frames. If we disable automatic I frame generation altogether by setting GOP size to 0, we can let an application produce arbitrarily large I frame intervals using the V4L2_CID_MPEG_VIDEO_FORCE_KEY_FRAME control.
