The uvcvideo driver historically uses the /* Comment * style */ for multi-line block comments, which is frowned upon. Patches for the driver are required to use the more standard /* * Comment * style */ style. This result in inconsistencies. Fix it by converting all remaining instances of the old style.

The CSIS CSI-2 receiver in the i.MX8MP seems to be identical to the version present in the i.MX8MM. Add a device-specific compatible string, with a fallback to the i.MX8MM compatible. Signed-off-by:

The CSIS is connected to its sink through an SoC-specific gasket that needs to be configured. Depending on the platform, the gasket configuration requires knowing the CSI-2 DT. To provide the needed information, implement the .get_frame_desc() operation. Signed-off-by:

Register at offset 0x00 isn't documented, but the NXP BSP imx8-mipi-csi2-sam driver defines it as a version register. Tests on i.MX7D and i.MX8MP have confirmed this, with values matching the version of the IP core specified in the respective reference manuals. This commit doesn't make use of the version register at runtime as the compatible strings are enough to identify the IP core version. Nonetheless, capturing the information in register definitions that don't affect the code negatively is useful for future development. Signed-off-by:

HEVC uAPI is used by 2 mainline drivers (Hantro, Cedrus) and at least 2 out-of-tree drivers (rkvdec, RPi). The uAPI has been reviewed so it is time to make it 'public' by un-staging it. Signed-off-by:

The number of 'entry point offset' can be very variable. Instead of using a large static array define a v4l2 dynamic array of U32 (V4L2_CTRL_TYPE_U32). The number of entry point offsets is reported by the elems field and in struct v4l2_ctrl_hevc_slice_params.num_entry_point_offsets field. Signed-off-by:

The HEVC specification describes the following: "PicOrderCntVal is derived as follows: PicOrderCntVal = PicOrderCntMsb + slice_pic_order_cnt_lsb The value of PicOrderCntVal shall be in the range of −2^31 to 2^31 − 1, inclusive." To match with these definitions change __u16 pic_order_cnt[2] into __s32 pic_order_cnt_val. Change v4l2_ctrl_hevc_slice_params->slice_pic_order_cnt to __s32 too. Signed-off-by:

Add a new flag that indicates that this control is a dynamically sized array. Also document this flag. Currently dynamically sized arrays are limited to one dimensional arrays, but that might change in the future if there is a need for it. The initial use-case of dynamic arrays are stateless codecs. A frame can be divided in many slices, so you want to provide an array containing slice information for each slice. Typically the number of slices is small, but the standard allow for hundreds or thousands of slices. Dynamic arrays are a good solution since sizing the array for the worst case would waste substantial amounts of memory. Acked-by:

stm32-dcmi calls its source subdev with v4l2_subdev_call() using a v4l2_subdev_state constructed on stack. This means that init_cfg is never called for that state, and a source subdev that depends on the init_cfg call may break. A new macro has been added for this particular purpose, which properly initializes the state, so let's use v4l2_subdev_call_state_try() here. Signed-off-by:

Add a helper macro for the situations where a non-MC driver needs to call a state-operation (operation which takes a subdev state as a parameter) in try-context in another subdev. The macro allocates a new subdev state for the called subdev and frees the state afterwards. An example use case is a media platform driver testing if a v4l2_subdev_format would be accepted by a source subdev. This should not be used in MC drivers. Signed-off-by:
