Some devices do not implement all their controls in a way that complies with the UVC specification. This is for instance the case for several devices that do not support the disabled mode for the power line frequency control. Add a mechanism to allow per-device control mapping overrides to avoid errors when accessing non-compliant controls. Signed-off-by:

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.

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:

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:
