V4L2_FMTDESC_FLAG_ENUM_ALL flag goal is to enumerate all possible pixel format while ignoring the current configuration. The series add tests for v4l2-compliance and v4l2-ctl tools. v4l2-compliance will check is the flag is supported by drivers and verify if the enumerated list is an upperset of VIDIO_ENUM_FMT called without the flag. Add 'all' supoption to vidcap --list-formats(-ext) options to use V4L2_FMTDESC_FLAG_ENUM_ALL if supported by the driver. As example, Verisilicon driver support the flag usage and give these results: ./v4l2-ctl --list-formats -d 1 ioctl: VIDIOC_ENUM_FMT Type: Video Capture Multiplanar [0]: 'VT12' (Y/UV 4:2:0 (4x4 Linear)) [1]: 'NV12' (Y/UV 4:2:0) ./v4l2-ctl --list-formats all -d 1 ioctl: VIDIOC_ENUM_FMT Type: Video Capture Multiplanar [0]: 'VT12' (Y/UV 4:2:0 (4x4 Linear)) [1]: 'T010' (10-bit Y/UV 4:2:0 (4x4 Linear)) [2]: 'NV12' (Y/UV 4:2:0) [3]: 'P010' (10-bit Y/UV 4:2:0) so userspace can discover that it support 10-bit formats on capture queue.
