[igt-dev] [PATCH i-g-t v3 2/3] tests/kms_pipe_crc_basic: add nv12 crc sanity check

[Swati Sharma <swati2.sharma@intel.com>]

New CRC sanitycheck test case is added with NV12 format.
kms_plane@pixel-format test is validating all formats.
To improve BAT coverage we can have one planar format crc
sanity test.

v2: -improved documentation (Bhanu)
v3: -added check to skip format if not supported (CI)
