This series improves crc-core <-> driver interface. This series adds following functionality in the crc-core - Now control node will print all the available sources if implemented by driver along with current source. - Setting of sorce will fail if provided source is not supported - cleanup of crtc_crc_open function first allocate memory before enabling CRC generation - Don't block open() call instead wait in crc read call.
Following IGT will fail due to crc-core <-> driver interface change igt@kms_pipe_crc_basic@bad-source <now setting bad-source itself will fail> ig@kms_pipe_crc_basic@nonblocking-crc-pipe-X ig@kms_pipe_crc_basic@nonblocking-crc-pipe-X-frame-sequence In nonblocking crc tests we'll get lesser crc's due to skipping crc
AMD/Rockchip/rcar code path is not validated and may need inputs
