Hi Mahesh,

Thank you for the patches.

When resubmitting patch series, could you please add a version number to the
[PATCH] prefix ? Otherwise it gets difficult to figure out which version is
the latest. This can be done automatically with the -v argument to git-format-
patch.
sure :), added patch prefix (now v4) and re-floated the series after addressing review comments in patches 03/10, 08/10 & 10/10.

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 need inputs
