[PATCH 00/10] Improve crc-core driver interface

[Mahesh Kumar <mahesh1.kumar@intel.com>]

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
