Subject: media: imx: capture: Expose V4L2_CAP_IO_MC for the MC-centric API
Author:  Laurent Pinchart <[email protected]>
Date:    Mon Feb 15 05:26:52 2021 +0100

Report to userspace that the MC-centric API is MC-centric by exposing
the V4L2_CAP_IO_MC. This requires adding support for mbus code filtering
in format enumeration, as required by V4L2_CAP_IO_MC.
