[PATCH v3 20/61] drm/omap: dss: Add functions to connect and disconnect devices
Laurent Pinchart
laurent.pinchart at ideasonboard.com
Mon Aug 6 00:27:00 UTC 2018
The omap_dss_device objects model display components and are connected
at runtime to create display pipelines. The connect and disconnect
operations implemented by each component contain lots of duplicate code.
As a first step towards fixing this, create new functions to wrap the
direct calls to those operations and use them.
