[PATCH v2 23/28] drm: omapdrm: Merge the dss_features and omap_dss_features structures
Laurent Pinchart
laurent.pinchart at ideasonboard.com
Mon May 8 11:32:58 UTC 2017
Both structures describe features of a particular OMAP DSS version,
there's no reason to keep them separate. Merge them together, allowing
initialization of the features based on the DSS compatible string
instead of the OMAP SoC version.
