From fecea2528d4e92db46eb11b23458ed56023301f2 Mon Sep 17 00:00:00 2001 From: Laurent Pinchart Date: Sat, 5 Aug 2017 01:43:52 +0300 Subject: [PATCH] drm: omapdrm: dss: Split operations out of dss_features structure Move the two function pointers to a new dss_ops structure. This will allow merging the dss_features and omap_dss_features structures without having to expose the DPI source selection and LCD clock muxing functions in header files.
