From 1ac0c894032692d3cb25583e33ceaea78cc8ab4b Mon Sep 17 00:00:00 2001 From: Laurent Pinchart Date: Sat, 5 Aug 2017 01:44:14 +0300 Subject: [PATCH] drm: omapdrm: Move FEAT_* features to dispc driver All the remaining FEAT_* features are specific to the DISPC, move them from the omap_dss_features structure to the dispc driver.
