From c4ff6ea60eb13953df58d786ffadce47e0c90ceb Mon Sep 17 00:00:00 2001 From: Laurent Pinchart Date: Sat, 5 Aug 2017 01:44:16 +0300 Subject: [PATCH] drm: omapdrm: Move PCD, LINEWIDTH and DOWNSCALE features to dispc driver The FEAT_PARAM_DSS_PCD, FEAT_PARAM_LINEWIDTH and FEAT_PARAM_DOWNSCALE features are specific to the DISPC, move them from the omap_dss_features structure to the dispc driver.
