From 7c00985109f95474a7fe31f03022126e23e355ff Mon Sep 17 00:00:00 2001 From: Tomi Valkeinen Date: Tue, 10 Nov 2015 17:59:50 -0600 Subject: [PATCH] drm/omap: add writeback funcs to dispc_ops Add writeback specific dispc functions to dispc_ops so that omapdrm can use them. Also move 'enum dss_writeback_channel' to the public omapdss.h for omapdrm.
