From 7b7aa62c05eac9789c208b946f515983a9255d8d Mon Sep 17 00:00:00 2001 From: Marek Szyprowski Date: Thu, 7 Jun 2018 13:07:49 +0200 Subject: [PATCH] drm/exynos: decon5433: Fix WINCONx reset value The only bits that should be preserved in decon_win_set_fmt() is WINCONx_ENWIN_F. All other bits depends on the selected pixel formats and are set by the mentioned function.
