From: Jernej Skrabec Date: Fri, 1 Dec 2017 07:05:40 +0100 Subject: drm/sun4i: Add support for all HW supported DE2 RGB formats Git-commit: fba4955e9c4f2312314a902341c169f4bcbff735 Patch-mainline: v4.16-rc1 References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166 Currently only a few RGB formats are supported by the DE2 driver. Add support for all formats supported by the HW.
