From 363b06aaa59fc20d0a9c5a5a9ce1fa2c45946700 Mon Sep 17 00:00:00 2001 From: Ville Syrjälä Date: Mon, 14 May 2012 11:08:51 +0900 Subject: drm/exynos: Use DRM_FORMAT_{NV12, YUV420} instead of DRM_FORMAT_{NV12M, YUV420M} MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The NV12M/YUV420M formats are identical to the already existing standard NV12/YUV420 formats. The M variants will be removed, so convert the driver to use the standard names.
