From d43f81cbaf43531a977e8b4c4427f19acf8a5061 Mon Sep 17 00:00:00 2001 From: Terje Bergstrom Date: Fri, 22 Mar 2013 16:34:09 +0200 Subject: drm/tegra: Add gr2d device Add client driver for 2D device, and IOCTLs to pass work to host1x channel for 2D. Also adds functions that can be called to access sync points from DRM.
