-From 757050ee4e2166ab406163e584e61a85417231a0 Mon Sep 17 00:00:00 2001
-From: Alex Deucher <alexander.deucher@amd.com>
-Date: Fri, 12 Feb 2016 00:39:13 -0500
-Subject: [PATCH 0310/1110] drm/amdgpu/gfx: clean up harvest configuration (v2)
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-Read back harvest configuration from registers and simplify
-calculations. No need to program the raster config registers.
-These are programmed as golden registers and the user mode
-drivers program them as well.
-
-v2: rebase on Tom's patches
-
-Reviewed-by: Christian König <christian.koenig@amd.com>
