From 494d63cf945925d2d311fcf5585ba136ef83860e Mon Sep 17 00:00:00 2001 From: Alex Deucher Date: Tue, 12 Dec 2017 15:20:22 -0500 Subject: [PATCH 2955/4131] drm/amdgpu: drop scratch regs save and restore from S3/S4 handling MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The expectation is that the base driver doesn't mess with these. Some components interact with these directly so let the components handle these directly.
