From a676a97623d399f7a2174b347d688412864d385a Mon Sep 17 00:00:00 2001 From: Huang Rui Date: Mon, 27 Jul 2020 16:19:45 +0800 Subject: [PATCH] drm/amdgpu: skip crit temperature values on APU (v2) It doesn't expose PPTable descriptor on APU platform. So max/min temperature values cannot be got from APU platform. v2: Stoney needs to skip crit temperature as well.
