From e30c50cd79f088f33098b76ed01a33c724eafee3 Mon Sep 17 00:00:00 2001 From: Emily Deng Date: Wed, 12 Dec 2018 18:08:24 +0800 Subject: [PATCH] drm/amdgpu/psp_v3_1: Get psp fw version through reading register If PSP FW is running already, driver will not load PSP FW again and skip it. So psp fw version is not correct if reading it from FW binary file, need to get right version from register.
