From 8473c1387f6f23cd3d8174f5b87def48a3297bd4 Mon Sep 17 00:00:00 2001 From: Hawking Zhang <Hawking.Zhang@amd.com> Date: Fri, 23 Oct 2020 21:48:19 +0800 Subject: [PATCH 224/376] drm/amdgpu: disable rom clock gating support for APUs ROM clock gating enable/disable is not supported on APU platform. (i.e. CGTT_ROM_CLK_CTRL0 register is not availabe on APU). SMUIO callbacks will check APU flag before enable/disable rom clock gating, and skip the programming. Accordingly, query clock gating status through CGTT_ROM_CLK_CTRL0 also doesn't support on APU platform. The change applies to RAVEN/RAVEN2/PICASSO/RENOIR.
