From 510d242f498a00f4701b77c6f42df880abacb3bd Mon Sep 17 00:00:00 2001 From: Evan Quan Date: Fri, 21 Jul 2023 19:18:00 +0800 Subject: [PATCH] drm/amd/pm: disable the SMU13 OD feature support temporarily The existing OD interface cannot support the growing demand for more OD features. We are in the transition to a new OD mechanism. So, disable the SMU13 OD feature support temporarily. And this should be reverted when the new OD mechanism online.
