Subject: [PATCH 1/2] drm/amd/pm: not stop rlc for IMU enabled APUs when suspend
Date: Mon, 30 Oct 2023 16:36:57 +0800	[thread overview]
Message-ID: <20231030083658.537469-1-Tim.Huang@amd.com> (raw)

For IMU enabled APUs, after sending the PrepareMp1ForUnload message
to SMU in system_features_control, the RLC registers can't be touched.
The driver to stop the rlc in suspending is no longer required.
