Subject: drm/amd: Disable ASPM for VI w/ all Intel systems
From: Mario Limonciello <mario.limonciello@xxxxxxx>
commit 64ffd2f1d00c6235dabe9704bbb0d9ce3e28147f upstream.
Originally we were quirking ASPM disabled specifically for VI when
used with Alder Lake, but it appears to have problems with Rocket
Lake as well.
Like we've done in the case of dpm for newer platforms, disable
ASPM for all Intel systems.
