stable inclusion from stable-v5.10.127 commit 114080d04ae489e24509a0a348c283fb5ea3c5db category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I5XDDK
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=...
--------------------------------
commit 7516da47a349e74de623243a27f9b8a91446bf4f upstream.
In the same way as Intel Alder Lake TCSS (Type-C Subsystem) the Raptor Lake TCSS xHCI needs to be runtime suspended whenever possible to allow the TCSS hardware block to enter D3cold and thus save energy.
