Subject: [PATCH 3/4] xhci-pci: Allow host runtime PM as default for Intel Raptor Lake xHCI
Date: Thu, 23 Jun 2022 14:19:44 +0300 [thread overview]
Message-ID: <20220623111945.1557702-4-mathias.nyman@linux.intel.com> (raw)
In-Reply-To: <20220623111945.1557702-1-mathias.nyman@linux.intel.com>
From: Tanveer Alam <tanveer1.alam@intel.com>
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.
