Subject: [PATCH] xhci-pci: Enable runtime PM on Alder Lake-N PCH xHCI controller
Date: Tue, 12 Jul 2022 20:24:42 +0800 [thread overview]
Message-ID: <20220712122442.22504-1-ben.kao@intel.com> (raw)
There are two Alder Lake-N xHCI host controllers with PCI IDs
0x464e and 0x54ed, now we add the quirk to default enable runtime
PM for 0x54ed.
