[PATCH 4/4] xhci-pci: Allow host runtime PM as default for AMD Pink Sardine

From: Mario Limonciello
Date: Wed Oct 05 2022 - 16:24:10 EST


The XHCI controllers not connected to the USB4 controller via a device
link can support D3. For optimal runtime power consumption on AMD Pink
Sardine, all XHCI controllers must support runtime suspend.
