Subject: [RFC 3/3] xhci-pci: Allow host runtime PM as default for AMD Pink Sardine
Date: Mon, 3 Oct 2022 23:12:25 -0500 [thread overview]
Message-ID: <20221004041225.1462336-4-mario.limonciello@amd.com> (raw)
In-Reply-To: <20221004041225.1462336-1-mario.limonciello@amd.com>
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.
