Subject: [PATCH 4/4] xhci-pci: Allow host runtime PM as default for AMD Pink Sardine
Date: Wed, 5 Oct 2022 15:23:52 -0500 [thread overview]
Message-ID: <20221005202353.1269-5-mario.limonciello@amd.com> (raw)
In-Reply-To: <20221005202353.1269-1-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.
Signed-off-by: Mario Limonciello <mario.limonciello@amd.com>
