Subject: [PATCH] PCI/PM: Note that PME can be generated from D0
Date: Wed, 16 Oct 2019 14:44:50 -0500 [thread overview]
Message-ID: <20191016194450.68959-1-helgaas@kernel.org> (raw)
From: Bjorn Helgaas <bhelgaas@google.com>
Per PCIe r5.0 sec 7.5.2.1, PME may be generated from D0, so update
Documentation/power/pci.rst to reflect that.

presence of additional voltage (3.3Vaux) allowing the device to remain
sufficiently active to generate a wakeup signal.
