Subject: [PATCH 5.10 12/16] xhci-pci: Allow host runtime PM as default for Intel Maple Ridge xHCI
Date: Sat, 19 Dec 2020 13:57:19 +0100 [thread overview]
Message-ID: <20201219125339.673011054@linuxfoundation.org> (raw)
In-Reply-To: <20201219125339.066340030@linuxfoundation.org>
From: Mika Westerberg <mika.westerberg@linux.intel.com>
commit 5a8e3229ac27956bdcc25b2709e5d196d109a27a upstream.
Intel Maple Ridge is successor of Titan Ridge Thunderbolt controller. As
Titan Ridge this one also includes xHCI host controller. In order to
safe energy we should put it to low power state by default when idle.
For this reason allow host runtime PM for Maple Ridge.
