Subject: [PATCH v2 2/5] PCI: Add quirk for PLDA's XpressRICH3 host bridge class.
Date: Fri,  9 Oct 2015 17:57:26 +0100	[thread overview]
Message-ID: <1444409849-5685-3-git-send-email-Liviu.Dudau@arm.com> (raw)
In-Reply-To: <1444409849-5685-1-git-send-email-Liviu.Dudau@arm.com>

The XpressRICH3 host bridge at power up has an unassigned class on
some of ARM Ltd boards, add a quirk to correct that.
