Subject: [PATCH 3/4] ARM: dts: dra7: Add DT property to allow unaligned mem access to PCIe RC
Date: Fri, 1 Dec 2017 11:43:10 +0530 [thread overview]
Message-ID: <20171201061311.16691-4-vigneshr@ti.com> (raw)
In-Reply-To: <20171201061311.16691-1-vigneshr@ti.com>
Add ti,syscon-unaligned-access property to PCIe RC nodes in order to
enable workaround for errata i870 in PCIe RC mode as well.
