Subject: [RFC PATCH 35/40] ARM: dts: keystone-k2e: Use the updated binding to describe PCIe in k2e
Date:   Fri, 21 Sep 2018 15:51:50 +0530
Message-ID: <20180921102155.22839-36-kishon@ti.com>
In-Reply-To: <20180921102155.22839-1-kishon@ti.com>

MIME-Version: 1.0
Content-Type: text/plain
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Use the updated binding to describe PCIe in k2e. (The older binding has
never worked in upstream kernel since serdes driver was never upstreamed).
