Subject: [PATCH 5/8] ARM: dts: artpec: add and utilize artpec6 pin controller
Date:   Tue, 20 Feb 2018 18:00:46 +0100
Message-Id: <20180220170049.22809-6-niklas.cassel@axis.com>
In-Reply-To: <20180220170049.22809-1-niklas.cassel@axis.com>
References: <20180220170049.22809-1-niklas.cassel@axis.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Add node for the pin controller used in the artpec6 SoC,
and start using it for the exising UARTs.
