Subject: [PATCH v3 5/6] MIPS: dts: mscc: Add i2c on ocelot
Date:   Mon,  6 Aug 2018 20:54:11 +0200
Message-Id: <20180806185412.7210-6-alexandre.belloni@bootlin.com>
In-Reply-To: <20180806185412.7210-1-alexandre.belloni@bootlin.com>
References: <20180806185412.7210-1-alexandre.belloni@bootlin.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Ocelot has an i2c controller, add it. There is only one possible pinmux
configuration so add it as well.
