Subject: [PATCH v4 6/7] MIPS: dts: mscc: Add i2c on ocelot
Date: Thu, 16 Aug 2018 10:45:20 +0200 [thread overview]
Message-ID: <20180816084521.16289-7-alexandre.belloni@bootlin.com> (raw)
In-Reply-To: <20180816084521.16289-1-alexandre.belloni@bootlin.com>
Ocelot has an i2c controller, add it. There is only one possible pinmux
configuration so add it as well.
