From 475c6285cf38480eb39cc62b48c4c95cacd2fc15 Mon Sep 17 00:00:00 2001 From: Chen-Yu Tsai Date: Fri, 31 Oct 2014 11:05:48 +0800 Subject: [PATCH] ARM: dts: sun9i: Enable i2c3 on A80 Optimus board i2c3 is exposed on the GPIO extension header. Enable it so we can use it. Also enable internal pull-ups on the pins, as they don't seem to have external pull-up resistors.
