From 68b626c695df4dd054a40b1b9ffa71b55c912279 Mon Sep 17 00:00:00 2001

Subject: [PATCH 0574/1302] ARM: dts: Add missing aliases for I2C bus
controllers in exynos4412-m0.dts
When an I2C bus controller is added without a corresponding entry in
the aliases node the I2C core uses firs available number as the bus ID
which may be one of already reserved IDs for other controllers. E.g.
0...7 are reserved for hardware I2C bus controllers I2C0.I2C7.
Missing aliases were causing I2C0 bus adapter initialization to fail
due to bus ID 0 being assigned to one of the i2c-gpio controllers.
Fix this regression by adding corresponding node aliases.
