[PATCH] ARM: S5PC210: GPIO I2C devices support on universal board

Kyungmin Park kmpark at infradead.org

From: Kyungmin Park <kyungmin.park at samsung.com>

Universal board has several GPIO i2c devices.

Note that this patch depends on previous patch "ARM: S5PC210: Define more GPIOs to use the MP pins".
