Exynos4412-trats2 board have light/proximity sensor. This patch add cm36651 light/ proximity sensor node for exynos4412. cm36651 is required properties as below. - Use i2c-gpio for cm36651 sensor. - Use fixed regulator for the IR LED. It is a part of the cm36651 for proximity detection. - cm36651 is i2c device driver so need to use i2c-gpio driver.
