This patch add support for device tree sources for Samsung Rinato baord
(Gear 2) based on Exynos3250 SoC.

This dts file support following features:
- eMMC
- Main PMIC (Samsung S2MPS14)
- Interface PMIC (Maxim MAX77836, MUIC, fuel-gauge, charger)
- RTC of Exynos3250
- ADC of Exynos3250 with NTC thermistor
- I2S of Exynos3250
- TMU of Exynos3250
- MFC of Exynos3250
- Secure firmware for Exynos3250 secondary cpu boot
- Serial ports of Exynos3250
- gpio-key for power key

Hi Chanwoo,

I wonder if this regulator-fixed is needed. The LDO11 and LDO12 has
external GPIO control set up. So maybe this could be removed?

Best regards,
Krzysztof

OK, I'll remove 'vemmc_reg' and then use ldo12_reg insead of 'vemmc_reg' on mshc_0 dt node.
