[PATCHv4 1/3] ARM: dts: Add board dts file for Exynos3250-based Rinato board
From: Chanwoo Choi
Date: Fri Oct 24 2014 - 09:13:46 EST
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
