ARM: dts: Add board dts file for exynos3250-rinato
This patch adds support for device tree source for Samsung Rinato board (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 Signed-off-by: Chanwoo Choi <cw00.choi@samsung.com> Signed-off-by: Inki Dae <inki.dae@samsung.com> Signed-off-by: Seung-Woo Kim <sw0312.kim@samsung.com> Signed-off-by: Jaehoon Chung <jh80.chung@samsung.com> Signed-off-by: Kyungmin Park <kyungmin.park@samsung.com> Signed-off-by: Kukjin Kim <kgene.kim@samsung.com>
