Subject: [PATCH 1/2] ARM: dts: Add TOPEET itop core board SCP package version
The TOPEET itop is a samsung exnynos 4412 core board, which have
two package versions. This patch add the support for SCP version.
Currently supported are USB3503A HSIC, USB OTG, eMMC and PMIC.
The future features are in the based board. Also MFC and watchdog
have been enabled. The RTC clock source comes from PMIC, addtional
clk driver is needed.
