* Samsung's UART Controller
The Samsung's UART controller is used for interfacing SoC with serial communicaion
devices.
Required properties:
- compatible: should be
- "samsung,exynos4210-uart", for UART's compatible with Exynos4210 uart ports.
- reg: base physical address of the controller and length of memory mapped
region.
- interrupts: interrupt number to the cpu. The interrupt specifier format depends
on the interrupt controller parent.
