* 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.
