Required properties:
 
4
- compatible : "snps,dw-apb-uart"
 
5
- reg : offset and length of the register set for the device.
 
6
- interrupts : should contain uart interrupt.
 
7
- clock-frequency : the input clock frequency for the UART.

9
Optional properties:
 
10
- reg-shift : quantity to shift the register offsets by.  If this property is
 
11
  not present then the register offsets are not shifted.
 
12
- reg-io-width : the size (in bytes) of the IO accesses that should be
 
13
  performed on the device.  If this property is not present then single byte
 
14
  accesses are used.

                clock-frequency = <3686400>;
 
22
                interrupts = <10>;
