1	* Synopsys DesignWare ABP UART
2	
3	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.
8	
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.
15	
16	Example:
17	
18		uart@80230000 {
19			compatible = "snps,dw-apb-uart";
20			reg = <0x80230000 0x100>;
21			clock-frequency = <3686400>;
22			interrupts = <10>;
23			reg-shift = <2>;
24			reg-io-width = <4>;
