1	* Designware APB timer
2	
3	Required properties:
4	- compatible: One of:
5	 	"snps,dw-apb-timer"
6		"snps,dw-apb-timer-sp" <DEPRECATED>
7		"snps,dw-apb-timer-osc" <DEPRECATED>
8	- reg: physical base address of the controller and length of memory mapped
9	  region.
10	- interrupts: IRQ line for the timer.
11	- either clocks+clock-names or clock-frequency properties
12	
13	Optional properties:
14	- clocks	: list of clock specifiers, corresponding to entries in
15			  the clock-names property;
16	- clock-names	: should contain "timer" and "pclk" entries, matching entries
17			  in the clocks property.
18	- clock-frequency: The frequency in HZ of the timer.
19	- clock-freq: For backwards compatibility with picoxcell
20	
21	If using the clock specifiers, the pclk clock is optional, as not all
22	systems may use one.
23	
24	
25	Example:
26		timer@ffe00000 {
27			compatible = "snps,dw-apb-timer";
28			interrupts = <0 170 4>;
29			reg = <0xffe00000 0x1000>;
30			clocks = <&timer_clk>, <&timer_pclk>;
31			clock-names = "timer", "pclk";
32		};
