   1* Designware APB timer
   2
   3Required properties:
   4- compatible: "snps,dw-apb-timer-sp" or "snps,dw-apb-timer-osc"
   5- reg: physical base address of the controller and length of memory mapped
   6  region.
   7- interrupts: IRQ line for the timer.
   8- clock-frequency: The frequency in HZ of the timer.
   9- clock-freq: For backwards compatibility with picoxcell

  13                timer1: timer@ffc09000 {
  14                                compatible = "snps,dw-apb-timer-sp";
  15                                interrupts = <0 168 4>;
  16                                clock-frequency = <200000000>;
  17                                reg = <0xffc09000 0x1000>;
