   3 Required properties:
   4  - compatible: "img,pistachio-gptimer".
   5  - reg: Address range of the timer registers.
   6  - interrupts: An interrupt for each of the four timers
   7  - clocks: Should contain a clock specifier for each entry in clock-names
   8  - clock-names: Should contain the following entries:
   9                 "sys", interface clock
  10                 "slow", slow counter clock
  11                 "fast", fast counter clock
  12  - img,cr-periph: Must contain a phandle to the peripheral control
  13                   syscon node.

  16         timer: timer@18102000 {
