  19
  20timer {
  21        compatible = "lsi,zevio-timer";
  22        reg = <0x900D0000 0x1000>, <0x900A0020 0x8>;
  23        interrupts = <19>;
  24        clocks = <&timer_clk>;
  25};

  27Example (no clock-events):
  28
  29timer {
  30        compatible = "lsi,zevio-timer";
  31        reg = <0x900D0000 0x1000>;
  32        clocks = <&timer_clk>;
