  1. * ARM Global Timer
  2. Cortex-A9 are often associated with a per-core Global timer.
  3. ** Timer node required properties:
  4. - compatible : Should be "arm,cortex-a9-global-timer"
  5. Driver supports versions r2p0 and above.
  6. - interrupts : One interrupt to each core
  7. - reg : Specify the base address and the size of the GT timer
  8. register window.
  9. - clocks : Should be phandle to a clock.
  10. Example:
  11. timer@2c000600 {
  12. compatible = "arm,cortex-a9-global-timer";
  13. reg = <0x2c000600 0x20>;
  14. interrupts = <1 13 0xf01>;
  15. clocks = <&arm_periph_clk>;
  16. };
