- ARM Global Timer
Cortex-A9 are often associated with a per-core Global timer.
** Timer node required properties:
compatible : should contain
* "arm,cortex-a5-global-timer" for Cortex-A5 global timers. * "arm,cortex-a9-global-timer" for Cortex-A9 global timers or any compatible implementation. Note: driver supports versions r2p0 and above.
interrupts : One interrupt to each core
reg : Specify the base address and the size of the GT timer
register window.clocks : Should be phandle to a clock.
Example:
timer@2c000600 {
compatible = "arm,cortex-a9-global-timer";
reg = <0x2c000600 0x20>;
interrupts = <1 13 0xf01>;
clocks = <&arm_periph_clk>;
};
