Broadcom Kona Family timer
-----------------------------------------------------
This timer is used in the following Broadcom SoCs:
BCM11130, BCM11140, BCM11351, BCM28145, BCM28155
Required properties:
- compatible : "brcm,kona-timer"
- DEPRECATED: compatible : "bcm,kona-timer"
- reg : Register range for the timer
- interrupts : interrupt for the timer
- clocks: phandle + clock specifier pair of the external clock
- clock-frequency: frequency that the clock operates
Only one of clocks or clock-frequency should be specified.
Refer to clocks/clock-bindings.txt for generic clock consumer properties.
Example:
timer@35006000 {
compatible = "brcm,kona-timer";
reg = <0x35006000 0x1000>;
interrupts = <0x0 7 0x4>;
clocks = <&hub_timer_clk>;
};
