* Device tree bindings for Texas instruments Keystone timer
|
|
This document provides bindings for the 64-bit timer in the KeyStone
|
architecture devices. The timer can be configured as a general-purpose 64-bit
|
timer, dual general-purpose 32-bit timers. When configured as dual 32-bit
|
timers, each half can operate in conjunction (chain mode) or independently
|
(unchained mode) of each other.

Required properties:
|
|
- compatible : should be "ti,keystone-timer".
|
- reg : specifies base physical address and count of the registers.
|
- interrupts : interrupt generated by the timer.
|
- clocks : the clock feeding the timer clock.
|
|
Example:
|
|
timer@22f0000 {
|
compatible = "ti,keystone-timer";
|
reg = <0x022f0000 0x80>;
|
interrupts = <GIC_SPI 110 IRQ_TYPE_EDGE_RISING>;
|
clocks = <&clktimer15>;
|
};
