0001 * Device tree bindings for Texas instruments Keystone timer
0002
0003 This document provides bindings for the 64-bit timer in the KeyStone
0004 architecture devices. The timer can be configured as a general-purpose 64-bit
0005 timer, dual general-purpose 32-bit timers. When configured as dual 32-bit
0006 timers, each half can operate in conjunction (chain mode) or independently
0007 (unchained mode) of each other.

0009 It is global timer is a free running up-counter and can generate interrupt
0010 when the counter reaches preset counter values.

0015 Required properties:
0016
0017 - compatible : should be "ti,keystone-timer".
0018 - reg : specifies base physical address and count of the registers.
0019 - interrupts : interrupt generated by the timer.
0020 - clocks : the clock feeding the timer clock.

0022 Example:
0023
0024 timer@22f0000 {
0025 compatible = "ti,keystone-timer";
0026 reg = <0x022f0000 0x80>;
0027 interrupts = <GIC_SPI 110 IRQ_TYPE_EDGE_RISING>;
0028 clocks = <&clktimer15>;
0029 };
