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

| 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>; |
| }; |
