* Device tree bindings for Texas Instruments DaVinci timer



This document provides bindings for the 64-bit timer in the DaVinci

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.



The timer is a free running up-counter and can generate interrupts when the

counter reaches preset counter values.



Also see ../watchdog/davinci-wdt.txt for timers that are configurable as

watchdog timers.



Required properties:



- compatible : should be "ti,da830-timer".

- reg : specifies base physical address and count of the registers.

- interrupts : interrupts generated by the timer.

- interrupt-names: should be "tint12", "tint34", "cmpint0", "cmpint1",

		   "cmpint2", "cmpint3", "cmpint4", "cmpint5", "cmpint6",

		   "cmpint7" ("cmpintX" may be omitted if not present in the

		   hardware).

- clocks : the clock feeding the timer clock.



Example:



	clocksource: timer@20000 {

		compatible = "ti,da830-timer";

		reg = <0x20000 0x1000>;

		interrupts = <21>, <22>, <74>, <75>, <76>, <77>, <78>, <79>,

			     <80>, <81>;

		interrupt-names = "tint12", "tint34", "cmpint0", "cmpint1",

				  "cmpint2", "cmpint3", "cmpint4", "cmpint5",

				  "cmpint6", "cmpint7";

		clocks = <&pll0_auxclk>;

	};
