1* Device tree bindings for Texas Instruments DaVinci timer
2
3This document provides bindings for the 64-bit timer in the DaVinci
4architecture devices. The timer can be configured as a general-purpose 64-bit
5timer, dual general-purpose 32-bit timers. When configured as dual 32-bit
6timers, each half can operate in conjunction (chain mode) or independently
7(unchained mode) of each other.
8
9The timer is a free running up-counter and can generate interrupts when the
10counter reaches preset counter values.
11
12Also see ../watchdog/davinci-wdt.txt for timers that are configurable as
13watchdog timers.

15Required properties:
16
17- compatible : should be "ti,da830-timer".
18- reg : specifies base physical address and count of the registers.
19- interrupts : interrupts generated by the timer.
20- interrupt-names: should be "tint12", "tint34", "cmpint0", "cmpint1",
21		   "cmpint2", "cmpint3", "cmpint4", "cmpint5", "cmpint6",
22		   "cmpint7" ("cmpintX" may be omitted if not present in the
23		   hardware).
24- clocks : the clock feeding the timer clock.
25
26Example:
27
28	clocksource: timer@20000 {
29		compatible = "ti,da830-timer";
30		reg = <0x20000 0x1000>;
31		interrupts = <21>, <22>, <74>, <75>, <76>, <77>, <78>, <79>,
32			     <80>, <81>;
33		interrupt-names = "tint12", "tint34", "cmpint0", "cmpint1",
34				  "cmpint2", "cmpint3", "cmpint4", "cmpint5",
35				  "cmpint6", "cmpint7";
36		clocks = <&pll0_auxclk>;
37	};
