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. 14 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 };
