    1 * Device tree bindings for Texas Instruments DaVinci timer
    2 
    3 This document provides bindings for the 64-bit timer in the DaVinci
    4 architecture devices. The timer can be configured as a general-purpose 64-bit
    5 timer, dual general-purpose 32-bit timers. When configured as dual 32-bit
    6 timers, each half can operate in conjunction (chain mode) or independently
    7 (unchained mode) of each other.
    8 
    9 The timer is a free running up-counter and can generate interrupts when the
   10 counter reaches preset counter values.
   11 
   12 Also see ../watchdog/davinci-wdt.txt for timers that are configurable as
   13 watchdog timers.
   14 
   15 Required 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 
   26 Example:
   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         };
