   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.

  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         };
