1 * Device tree bindings for Texas Instruments DaVinci timer
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.
9 The timer is a free running up-counter and can generate interrupts when the
10 counter reaches preset counter values.
12 Also see ../watchdog/davinci-wdt.txt for timers that are configurable as
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
24 - clocks : the clock feeding the timer clock.
