| * Device tree bindings for Texas Instruments DaVinci timer |
| |
| This document provides bindings for the 64-bit timer in the DaVinci |
| architecture devices. The timer can be configured as a general-purpose 64-bit |
| timer, dual general-purpose 32-bit timers. When configured as dual 32-bit |
| timers, each half can operate in conjunction (chain mode) or independently |
| (unchained mode) of each other. |
| |
| The timer is a free running up-counter and can generate interrupts when the |
| counter reaches preset counter values. |
| |
| Also see ../watchdog/davinci-wdt.txt for timers that are configurable as |
| watchdog timers. |
| |
| Required properties: |
| |
| - compatible : should be "ti,da830-timer". |
| - reg : specifies base physical address and count of the registers. |
| - interrupts : interrupts generated by the timer. |
| - interrupt-names: should be "tint12", "tint34", "cmpint0", "cmpint1", |
| "cmpint2", "cmpint3", "cmpint4", "cmpint5", "cmpint6", |
| "cmpint7" ("cmpintX" may be omitted if not present in the |
| hardware). |
| - clocks : the clock feeding the timer clock. |
| |
| Example: |
| |
| clocksource: timer@20000 { |
| compatible = "ti,da830-timer"; |
| reg = <0x20000 0x1000>; |
| interrupts = <21>, <22>, <74>, <75>, <76>, <77>, <78>, <79>, |
| <80>, <81>; |
| interrupt-names = "tint12", "tint34", "cmpint0", "cmpint1", |
| "cmpint2", "cmpint3", "cmpint4", "cmpint5", |
| "cmpint6", "cmpint7"; |
| clocks = <&pll0_auxclk>; |
| }; |
