* 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>; |
|
};
