1 OMAP Timer bindings
2
3 Required properties:
4 - compatible:           Should be set to one of the below. Please note that
5                         OMAP44xx devices have timer instances that are 100%
6                         register compatible with OMAP3xxx devices as well as
7                         newer timers that are not 100% register compatible.
8                         So for OMAP44xx devices timer instances may use
9                         different compatible strings.
10
11                         ti,omap2420-timer (applicable to OMAP24xx devices)
12                         ti,omap3430-timer (applicable to OMAP3xxx/44xx devices)
13                         ti,omap4430-timer (applicable to OMAP44xx devices)
14                         ti,omap5430-timer (applicable to OMAP543x devices)
15                         ti,am335x-timer (applicable to AM335x devices)
16                         ti,am335x-timer-1ms (applicable to AM335x devices)
17
18 - reg:                  Contains timer register address range (base address and
19                         length).
20 - interrupts:           Contains the interrupt information for the timer. The
21                         format is being dependent on which interrupt controller
22                         the OMAP device uses.
23 - ti,hwmods:            Name of the hwmod associated to the timer, "timer<X>",
24                         where <X> is the instance number of the timer from the
25                         HW spec.
26
27 Optional properties:
28 - ti,timer-alwon:       Indicates the timer is in an alway-on power domain.
29 - ti,timer-dsp:         Indicates the timer can interrupt the on-chip DSP in
30                         addition to the ARM CPU.
31 - ti,timer-pwm:         Indicates the timer can generate a PWM output.
32 - ti,timer-secure:      Indicates the timer is reserved on a secure OMAP device
33                         and therefore cannot be used by the kernel.

35 Example:
36
37 timer12: timer@48304000 {
38         compatible = "ti,omap3430-timer";
39         reg = <0x48304000 0x400>;
40         interrupts = <95>;
41         ti,hwmods = "timer12"
42         ti,timer-alwon;
43         ti,timer-secure;
44 };
