1OMAP Timer bindings
2
3Required properties:
4- compatible: Must be "ti,omap2-timer" for OMAP2+ controllers.
5- reg: Contains timer register address range (base address and
6 length).
7- interrupts: Contains the interrupt information for the timer. The
8 format is being dependent on which interrupt controller
9 the OMAP device uses.
10- ti,hwmods: Name of the hwmod associated to the timer, "timer<X>",
11 where <X> is the instance number of the timer from the
12 HW spec.
13
14Optional properties:
15- ti,timer-alwon: Indicates the timer is in an alway-on power domain.
16- ti,timer-dsp: Indicates the timer can interrupt the on-chip DSP in
17 addition to the ARM CPU.
18- ti,timer-pwm: Indicates the timer can generate a PWM output.
19- ti,timer-secure: Indicates the timer is reserved on a secure OMAP device
20 and therefore cannot be used by the kernel.
21
