| OMAP Timer bindings |
| |
| Required properties: |
| - compatible: Should be set to one of the below. Please note that |
| OMAP44xx devices have timer instances that are 100% |
| register compatible with OMAP3xxx devices as well as |
| newer timers that are not 100% register compatible. |
| So for OMAP44xx devices timer instances may use |
| different compatible strings. |
| |
| ti,omap2420-timer (applicable to OMAP24xx devices) |
| ti,omap3430-timer (applicable to OMAP3xxx/44xx devices) |
| ti,omap4430-timer (applicable to OMAP44xx devices) |
| ti,omap5430-timer (applicable to OMAP543x devices) |
| ti,am335x-timer (applicable to AM335x devices) |
| ti,am335x-timer-1ms (applicable to AM335x devices) |
| |
| - reg: Contains timer register address range (base address and |
| length). |
| - interrupts: Contains the interrupt information for the timer. The |
| format is being dependent on which interrupt controller |
| the OMAP device uses. |
| - ti,hwmods: Name of the hwmod associated to the timer, "timer<X>", |
| where <X> is the instance number of the timer from the |
| HW spec. |
| |
| Optional properties: |
| - ti,timer-alwon: Indicates the timer is in an alway-on power domain. |
| - ti,timer-dsp: Indicates the timer can interrupt the on-chip DSP in |
| addition to the ARM CPU. |
| - ti,timer-pwm: Indicates the timer can generate a PWM output. |
| - ti,timer-secure: Indicates the timer is reserved on a secure OMAP device |
| and therefore cannot be used by the kernel. |
| |
| Example: |
| |
| timer12: timer@48304000 { |
| compatible = "ti,omap3430-timer"; |
| reg = <0x48304000 0x400>; |
| interrupts = <95>; |
| ti,hwmods = "timer12" |
| ti,timer-alwon; |
| ti,timer-secure; |
| }; |
