* OMAP PWM for dual-mode timers
|
||
|
|
|
||
|
|
Required properties:
|
||
|
|
- compatible: Shall contain "ti,omap-dmtimer-pwm".
|
||
|
|
- ti,timers: phandle to PWM capable OMAP timer. See timer/ti,timer.txt for info
|
||
|
|
about these timers.
|
||
|
|
- #pwm-cells: Should be 3. See pwm.yaml in this directory for a description of
|
||
|
|
the cells format.
|
||
|
|
|
||
|
|
Optional properties:
|
||
|
|
- ti,prescaler: Should be a value between 0 and 7, see the timers datasheet
|
||
|
|
- ti,clock-source: Set dmtimer parent clock, values between 0 and 2:
|
||
|
|
- 0x00 - high-frequency system clock (timer_sys_ck)
|
||
|
|
- 0x01 - 32-kHz always-on clock (timer_32k_ck)
|
||
|
|
- 0x02 - external clock (timer_ext_ck, OMAP2 only)
|
||
|
|
|
||
|
|
Example:
|
||
|
|
pwm9: dmtimer-pwm@9 {
|
||
|
|
compatible = "ti,omap-dmtimer-pwm";
|
||
|
|
ti,timers = <&timer9>;
|
||
|
|
#pwm-cells = <3>;
|
||
|
|
};
