-* 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-dm.yaml 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 at 9 {
- compatible = "ti,omap-dmtimer-pwm";
- ti,timers = <&timer9>;
- #pwm-cells = <3>;
- };
