1* OMAP PWM for dual-mode timers
2
3Required properties:
4- compatible: Shall contain "ti,omap-dmtimer-pwm".
5- ti,timers: phandle to PWM capable OMAP timer. See timer/ti,timer-dm.yaml for info
6  about these timers.
7- #pwm-cells: Should be 3. See pwm.yaml in this directory for a description of
8  the cells format.
9
10Optional properties:
11- ti,prescaler: Should be a value between 0 and 7, see the timers datasheet
12- ti,clock-source: Set dmtimer parent clock, values between 0 and 2:
13  - 0x00 - high-frequency system clock (timer_sys_ck)
14  - 0x01 - 32-kHz always-on clock (timer_32k_ck)
15  - 0x02 - external clock (timer_ext_ck, OMAP2 only)
16
17Example:
18	pwm9: dmtimer-pwm@9 {
19		compatible = "ti,omap-dmtimer-pwm";
20		ti,timers = <&timer9>;
21		#pwm-cells = <3>;
22	};
