1 * OMAP PWM for dual-mode timers
2
3 Required properties:
4 - compatible: Shall contain "ti,omap-dmtimer-pwm".
5 - ti,timers: phandle to PWM capable OMAP timer. See arm/omap/timer.txt for info
6   about these timers.
7 - #pwm-cells: Should be 3. See pwm.txt in this directory for a description of
8   the cells format.

10 Optional 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)

17 Example:
18         pwm9: dmtimer-pwm@9 {
19                 compatible = "ti,omap-dmtimer-pwm";
20                 ti,timers = <&timer9>;
21                 #pwm-cells = <3>;
22         };
