1 TI SOC EHRPWM based PWM controller
3 Required properties:
4 - compatible: Must be "ti,<soc>-ehrpwm".
5   for am33xx - compatible = "ti,am33xx-ehrpwm";
6   for da850  - compatible = "ti,da850-ehrpwm", "ti,am33xx-ehrpwm";
7 - #pwm-cells: should be 3. See pwm.txt in this directory for a description of
8   the cells format. The only third cell flag supported by this binding is
9   PWM_POLARITY_INVERTED.
10 - reg: physical base address and size of the registers map.
12 Optional properties:
13 - ti,hwmods: Name of the hwmod associated to the EHRPWM:
14   "ehrpwm<x>", <x> being the 0-based instance number from the HW spec
16 Example:
18 ehrpwm0: ehrpwm@0 { /* EHRPWM on am33xx */
19         compatible = "ti,am33xx-ehrpwm";
20         #pwm-cells = <3>;
21         reg = <0x48300200 0x100>;
22         ti,hwmods = "ehrpwm0";
25 ehrpwm0: ehrpwm@0 { /* EHRPWM on da850 */
26         compatible = "ti,da850-ehrpwm", "ti,am33xx-ehrpwm";
27         #pwm-cells = <3>;
28         reg = <0x300000 0x2000>;
