- TI SOC EHRPWM based PWM controller
- Required properties:
- - compatible: Must be "ti,<soc>-ehrpwm".
- for am33xx - compatible = "ti,am33xx-ehrpwm";
- for da850 - compatible = "ti,da850-ehrpwm", "ti,am33xx-ehrpwm";
- - #pwm-cells: should be 3. See pwm.txt in this directory for a description of
- the cells format. The only third cell flag supported by this binding is
- PWM_POLARITY_INVERTED.
- - reg: physical base address and size of the registers map.
- Optional properties:
- - ti,hwmods: Name of the hwmod associated to the EHRPWM:
- "ehrpwm<x>", <x> being the 0-based instance number from the HW spec
- Example:
- ehrpwm0: ehrpwm@0 { /* EHRPWM on am33xx */
- compatible = "ti,am33xx-ehrpwm";
- #pwm-cells = <3>;
- reg = <0x48300200 0x100>;
- ti,hwmods = "ehrpwm0";
- };
- ehrpwm0: ehrpwm@0 { /* EHRPWM on da850 */
- compatible = "ti,da850-ehrpwm", "ti,am33xx-ehrpwm";
- #pwm-cells = <3>;
- reg = <0x300000 0x2000>;
- };
