1TI SOC EHRPWM based PWM controller 2 3Required 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. 11 12Optional 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 15 16Example: 17 18ehrpwm0: ehrpwm@0 { /* EHRPWM on am33xx */ 19 compatible = "ti,am33xx-ehrpwm"; 20 #pwm-cells = <3>; 21 reg = <0x48300200 0x100>; 22 ti,hwmods = "ehrpwm0"; 23}; 24 25ehrpwm0: ehrpwm@0 { /* EHRPWM on da850 */ 26 compatible = "ti,da850-ehrpwm", "ti,am33xx-ehrpwm"; 27 #pwm-cells = <3>; 28 reg = <0x300000 0x2000>; 29}; 30
