| 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>; |
| }; |
