1 | TI SOC EHRPWM based PWM controller |
| 2 | ||
| 3 | Required properties: | |
| bdd7cf97 PA |
4 | - compatible: Must be "ti,<soc>-ehrpwm". |
| 5 | for am33xx - compatible = "ti,am33xx-ehrpwm"; | |
| 6 | for da850 - compatible = "ti,da850-ehrpwm", "ti,am33xx-ehrpwm"; | |
| ebeec0af LP |
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. | |
| 53ad9e8d PA |
10 | - reg: physical base address and size of the registers map. |
| 11 | ||
| 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 | |
| 15 | ||
| 16 | Example: | |
| 17 | ||
| bdd7cf97 | 18 | ehrpwm0: ehrpwm@0 { /* EHRPWM on am33xx */ |
| 53ad9e8d PA |
19 | compatible = "ti,am33xx-ehrpwm"; |
| 20 | #pwm-cells = <3>; | |
| 21 | reg = <0x48300200 0x100>; | |
| 22 | ti,hwmods = "ehrpwm0"; | |
| 23 | }; | |
| bdd7cf97 PA |
24 | |
| 25 | ehrpwm0: ehrpwm@0 { /* EHRPWM on da850 */ | |
| 26 | compatible = "ti,da850-ehrpwm", "ti,am33xx-ehrpwm"; | |
| 27 | #pwm-cells = <3>; | |
| 28 | reg = <0x300000 0x2000>; | |
| 29 | }; |
