| TI SOC EHRPWM based PWM controller |
| |
| Required properties: |
| - compatible : Must be "ti,am33xx-ehrpwm" |
| - #pwm-cells: Should be 3. Number of cells being used to specify PWM property. |
| First cell specifies the per-chip index of the PWM to use, the second |
| cell is the period in nanoseconds and bit 0 in the third cell is used to |
| encode the polarity of PWM output. Set bit 0 of the third in PWM specifier |
| to 1 for inverse polarity & set to 0 for normal polarity. |
| - 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 { |
| compatible = "ti,am33xx-ehrpwm"; |
| #pwm-cells = <3>; |
| reg = <0x48300200 0x100>; |
| ti,hwmods = "ehrpwm0"; |
| }; |
