Now that the node name has been changed from ehrpwm to pwm the document should show this proper usage. Also change the unit address in the example from 0 to the proper physical address value that should be used.

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: pwm@48300200 { /* EHRPWM on am33xx */
|
|
compatible = "ti,am33xx-ehrpwm";
|
|
#pwm-cells = <3>;
|
|
reg = <0x48300200 0x100>;
|
|
ti,hwmods = "ehrpwm0";
|
|
};
|
|
|
|
ehrpwm0: pwm@300000 { /* EHRPWM on da850 */
|
|
compatible = "ti,da850-ehrpwm", "ti,am33xx-ehrpwm";
|
|
#pwm-cells = <3>;
|
|
reg = <0x300000 0x2000>;
|
|
};
