TI SOC ECAP based APWM controller
|
|
|
|
Required properties:
|
|
- compatible: Must be "ti,<soc>-ecap".
|
|
for am33xx - compatible = "ti,am33xx-ecap";
|
|
for da850 - compatible = "ti,da850-ecap", "ti,am33xx-ecap";
|
|
- #pwm-cells: should be 3. See pwm.txt in this directory for a description of
|
|
the cells format. The PWM channel index ranges from 0 to 4. 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 ECAP:
|
|
"ecap<x>", <x> being the 0-based instance number from the HW spec
|
|
|
|
Example:
|
|
|
|
ecap0: ecap@0 { /* ECAP on am33xx */
|
|
compatible = "ti,am33xx-ecap";
|
|
#pwm-cells = <3>;
|
|
reg = <0x48300100 0x80>;
|
|
ti,hwmods = "ecap0";
|
|
};
|
|
|
|
ecap0: ecap@0 { /* ECAP on da850 */
|
|
compatible = "ti,da850-ecap", "ti,am33xx-ecap";
|
|
#pwm-cells = <3>;
|
|
reg = <0x306000 0x80>;
|
|
};
