The PWM client cells format is documented in the generic pwm.txt documentation and duplicated in all PWM driver bindings. Remove duplicate information and reference pwm.txt instead.

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>;
|
|
};
