TI SOC ECAP based APWM controller
|
|
|
|
Required properties:
|
|
- compatible: Must be "ti,<soc>-ecap".
|
|
for am33xx - compatible = "ti,am3352-ecap", "ti,am33xx-ecap";
|
|
for am4372 - compatible = "ti,am4372-ecap", "ti,am3352-ecap", "ti,am33xx-ecap";
|
|
for da850 - compatible = "ti,da850-ecap", "ti,am3352-ecap", "ti,am33xx-ecap";
|
|
for dra746 - compatible = "ti,dra746-ecap", "ti,am3352-ecap";
|
|
for 66ak2g - compatible = "ti,k2g-ecap", "ti,am3352-ecap";
|
|
for am654 - compatible = "ti,am654-ecap", "ti,am3352-ecap";
|
|
- #pwm-cells: should be 3. See pwm.yaml 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:
|
|
- clocks: Handle to the ECAP's functional clock.
|
|
- clock-names: Must be set to "fck".
|
|
|
|
Example:
|
|
|
|
ecap0: ecap@48300100 { /* ECAP on am33xx */
|
|
compatible = "ti,am3352-ecap", "ti,am33xx-ecap";
|
|
#pwm-cells = <3>;
|
|
reg = <0x48300100 0x80>;
|
|
clocks = <&l4ls_gclk>;
|
|
clock-names = "fck";
|
|
};
|
|
|
|
ecap0: ecap@48300100 { /* ECAP on am4372 */
|
|
compatible = "ti,am4372-ecap", "ti,am3352-ecap", "ti,am33xx-ecap";
|
|
#pwm-cells = <3>;
|
|
reg = <0x48300100 0x80>;
|
|
ti,hwmods = "ecap0";
|
|
clocks = <&l4ls_gclk>;
|
|
clock-names = "fck";
|
|
};
|
|
|
|
ecap0: ecap@1f06000 { /* ECAP on da850 */
|
|
compatible = "ti,da850-ecap", "ti,am3352-ecap", "ti,am33xx-ecap";
|
|
#pwm-cells = <3>;
|
|
reg = <0x1f06000 0x80>;
|
|
};

ecap0: ecap@4843e100 {

#pwm-cells = <3>;
|
|
reg = <0x4843e100 0x80>;
|
