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 {
compatible = "ti,dra746-ecap", "ti,am3352-ecap";
#pwm-cells = <3>;
reg = <0x4843e100 0x80>;
clocks = <&l4_root_clk_div>;
clock-names = "fck";
};
