- 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";
- - #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:
- - 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";
- };
