| 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"; |
| }; |
