1TI SOC ECAP based APWM controller 2 3Required properties: 4- compatible: Must be "ti,<soc>-ecap". 5 for am33xx - compatible = "ti,am3352-ecap", "ti,am33xx-ecap"; 6 for am4372 - compatible = "ti,am4372-ecap", "ti,am3352-ecap", "ti,am33xx-ecap"; 7 for da850 - compatible = "ti,da850-ecap", "ti,am3352-ecap", "ti,am33xx-ecap"; 8 for dra746 - compatible = "ti,dra746-ecap", "ti,am3352-ecap"; 9 for 66ak2g - compatible = "ti,k2g-ecap", "ti,am3352-ecap"; 10 for am654 - compatible = "ti,am654-ecap", "ti,am3352-ecap"; 11- #pwm-cells: should be 3. See pwm.yaml in this directory for a description of 12 the cells format. The PWM channel index ranges from 0 to 4. The only third 13 cell flag supported by this binding is PWM_POLARITY_INVERTED. 14- reg: physical base address and size of the registers map. 15 16Optional properties: 17- clocks: Handle to the ECAP's functional clock. 18- clock-names: Must be set to "fck". 19 20Example: 21 22ecap0: ecap@48300100 { /* ECAP on am33xx */ 23 compatible = "ti,am3352-ecap", "ti,am33xx-ecap"; 24 #pwm-cells = <3>; 25 reg = <0x48300100 0x80>; 26 clocks = <&l4ls_gclk>; 27 clock-names = "fck"; 28}; 29 30ecap0: ecap@48300100 { /* ECAP on am4372 */ 31 compatible = "ti,am4372-ecap", "ti,am3352-ecap", "ti,am33xx-ecap"; 32 #pwm-cells = <3>; 33 reg = <0x48300100 0x80>; 34 ti,hwmods = "ecap0"; 35 clocks = <&l4ls_gclk>; 36 clock-names = "fck"; 37}; 38 39ecap0: ecap@1f06000 { /* ECAP on da850 */ 40 compatible = "ti,da850-ecap", "ti,am3352-ecap", "ti,am33xx-ecap"; 41 #pwm-cells = <3>; 42 reg = <0x1f06000 0x80>; 43}; 44 45ecap0: ecap@4843e100 { 46 compatible = "ti,dra746-ecap", "ti,am3352-ecap"; 47 #pwm-cells = <3>; 48 reg = <0x4843e100 0x80>; 49 clocks = <&l4_root_clk_div>; 50 clock-names = "fck"; 51}; 52
