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"; |
|
};
