TI SOC ECAP based APWM controller
|
||
|
|
|
||
|
|
Required properties:
|
||
|
|
- compatible: Must be "ti,am33xx-ecap"
|
||
|
|
- #pwm-cells: Should be 3. Number of cells being used to specify PWM property.
|
||
|
|
First cell specifies the per-chip index of the PWM to use, the second
|
||
|
|
cell is the period in nanoseconds and bit 0 in the third cell is used to
|
||
|
|
encode the polarity of PWM output. Set bit 0 of the third in PWM specifier
|
||
|
|
to 1 for inverse polarity & set to 0 for normal polarity.
|
||
|
|
- reg: physical base address and size of the registers map.
|
||
|
|
|
||
|
|
Optional properties:
|
||
|
|
- ti,hwmods: Name of the hwmod associated to the ECAP:
|
||
|
|
"ecap<x>", <x> being the 0-based instance number from the HW spec
|
||
|
|
|
||
|
|
Example:
|
||
|
|
|
||
|
|
ecap0: ecap@0 {
|
||
|
|
compatible = "ti,am33xx-ecap";
|
||
|
|
#pwm-cells = <3>;
|
||
|
|
reg = <0x48300100 0x80>;
|
||
|
|
ti,hwmods = "ecap0";
|
||
|
|
};
