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
ecap0: ecap@0 {
compatible = "ti,am33xx-ecap";
#pwm-cells = <3>;
reg = <0x48300100 0x80>;
ti,hwmods = "ecap0";
