Details

#pwm-cells

int

Number of items to expect in a pwm specifier

This property is required.

Constant value: 3

pinctrl-0

phandles

Pin configuration/s for the first state. Content is specific to the
selected pin controller driver implementation.

pinctrl-1

phandles

Pin configuration/s for the second state. See pinctrl-0.

pinctrl-2

phandles

Pin configuration/s for the third state. See pinctrl-0.

pinctrl-3

phandles

Pin configuration/s for the fourth state. See pinctrl-0.

pinctrl-4

phandles

Pin configuration/s for the fifth state. See pinctrl-0.

pinctrl-names

string-array

Names for the provided states. The number of names needs to match the
number of states.

index

int

flexpwm submodule index

This property is required.

run-in-wait

boolean

Enable for PWM to keep running in WAIT mode.

run-in-debug

boolean

Enable for PWM to keep running in debug mode.

nxp,prescaler

int

Clock prescaler at the input of the PWM.

This property is required.

Legal values: 1, 2, 4, 8, 16, 32, 64, 128

nxp,reload

string

Select how to load the buffered-registers with new values:
"immediate" - buffered-registers get loaded with new values as soon as LDOK bit is set;
"half-cycle" - registers loaded on a PWM half cycle;
"full-cycle" - registers loaded on a PWM full cycle;
"half-and-full-cycle" - registers loaded on a PWM half & full cycle.

Legal values: 'immediate', 'half-cycle', 'full-cycle', 'half-and-full-cycle'
