Atmel TCB PWM controller
|
||
|
|
|
||
|
|
Required properties:
|
||
|
|
- compatible: should be "atmel,tcb-pwm"
|
||
|
|
- #pwm-cells: Should be 3. The 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 cell in PWM specifier to 1 for inverse polarity &
|
||
|
|
set to 0 for normal polarity.
|
||
|
|
- tc-block: The Timer Counter block to use as a PWM chip.
|
||
|
|
|
||
|
|
Example:
|
||
|
|
|
||
|
|
pwm {
|
||
|
|
compatible = "atmel,tcb-pwm";
|
||
|
|
#pwm-cells = <3>;
|
||
|
|
tc-block = <1>;
|
||
|
|
};
