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>;
};
