1 Atmel TCB PWM controller
4 - compatible: should be "atmel,tcb-pwm"
5 - #pwm-cells: Should be 3. The first cell specifies the per-chip index
6 of the PWM to use, the second cell is the period in nanoseconds and
7 bit 0 in the third cell is used to encode the polarity of PWM output.
8 Set bit 0 of the third cell in PWM specifier to 1 for inverse polarity &
9 set to 0 for normal polarity.
10 - tc-block: The Timer Counter block to use as a PWM chip.
