-- #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.
+- #pwm-cells: should be 3. See pwm.txt in this directory for a description of
+ the cells format. The PWM channel index ranges from 0 to 4. The only third
+ cell flag supported by this binding is PWM_POLARITY_INVERTED.
