This is somewhat inconsistent because the example below clearly doesn't
set the compatible property to "brcm,kona-pwm". Perhaps better wording
would be:
- compatible: should contain "brcm,kona-pwm"

Please use the canonical description for this:
- #pwm-cells: Should be 3. See pwm.txt in this directory for a
description of the cells format.

With the above, this line should go away. But still: "pwm controller" ->
"PWM controller".
