Perhaps better wording would be: - compatible: should contain "brcm,kona-pwm" > +- reg: physical base address and length of the controller's registers > +- clocks: phandle + clock specifier pair for the external clock > +- #pwm-cells: should be 3.

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. > +Refer to pwm/pwm.txt for generic pwm controller node properties. With the above, this line should go away. But still: "pwm controller" -> "PWM controller". Thierry
