4*c66ec88fSEmmanuel Vadot
5*c66ec88fSEmmanuel VadotRequired Properties :
6*c66ec88fSEmmanuel Vadot- compatible: must be "brcm,iproc-pwm"
7*c66ec88fSEmmanuel Vadot- reg: physical base address and length of the controller's registers
8*c66ec88fSEmmanuel Vadot- clocks: phandle + clock specifier pair for the external clock
9*c66ec88fSEmmanuel Vadot- #pwm-cells: Should be 3. See pwm.yaml in this directory for a
10*c66ec88fSEmmanuel Vadot  description of the cells format.
