3*4882a593SmuzhiyunThis controller has 4 channels.
4*4882a593Smuzhiyun
5*4882a593SmuzhiyunRequired Properties :
6*4882a593Smuzhiyun- compatible: must be "brcm,iproc-pwm"
7*4882a593Smuzhiyun- reg: physical base address and length of the controller's registers
8*4882a593Smuzhiyun- clocks: phandle + clock specifier pair for the external clock
9*4882a593Smuzhiyun- #pwm-cells: Should be 3. See pwm.yaml in this directory for a
10*4882a593Smuzhiyun  description of the cells format.
