Required properties:

• compatible: must be “brcm,bcm7038-pwm”
• reg: physical base address and length for this controller
• #pwm-cells: should be 2. See pwm.txt in this directory for a description
  of the cells format
• clocks: a phandle to the reference clock for this block which is fed through
  its internal variable clock frequency generator

Example:

pwm: pwm@f0408000 {
    compatible = "brcm,bcm7038-pwm";
    reg = <0xf0408000 0x28>;
    #pwm-cells = <2>;
    clocks = <&upg_fixed>;
};
