+Broadcom BCM7038 PWM controller (BCM7xxx Set Top Box PWM controller)
+
+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@...08000 {
+ compatible = "brcm,bcm7038-pwm";
+ reg = <0xf0408000 0x28>;
+ #pwm-cells = <2>;
+ clocks = <&upg_fixed>;
+ };
