+Broadcom's PWM Controller Device Tree bindings
+
+Broadcom's Kona PWM Controller has 6 channels
+
+Required Properties :
+- compatible: should be "brcm,kona-pwm"
+- reg: physical base address and length of the controller's registers
+- clocks: clock specifier for the kona pwm external clock
+- #pwm-cells: should be 2. The first cell specifies the per-chip index
+ of the PWM to use and the second cell is the period in nanoseconds.
+
+Refer to pwm/pwm.txt for generic pwm controller node properties.
+
+Refer to clocks/clock-bindings.txt for generic clock consumer
+properties
+
+Example:
+
+pwm: pwm@3e01a000 {
+ compatible = "brcm,bcm11351-pwm", "brcm,kona-pwm";
+ reg = <0x3e01a000 0xc4>;
+ clocks = <&pwm_clk>;
+ #pwm-cells = <2>;
+};
