+Broadcom Kona Family Clocks
+
+This binding is associated with Broadcom SoCs having "Kona" style
+clock control units (CCUs). A CCU is a clock provider that manages
+a set of clock signals. Each CCU is represented by a node in the
+device tree.
+
+This binding uses the common clock binding:
+ Documentation/devicetree/bindings/clock/clock-bindings.txt
+
+Required properties:
+- compatible
+ Shall have one of the following values:
+ - "brcm,bcm11351-root-ccu"
+ - "brcm,bcm11351-aon-ccu"
+ - "brcm,bcm11351-hub-ccu"
+ - "brcm,bcm11351-master-ccu"
+ - "brcm,bcm11351-slave-ccu"
+- reg
+ Shall define the base and range of the address space
+ containing clock control registers
+- #clock-cells
+ Shall have value <1>. The permitted clock-specifier values
+ are defined below.
+- clock-output-names
+ Shall be an ordered list of strings defining the names of
+ the clocks provided by the CCU.
+
+
+BCM281XX family SoCs use Kona CCUs. The following table defines
+the set of CCUs and clock specifiers for BCM281XX clocks. When
+a clock consumer references a clocks, its symbolic specifier
+(rather than its numeric index value) should be used. These
+specifiers are defined in "include/dt-bindings/clock/bcm281xx.h".
