+Broadcom iProc Family Clocks
+
+This binding uses the common clock binding:
+    Documentation/devicetree/bindings/clock/clock-bindings.txt
+
+The iProc clock controller manages clocks that are common to the iProc family.
+An SoC from the iProc family may have several PPLs, e.g., ARMPLL, GENPLL,
+LCPLL0, MIPIPLL, and etc., all derived from an onboard crystal. Each PLL
+comprises of several leaf clocks
+
+Required properties for a PLL and its leaf clocks:
+
+- compatible:
+    Should have a value of the form "brcm,<soc>-<pll>". For example, GENPLL on
+Cygnus has a compatible string of "brcm,cygnus-genpll"
+
+- #clock-cells:
+    Have a value of <1> since there are more than 1 leaf clock of a given PLL
+
+- reg:
+    Define the base and range of the I/O address space that contain the iProc
+clock control registers required for the PLL
+
+- clocks:
+    The input parent clock phandle for the PLL. For most iProc PLLs, this is an
+onboard crystal with a fixed rate
+
+- clock-output-names:
+    An ordered list of strings defining the names of the clocks
+
+Example:
+
+	osc: oscillator {
+		#clock-cells = <0>;
+		compatible = "fixed-clock";
+		clock-frequency = <25000000>;
+	};
+
+	genpll: genpll {
+		#clock-cells = <1>;
+		compatible = "brcm,cygnus-genpll";
+		reg = <0x0301d000 0x2c>, <0x0301c020 0x4>;
+		clocks = <&osc>;
+		clock-output-names = "genpll", "axi21", "250mhz", "ihost_sys",
+				     "enet_sw", "audio_125", "can";
+	};
+
+Required properties for ASIU clocks:
+
+ASIU clocks are a special case. These clocks are derived directly from the
+reference clock of the onboard crystal
+
+- compatible:
+    Should have a value of the form "brcm,<soc>-asiu-clk". For example, ASIU
+clocks for Cygnus have a compatible string of "brcm,cygnus-asiu-clk"
+
+- #clock-cells:
+    Have a value of <1> since there are more than 1 ASIU clocks
+
+- reg:
+    Define the base and range of the I/O address space that contain the iProc
+clock control registers required for ASIU clocks
+
+- clocks:
+    The input parent clock phandle for the ASIU clock, i.e., the onboard
+crystal
+
+- clock-output-names:
+    An ordered list of strings defining the names of the ASIU clocks
+
+Example:
+
+	osc: oscillator {
+		#clock-cells = <0>;
+		compatible = "fixed-clock";
+		clock-frequency = <25000000>;
+	};
+
+	asiu_clks: asiu_clks {
+		#clock-cells = <1>;
+		compatible = "brcm,cygnus-asiu-clk";
+		reg = <0x0301d048 0xc>, <0x180aa024 0x4>;
+		clocks = <&osc>;
+		clock-output-names = "keypad", "adc/touch", "pwm";
+	};
