Merge tag 'arm-soc/for-3.18/cygnus-dts-v9' of http://github.com/brcm/linux into next/dt

Merge "Broadcom Cygnus SoC Device Tree changes" from Florian Fianelli:

This patchset contains initial support for Broadcom's Cygnus SoC based on our
iProc architecture. Initial support is minimal and includes just the mach
platform code, clock driver, and a basic device tree configuration. Peripheral
drivers will be submitted soon, as will device tree configurations for other
Cygnus board variants.

These are the Device Tree changes

+Broadcom Cygnus Clocks
+
+This binding uses the common clock binding:
+Documentation/devicetree/bindings/clock/clock-bindings.txt
+
+Currently various "fixed" clocks are declared for peripheral drivers that use
+the common clock framework to reference their core clocks. Proper support of
+these clocks will be added later
+
+Device tree example:
+
+	clocks {
+		#address-cells = <1>;
+		#size-cells = <1>;
+		ranges;
+
+		osc: oscillator {
+			compatible = "fixed-clock";
+			#clock-cells = <1>;
+			clock-frequency = <25000000>;
+		};
+
+		apb_clk: apb_clk {
+			compatible = "fixed-clock";
+			#clock-cells = <0>;
+			clock-frequency = <1000000000>;
+		};
+
+		periph_clk: periph_clk {
+			compatible = "fixed-clock";
+			#clock-cells = <0>;
+			clock-frequency = <500000000>;
+		};
+	};
