Add device tree binding documentation for the clocks provided by the
MIPS Boston development board from Imagination Technologies, and a
header file describing the available clocks for use by device trees &
driver.

+Binding for Imagination Technologies MIPS Boston clock sources.
+
+This binding uses the common clock binding[1].
+
+[1] Documentation/devicetree/bindings/clock/clock-bindings.txt
+
+Required properties:
+- compatible : Should be "img,boston-clock".
+- #clock-cells : Should be set to 1.
+  Values available for clock consumers can be found in the header file:
+    <dt-bindings/clock/boston-clock.h>
+- regmap : Phandle to the Boston platform register system controller.
+  This should contain a phandle to the system controller node covering the
+  platform registers provided by the Boston board.
+
+Example:
+
+	clk_boston: clock {
+		compatible = "img,boston-clock";
+		#clock-cells = <1>;
+		regmap = <&plat_regs>;
+	};
+
+	uart0: uart@17ffe000 {
+		/* ... */
+		clocks = <&clk_boston BOSTON_CLK_SYS>;
+	};
