Subject: dt-bindings: Document img,boston-clock binding
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
+
+The device node must be a child node of the syscon node corresponding to the
+Boston system's platform registers.
+
+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>
+
+Example:
+
+ system-controller@17ffd000 {
+ compatible = "img,boston-platform-regs", "syscon";
+ reg = <0x17ffd000 0x1000>;
+
+ clk_boston: clock {
+ compatible = "img,boston-clock";
+ #clock-cells = <1>;
+ };
+ };
+
+ uart0: uart@17ffe000 {
+ /* ... */
+ clocks = <&clk_boston BOSTON_CLK_SYS>;
+ };
