+Device Tree Clock bindings for Calxeda highbank platform
+
+This binding uses the common clock binding[1].
+
+[1] Documentation/devicetree/bindings/clock/clock-bindings.txt
+
+Required properties:
+- compatible : shall be one of the following:
+	"calxeda,hb-pll-clock" - for a PLL clock
+	"calxeda,hb-a9periph-clock" - The A9 peripheral clock divided from the
+		A9 clock.
+	"calxeda,hb-a9bus-clock" - The A9 bus clock divided from the A9 clock.
+	"calxeda,hb-emmc-clock" - Divided clock for MMC/SD controller.
+- reg : shall be the control register offset from SYSREGs base for the clock.
+- clocks : shall be the input parent clock phandle for the clock. This is
+	either an oscillator or a pll output.
+- #clock-cells : from common clock binding; shall be set to 0.
