+* Clock bindings for Freescale i.MX27
+
+Required properties:
+- compatible: Should be "fsl,imx27-ccm"
+- reg: Address and length of the register set
+- interrupts: Should contain CCM interrupt
+- #clock-cells: Should be <1>
+
+The clock consumer should specify the desired clock by having the clock
+ID in its "clocks" phandle cell. The following is a full list of i.MX27
+clocks and IDs.
