-* Clock bindings for Freescale i.MX31
-
-Required properties:
-- compatible: Should be "fsl,imx31-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.MX31
-clocks and IDs.
