* Clock bindings for Freescale i.MX28



Required properties:

- compatible: Should be "fsl,imx28-clkctrl"

- reg: Address and length of the register set

- #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.MX28

clocks and IDs.
