* 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.
