   1 * Clock bindings for Freescale i.MX28
   2
   3 Required properties:
   4 - compatible: Should be "fsl,imx28-clkctrl"
   5 - reg: Address and length of the register set
   6 - #clock-cells: Should be <1>
   7
   8 The clock consumer should specify the desired clock by having the clock
   9 ID in its "clocks" phandle cell.  The following is a full list of i.MX28
  10 clocks and IDs.
