   1 * Clock bindings for Freescale i.MX25
   2
   3 Required properties:
   4 - compatible: Should be "fsl,imx25-ccm"
   5 - reg: Address and length of the register set
   6 - interrupts: Should contain CCM interrupt
   7 - #clock-cells: Should be <1>
   8
   9 The clock consumer should specify the desired clock by having the clock
  10 ID in its "clocks" phandle cell.  The following is a full list of i.MX25
  11 clocks and IDs.
