ChangeLog v5->v6:
- The dependency on pdata clocks has been removed,
  and the dtsi adapted accordinly.
- Adaptation to the for-next branch of Shawn Guo at
  git://git.linaro.org/people/shawnguo/linux-2.6.git for-next
- imx35-dt.c: very small whitespace cleanup.
- Kconfig: The selection of IMX_HAVE_PLATFORM_* has been removed.
- dtsi: The nodes were reordered alphabetically.
- dtsi: The aliases have been reordered alphabetically.
- Shawn Guo was added in the Cc.

+* Clock bindings for Freescale i.MX35
+
+Required properties:
+- compatible: Should be "fsl,imx35-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.MX35
+clocks and IDs.
