+* 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.

ChangeLog v2->v3:
- This patch was splitted, the part that enabled the display, the audio, and
the touchscreen was removed and will be submited in a new patch
serie(because they depend on changes touching other subsystems).
- The pads for the tsc2007 were moved in the imx35-eukrea-cpuimx35.dtsi file
because the tsc2007 touchscreen controller is on the cpuimx35 module and not
on its baseboard.

Please drop the graphics nodes for now until we have the IPU bindings
sorted out and merged.
