* Clock bindings for Freescale i.MX23

Required properties:
- compatible: Should be "fsl,imx23-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.MX23
clocks and IDs.

Examples:

	compatible = "fsl,imx23-clkctrl";
	reg = <0x80040000 0x2000>;
	#clock-cells = <1>;
	clock-output-names =
		...
		"uart",		/* 32 */
		...
		"end_of_list";
};

auart0: serial@8006c000 {
	compatible = "fsl,imx23-auart";
	reg = <0x8006c000 0x2000>;
	interrupts = <24 25 23>;
