-NXP LPC32xx Clock Controller
-
-Required properties:
-- compatible: should be "nxp,lpc3220-clk"
-- reg:  should contain clock controller registers location and length
-- #clock-cells: must be 1, the cell holds id of a clock provided by the
-  clock controller
-- clocks: phandles of external oscillators, the list must contain one
-  32768 Hz oscillator and may have one optional high frequency oscillator
-- clock-names: list of external oscillator clock names, must contain
-  "xtal_32k" and may have optional "xtal"
-
-Examples:
-
-       /* System Control Block */
-       scb {
-               compatible = "simple-bus";
-               ranges = <0x0 0x040004000 0x00001000>;
-               #address-cells = <1>;
-               #size-cells = <1>;
-
-               clk: clock-controller@0 {
-                       compatible = "nxp,lpc3220-clk";
-                       reg = <0x00 0x114>;
-                       #clock-cells = <1>;
-
-                       clocks = <&xtal_32k>, <&xtal>;
-                       clock-names = "xtal_32k", "xtal";
-               };
