+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";
+ };
+ };
