+Clock bindings for ARM Integrator Core Module clocks
+
+Auxilary Oscillator Clock
+
+This is a configurable clock fed from a 24 MHz chrystal,
+used for generating e.g. video clocks. It is located on the
+core module and there is only one of these.
+
+This clock node *must* be a subnode of the core module, since
+it obtains the base address for it's address range from its
+parent node.
+
+
+Required properties:
+- compatible: must be "arm,integrator-cm-auxosc"
+- #clock-cells: must be <0>
+
+Optional properties:
+- clocks: parent clock(s)
+
+Example:
+
+core-module@10000000 {
+ xtal24mhz: xtal24mhz@24M {
+ #clock-cells = <0>;
+ compatible = "fixed-clock";
+ clock-frequency = <24000000>;
+ };
+ auxosc: cm_aux_osc@25M {
+ #clock-cells = <0>;
+ compatible = "arm,integrator-cm-auxosc";
+ clocks = <&xtal24mhz>;
+ };
+};
