+Intel XScale PXA255 development platform (Lubbock).
+
+This regroups all the CPLDs on the Lubbock motherboard, providing interrupt
+muxing, leds handling, ...
+
+Required properties:
+  - compatible : should be "intel,lubbock-cplds"
+
+  - interrupts : The first interrupt is the SoC input interrupt connected to the
+                 lubbock IO board interrupt multiplexer output. The only known
+                 working conifguration is GPIO0 on the PXA25X SoC.
+
+Optional properties:
+  - interrupts : The second optional interrupt is the base of the interrupts
+                 multiplexed by the lubbock motherboard. If unspecified, the
+                 range is fully dynamic, and the irqdomain will generate its
+                 interrupt base on the fly.
+
+Example:
+
+mb: lubbock-mb@0 {
+	compatible = "intel,lubbock-cplds";
+	interrupts = <0 IRQ_TYPE_EDGE_FALLING 400 IRQ_TYPE_NONE>;
+	#interrupt-cells = <2>;
+	interrupt-parent = <&pxairq>;
