+Freescale Localbus UPM programmed to work with NAND flash
+
+Required properties:
+- compatible : "fsl,upm-nand".
+- reg : should specify localbus chip select and size used for the chip.
+- fsl,upm-addr-offset : UPM pattern offset for the address latch.
+- fsl,upm-cmd-offset : UPM pattern offset for the command latch.
+- gpios : may specify optional GPIO connected to the Ready-Not-Busy pin.
+
+Example:
+
+upm@1,0 {
+        compatible = "fsl,upm-nand";
+        reg = <1 0 1>;
+        fsl,upm-addr-offset = <16>;
+        fsl,upm-cmd-offset = <8>;
+        gpios = <&qe_pio_e 18 0>;
+
+        flash {
+                #address-cells = <1>;
+                #size-cells = <1>;
+                compatible = "...";
+
+                partition@0 {
+                        ...
+                };
+        };
+};
