+Nokia Cellular Modem (CMT) bindings
+
+Required properties:
+- compatible:		Should include "nokia,cmt".
+- interrupts:		Interrupt specifier for the cmt reset irq.
+- gpio-names:		Contains the values "cmt_apeslpx", "cmt_rst_rq",
+			"cmt_en", "cmt_rst" and "cmt_bsi".
+- gpios:		Contains gpio information for each entry in gpio-names.
+
+Example for Nokia N900:
+
+cmt: nokia-cmt {
+	compatible = "nokia,cmt";
+
+	interrupt-parent = <&gpio3>;
+	interrupts = <8 IRQ_TYPE_EDGE_FALLING>; /* gpio line 72 */
+
+	gpios = <&gpio3  6 GPIO_ACTIVE_HIGH>, /* 70 */
+		<&gpio3  9 GPIO_ACTIVE_HIGH>, /* 73 */
+		<&gpio3 10 GPIO_ACTIVE_HIGH>, /* 74 */
+		<&gpio3 11 GPIO_ACTIVE_HIGH>, /* 75 */
+		<&gpio5 29 GPIO_ACTIVE_HIGH>; /* 157 */
+	gpio-names = "cmt_apeslpx",
+		     "cmt_rst_rq",
+		     "cmt_en",
+		     "cmt_rst",
+		     "cmt_bsi";
+};
