-Nokia modem client bindings
-
-The Nokia modem HSI client follows the common HSI client binding
-and inherits all required properties. The following additional
-properties are needed by the Nokia modem HSI client:
-
-Required properties:
-- compatible:		Should be one of
-      "nokia,n900-modem"
-      "nokia,n950-modem"
-      "nokia,n9-modem"
-- hsi-channel-names:	Should contain the following strings
-      "mcsaab-control"
-      "speech-control"
-      "speech-data"
-      "mcsaab-data"
-- gpios:		Should provide a GPIO handler for each GPIO listed in
-                        gpio-names
-- gpio-names:		Should contain the following strings
-      "cmt_apeslpx" (for n900, n950, n9)
-      "cmt_rst_rq"  (for n900, n950, n9)
-      "cmt_en"      (for n900, n950, n9)
-      "cmt_rst"     (for n900)
-      "cmt_bsi"     (for n900)
-- interrupts:		Should be IRQ handle for modem's reset indication
-
-Example:
-
-&ssi_port {
-	modem: hsi-client {
-		compatible = "nokia,n900-modem";
-
-		pinctrl-names = "default";
-		pinctrl-0 = <&modem_pins>;
-
-		hsi-channel-ids = <0>, <1>, <2>, <3>;
-		hsi-channel-names = "mcsaab-control",
-				    "speech-control",
-				    "speech-data",
-				    "mcsaab-data";
-		hsi-speed-kbps = <55000>;
-		hsi-mode = "frame";
-		hsi-flow = "synchronized";
-		hsi-arb-mode = "round-robin";
-
-		interrupts-extended = <&gpio3 8 IRQ_TYPE_EDGE_FALLING>; /* 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 */

-			     "cmt_en",
-			     "cmt_rst",
-			     "cmt_bsi";
