+Device-tree bindings for gpio-based FSI master driver
+-----------------------------------------------------
+
+Required properties:
+ - compatible = "fsi-master-gpio";
+ - clock-gpios = <gpio-descriptor>; : GPIO for FSI clock
+ - data-gpios = <gpio-descriptor>; : GPIO for FSI data signal
+
+Optional properties:
+ - enable-gpios = <gpio-descriptor>; : GPIO for enable signal
+ - trans-gpios = <gpio-descriptor>; : GPIO for voltage translator enable
+ - mux-gpios = <gpio-descriptor>; : GPIO for pin multiplexing with other
+ functions (eg, external FSI masters)
+
+Examples:
+
+ fsi-master {
+ compatible = "fsi-master-gpio", "fsi-master";
+ clock-gpios = <&gpio 0>;
+ data-gpios = <&gpio 1>;
+ enable-gpios = <&gpio 2>;
+ trans-gpios = <&gpio 3>;
+ mux-gpios = <&gpio 4>;
+ }
