+Device-tree bindings for ColdFire offloaded gpio-based FSI master driver
+------------------------------------------------------------------------
+
+Required properties:
+ - compatible =
+ "aspeed,ast2400-cf-fsi-master" for an AST2400 based system
+ or
+ "aspeed,ast2500-cf-fsi-master" for an AST2500 based system
+
+ - clock-gpios = <gpio-descriptor>; : GPIO for FSI clock
+ - data-gpios = <gpio-descriptor>; : GPIO for FSI data signal
+ - 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)
+ - memory-region = <phandle>; : Reference to the reserved memory for
+ the ColdFire. Must be 2M aligned on
+ AST2400 and 1M aligned on AST2500
+ - aspeed,sram = <phandle>; : Reference to the SRAM node.
+ - aspeed,cvic = <phandle>; : Reference to the CVIC node.
+
+Examples:
+
+ fsi-master {
+ compatible = "aspeed,ast2500-cf-fsi-master", "fsi-master";
+
+ clock-gpios = <&gpio 0>;
+ data-gpios = <&gpio 1>;
+ enable-gpios = <&gpio 2>;
+ trans-gpios = <&gpio 3>;
+ mux-gpios = <&gpio 4>;
+
+ memory-region = <&coldfire_memory>;
+ aspeed,sram = <&sram>;
+ aspeed,cvic = <&cvic>;
+ }
