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>;
    }
