4Required properties:
5 - compatible =
6	"aspeed,ast2400-cf-fsi-master" for an AST2400 based system
7   or
8	"aspeed,ast2500-cf-fsi-master" for an AST2500 based system

10 - clock-gpios = <gpio-descriptor>;	: GPIO for FSI clock
11 - data-gpios = <gpio-descriptor>;	: GPIO for FSI data signal
12 - enable-gpios = <gpio-descriptor>;	: GPIO for enable signal
13 - trans-gpios = <gpio-descriptor>;	: GPIO for voltage translator enable
14 - mux-gpios = <gpio-descriptor>;	: GPIO for pin multiplexing with other
15                                          functions (eg, external FSI masters)
16 - memory-region = <phandle>;		: Reference to the reserved memory for
17                                          the ColdFire. Must be 2M aligned on
18					  AST2400 and 1M aligned on AST2500
19 - aspeed,sram = <phandle>;		: Reference to the SRAM node.
20 - aspeed,cvic = <phandle>;		: Reference to the CVIC node.
