    1 Device-tree bindings for ColdFire offloaded gpio-based FSI master driver
    2 ------------------------------------------------------------------------
    3 
    4 Required 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
    9 
   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.
   21 
   22 Examples:
   23 
   24     fsi-master {
   25         compatible = "aspeed,ast2500-cf-fsi-master", "fsi-master";
   26 
   27         clock-gpios = <&gpio 0>;
   28         data-gpios = <&gpio 1>;
   29         enable-gpios = <&gpio 2>;
   30         trans-gpios = <&gpio 3>;
   31         mux-gpios = <&gpio 4>;
   32 
   33         memory-region = <&coldfire_memory>;
   34         aspeed,sram = <&sram>;
   35         aspeed,cvic = <&cvic>;
   36     }
