    1 Device-tree bindings for gpio-based FSI master driver
    2 -----------------------------------------------------
    3 
    4 Required properties:
    5  - compatible = "fsi-master-gpio";
    6  - clock-gpios = <gpio-descriptor>;     : GPIO for FSI clock
    7  - data-gpios = <gpio-descriptor>;      : GPIO for FSI data signal
    8 
    9 Optional properties:
   10  - enable-gpios = <gpio-descriptor>;    : GPIO for enable signal
   11  - trans-gpios = <gpio-descriptor>;     : GPIO for voltage translator enable
   12  - mux-gpios = <gpio-descriptor>;       : GPIO for pin multiplexing with other
   13                                           functions (eg, external FSI masters)
   14  - no-gpio-delays;                      : Don't add extra delays between GPIO
   15                                           accesses. This is useful when the HW
   16                                           GPIO block is running at a low enough
   17                                           frequency.

   19 Examples:
   20 
   21     fsi-master {
   22         compatible = "fsi-master-gpio", "fsi-master";
   23         clock-gpios = <&gpio 0>;
   24         data-gpios = <&gpio 1>;
   25         enable-gpios = <&gpio 2>;
   26         trans-gpios = <&gpio 3>;
   27         mux-gpios = <&gpio 4>;
   28     }
