- Device-tree bindings for gpio-based FSI master driver
- -----------------------------------------------------
- Required properties:
- - compatible = "fsi-master-gpio";
- - clock-gpios = <gpio-descriptor>; : GPIO for FSI clock
- - data-gpios = <gpio-descriptor>; : GPIO for FSI data signal
- Optional properties:
- - 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)
- - no-gpio-delays; : Don't add extra delays between GPIO
- accesses. This is useful when the HW
- GPIO block is running at a low enough
- frequency.
- Examples:
- fsi-master {
- compatible = "fsi-master-gpio", "fsi-master";
- clock-gpios = <&gpio 0>;
- data-gpios = <&gpio 1>;
- enable-gpios = <&gpio 2>;
- trans-gpios = <&gpio 3>;
- mux-gpios = <&gpio 4>;
- }
