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>; }
