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>;
}
