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)
|
|
|
|
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>;
|
|
}
