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>; |
|
}
