| 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>; |
| } |
