| 2 | ----------------------------------------------------- |
| 3 | |
| 4 | Required properties: |
| 5 | - compatible = "fsi-master-gpio"; |
| 6 | - clock-gpios = <gpio-descriptor>; : GPIO for FSI clock |
| 7 | - data-gpios = <gpio-descriptor>; : GPIO for FSI data signal |
| 8 | |
| 9 | Optional properties: |
| 10 | - enable-gpios = <gpio-descriptor>; : GPIO for enable signal |
| 11 | - trans-gpios = <gpio-descriptor>; : GPIO for voltage translator enable |
| 12 | - mux-gpios = <gpio-descriptor>; : GPIO for pin multiplexing with other |
| 13 | functions (eg, external FSI masters) |
| 14 | - no-gpio-delays; : Don't add extra delays between GPIO |
| 15 | accesses. This is useful when the HW |
| 16 | GPIO block is running at a low enough |
| 17 | frequency. |
| 18 | |
| 19 | Examples: |
| 20 | |
| 21 | fsi-master { |
| 22 | compatible = "fsi-master-gpio", "fsi-master"; |
| 23 | clock-gpios = <&gpio 0>; |
| 24 | data-gpios = <&gpio 1>; |
| 25 | enable-gpios = <&gpio 2>; |
| 26 | trans-gpios = <&gpio 3>; |
| 27 | mux-gpios = <&gpio 4>; |
| 28 | } |
