| 13 | description: |
| 14 | The PMIC GLINK service, running on a coprocessor on some modern Qualcomm |
| 15 | platforms and implement USB Type-C handling and battery management. This |
| 16 | binding describes the component in the OS used to communicate with the |
| 17 | firmware and connect it's resources to those described in the Devicetree, |
| 18 | particularly the USB Type-C controllers relationship with USB and DisplayPort |
| 19 | components. |

| 39 | description: Array of input gpios for the Type-C connector orientation indication. |
| 40 | The GPIO indication is used to detect the orientation of the Type-C connector. |
| 41 | The array should contain a gpio entry for each PMIC Glink connector, in reg order. |
| 42 | It is defined that GPIO active level means "CC2" or Reversed/Flipped orientation. |
