* Legend: proper name = the GPIO line is used as GPIO |

* "[PER]" = pin is muxed for [peripheral] (not GPIO) |

* unrouted (not connected to any external pin) |

* LSEC = Low Speed External Connector |

* |
|
* Line names are taken from "hikey970-schematics.pdf" from HiSilicon. |
|
* |
|
* For the lines routed to the external connectors the |
|
* lines are named after the 96Boards CE Specification 1.0, |
|
* Appendix "Expansion Connector Signal Description". |
|
* |
|
* When the 96Board naming of a line and the schematic name of |
|
* the same line are in conflict, the 96Board specification |
|
* takes precedence, which means that the external UART on the |
|
* LSEC is named UART0 while the schematic and SoC names this |
|
* UART2. This is only for the informational lines i.e. "[FOO]", |
|
* the GPIO named lines "GPIO-A" thru "GPIO-L" are the only |
|
* ones actually used for GPIO. |
