| * "" = no idea, schematic doesn't say, could be |
| * unrouted (not connected to any external pin) |
| * LSEC = Low Speed External Connector |
| * HSEC = High 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 |
