| 12 | * GPIO name legend: proper name = the GPIO line is used as GPIO |
| 13 | * NC = not connected (pin out but not routed from the chip to |
| 14 | * anything the board) |
| 15 | * "[PER]" = pin is muxed for [peripheral] (not GPIO) |
| 16 | * LSEC = Low Speed External Connector |
| 17 | * HSEC = High Speed External Connector |
| 18 | * |
| 19 | * Line names are taken from the schematic "sophon-edge-schematics" |
| 20 | * version, 1.0210. |
| 21 | * |
| 22 | * For the lines routed to the external connectors the |
| 23 | * lines are named after the 96Boards CE Specification 1.0, |
| 24 | * Appendix "Expansion Connector Signal Description". |
| 25 | * |
| 26 | * When the 96Board naming of a line and the schematic name of |
| 27 | * the same line are in conflict, the 96Board specification |
| 28 | * takes precedence. This is only for the informational |
| 29 | * lines i.e. "[FOO]", the GPIO named lines "GPIO-A" thru "GPIO-L" |
| 30 | * are the only ones actually used for GPIO. |
