| 68 | * GPIO name legend: proper name = the GPIO line is used as GPIO |
| 69 | * NC = not connected (pin out but not routed from the chip to |
| 70 | * anything the board) |
| 71 | * "[PER]" = pin is muxed for [peripheral] (not GPIO) |
| 72 | * LSEC = Low Speed External Connector |
| 73 | * HSEC = High Speed External Connector |
| 74 | * |
| 75 | * Line names are taken from the schematic "Schematics Bubblegum96" |
| 76 | * version v1.0 |
| 77 | * |
| 78 | * For the lines routed to the external connectors the |
| 79 | * lines are named after the 96Boards CE Specification 1.0, |
| 80 | * Appendix "Expansion Connector Signal Description". |
| 81 | * |
| 82 | * When the 96Boards naming of a line and the schematic name of |
| 83 | * the same line are in conflict, the 96Boards specification |
| 84 | * takes precedence, which means that the external UART on the |
| 85 | * LSEC is named UART0 while the schematic and SoC names this |
| 86 | * UART2. Only exception is the I2C lines for which the schematic |
| 87 | * naming has been preferred. This is only for the informational |
| 88 | * lines i.e. "[FOO]", the GPIO named lines "GPIO-A" thru "GPIO-L" |
| 89 | * are the only ones actually used for GPIO. |
