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

30 * are the only ones actually used for GPIO.
