 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.
