0012 * GPIO name legend: proper name = the GPIO line is used as GPIO
0013 * NC = not connected (pin out but not routed from the chip to
0014 * anything the board)
0015 * "[PER]" = pin is muxed for [peripheral] (not GPIO)
0016 * LSEC = Low Speed External Connector
0017 * HSEC = High Speed External Connector
0018 *
0019 * Line names are taken from the schematic "sophon-edge-schematics"
0020 * version, 1.0210.
0021 *
0022 * For the lines routed to the external connectors the
0023 * lines are named after the 96Boards CE Specification 1.0,
0024 * Appendix "Expansion Connector Signal Description".
0025 *
0026 * When the 96Board naming of a line and the schematic name of
0027 * the same line are in conflict, the 96Board specification
0028 * takes precedence. This is only for the informational
0029 * lines i.e. "[FOO]", the GPIO named lines "GPIO-A" thru "GPIO-L"
0030 * are the only ones actually used for GPIO.
