/*
 * Legend: proper name = the GPIO line is used as GPIO
 *         NC = not connected (pin out but not routed from the chip to
 *              anything the board)
 *         "[PER]" = pin is muxed for [peripheral] (not GPIO)
 *         "" = no idea, schematic doesn't say, could be
 *              unrouted (not connected to any external pin)
 *         LSEC = Low Speed External Connector
 *         HSEC = High Speed External Connector
 *
 * Line names are taken from "HiKey 960 Board ver A" schematics
 * from Huawei. The 40 pin low speed expansion connector is named
 * J2002 63453-140LF.
 *
 * For the lines routed to the external connectors the
 * lines are named after the 96Boards CE Specification 1.0,
 * Appendix "Expansion Connector Signal Description".
 *
 * When the 96Board naming of a line and the schematic name of
 * the same line are in conflict, the 96Board specification
 * takes precedence, which means that the external UART on the
 * LSEC is named UART0 while the schematic and SoC names this
 * UART3. This is only for the informational lines i.e. "[FOO]",
 * the GPIO named lines "GPIO-A" thru "GPIO-L" are the only
 * ones actually used for GPIO.
