* Legend: proper name = the GPIO line is used as GPIO
* NC = not connected (pin out but not routed from the chip to

* "[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.
