  *         "[PER]" = pin is muxed for [peripheral] (not GPIO)

  *         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
