+ *         HSEC = High Speed External Connector
+ *
+ * Line names are taken from "hikey970-schematics.pdf" from HiSilicon.
+ *
+ * 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
+ * UART2. This is only for the informational lines i.e. "[FOO]",
+ * the GPIO named lines "GPIO-A" thru "GPIO-L" are the only
