+ * GPIO name 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)
+ *         LSEC = Low Speed External Connector
+ *         HSEC = High Speed External Connector
+ *
+ * Line names are taken from the schematic "sophon-edge-schematics"
+ * version, 1.0210.
+ *
+ * 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. 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.
