+ * 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 "Schematics Bubblegum96"
+ * version v1.0
+ *
+ * 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 96Boards naming of a line and the schematic name of
+ * the same line are in conflict, the 96Boards specification
+ * takes precedence, which means that the external UART on the
+ * LSEC is named UART0 while the schematic and SoC names this
+ * UART2. Only exception is the I2C lines for which the schematic
+ * naming has been preferred. 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.
