/*
* 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.
