0068 * GPIO name legend: proper name = the GPIO line is used as GPIO
0069 * NC = not connected (pin out but not routed from the chip to
0070 * anything the board)
0071 * "[PER]" = pin is muxed for [peripheral] (not GPIO)
0072 * LSEC = Low Speed External Connector
0073 * HSEC = High Speed External Connector
0074 *
0075 * Line names are taken from the schematic "Schematics Bubblegum96"
0076 * version v1.0
0077 *
0078 * For the lines routed to the external connectors the
0079 * lines are named after the 96Boards CE Specification 1.0,
0080 * Appendix "Expansion Connector Signal Description".
0081 *
0082 * When the 96Boards naming of a line and the schematic name of
0083 * the same line are in conflict, the 96Boards specification
0084 * takes precedence, which means that the external UART on the
0085 * LSEC is named UART0 while the schematic and SoC names this
0086 * UART2. Only exception is the I2C lines for which the schematic
0087 * naming has been preferred. This is only for the informational
0088 * lines i.e. "[FOO]", the GPIO named lines "GPIO-A" thru "GPIO-L"
0089 * are the only ones actually used for GPIO.
