68 * GPIO name legend: proper name = the GPIO line is used as GPIO
69 * NC = not connected (pin out but not routed from the chip to
70 * anything the board)
71 * "[PER]" = pin is muxed for [peripheral] (not GPIO)
72 * LSEC = Low Speed External Connector
73 * HSEC = High Speed External Connector
74 *
75 * Line names are taken from the schematic "Schematics Bubblegum96"
76 * version v1.0
77 *
78 * For the lines routed to the external connectors the
79 * lines are named after the 96Boards CE Specification 1.0,
80 * Appendix "Expansion Connector Signal Description".
81 *
82 * When the 96Boards naming of a line and the schematic name of
83 * the same line are in conflict, the 96Boards specification
84 * takes precedence, which means that the external UART on the
85 * LSEC is named UART0 while the schematic and SoC names this
86 * UART2. Only exception is the I2C lines for which the schematic
87 * naming has been preferred. This is only for the informational
88 * lines i.e. "[FOO]", the GPIO named lines "GPIO-A" thru "GPIO-L"
89 * are the only ones actually used for GPIO.
