47 * GPIO name legend: proper name = the GPIO line is used as GPIO
48 *         NC = not connected (pin out but not routed from the chip to
49 *              anything the board)
50 *         "[PER]" = pin is muxed for [peripheral] (not GPIO)
51 *         LSEC = Low Speed External Connector
52 *         HSEC = High Speed External Connector
53 *
54 * Line names are taken from the schematic "Schematics Bubblegum96"
55 * version v1.0
56 *
57 * For the lines routed to the external connectors the
58 * lines are named after the 96Boards CE Specification 1.0,
59 * Appendix "Expansion Connector Signal Description".
60 *
61 * When the 96Boards naming of a line and the schematic name of
62 * the same line are in conflict, the 96Boards specification
63 * takes precedence, which means that the external UART on the
64 * LSEC is named UART0 while the schematic and SoC names this
65 * UART2. Only exception is the I2C lines for which the schematic
66 * naming has been preferred. This is only for the informational
67 * lines i.e. "[FOO]", the GPIO named lines "GPIO-A" thru "GPIO-L"
68 * are the only ones actually used for GPIO.
