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
50 * "[PER]" = pin is muxed for [peripheral] (not GPIO)
51 * LSEC = Low Speed External Connector
52 * HSEC = High Speed External Connector
54 * Line names are taken from the schematic "Schematics Bubblegum96"
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".
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.
