70 * Legend: proper name = the GPIO line is used as GPIO
71 * NC = not connected (not routed from the SoC)
72 * "[PER]" = pin is muxed for peripheral (not GPIO)
73 * "" = no idea, schematic doesn't say, could be
74 * unrouted (not connected to any external pin)
75 * LSEC = Low Speed External Connector
76 * HSEC = High Speed External Connector
78 * Pin assignments taken from LeMaker and CircuitCo Schematics
81 * For the lines routed to the external connectors the
82 * lines are named after the 96Boards CE Specification 1.0,
83 * Appendix "Expansion Connector Signal Description".
85 * When the 96Board naming of a line and the schematic name of
86 * the same line are in conflict, the 96Board specification
87 * takes precedence, which means that the external UART on the
88 * LSEC is named UART0 while the schematic and SoC names this
89 * UART2. This is only for the informational lines i.e. "[FOO]",
90 * the GPIO named lines "GPIO-A" thru "GPIO-L" are the only
91 * ones actually used for GPIO.
