112 * Legend: proper name = the GPIO line is used as GPIO
113 * NC = not connected (not routed from the SoC)
114 * "[PER]" = pin is muxed for peripheral (not GPIO)
115 * "" = no idea, schematic doesn't say, could be
116 * unrouted (not connected to any external pin)
117 * LSEC = Low Speed External Connector
118 * HSEC = High Speed External Connector
120 * Pin assignments taken from LeMaker and CircuitCo Schematics
123 * For the lines routed to the external connectors the
124 * lines are named after the 96Boards CE Specification 1.0,
125 * Appendix "Expansion Connector Signal Description".
127 * When the 96Board naming of a line and the schematic name of
128 * the same line are in conflict, the 96Board specification
129 * takes precedence, which means that the external UART on the
130 * LSEC is named UART0 while the schematic and SoC names this
131 * UART2. This is only for the informational lines i.e. "[FOO]",
132 * the GPIO named lines "GPIO-A" thru "GPIO-L" are the only
133 * ones actually used for GPIO.
