/*
 * GPIO name legend: proper name = the GPIO line is used as GPIO
 *         NC = not connected (pin out but not routed from the chip to
 *              anything the board)
 *         "[PER]" = pin is muxed for [peripheral] (not GPIO)
 *         LSEC = Low Speed External Connector
 *         HSEC = High Speed External Connector
 *
 * Line names are taken from the schematic "DragonBoard410c"
 * dated monday, august 31, 2015. Page 5 in particular.
 *
 * For the lines routed to the external connectors the
 * lines are named after the 96Boards CE Specification 1.0,
 * Appendix "Expansion Connector Signal Description".
 *
 * When the 96Board naming of a line and the schematic name of
 * the same line are in conflict, the 96Board specification
 * takes precedence, which means that the external UART on the
 * LSEC is named UART0 while the schematic and SoC names this
 * UART3. This is only for the informational lines i.e. "[FOO]",
 * the GPIO named lines "GPIO-A" thru "GPIO-L" are the only
 * ones actually used for GPIO.
