/*
 * 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
 *         P HSEC  = Primary High Speed External Connector
 *         S HSEC  = Secondary High Speed External Connector
 *         J14     = Camera Connector
 *         TP      = Test Points
 *
 * Line names are taken from the schematic "DragonBoard 820c",
 * drawing no: LM25-P2751-1
 *
 * 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.
