* 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.
