0019 * GPIO name legend: proper name = the GPIO line is used as GPIO
0020 * NC = not connected (pin out but not routed from the chip to
0021 * anything the board)
0022 * "[PER]" = pin is muxed for [peripheral] (not GPIO)
0023 * LSEC = Low Speed External Connector

0025 * S HSEC = Secondary High Speed External Connector
0026 * J14 = Camera Connector
0027 * TP = Test Points
0028 *
0029 * Line names are taken from the schematic "DragonBoard 820c",
0030 * drawing no: LM25-P2751-1
0031 *
0032 * For the lines routed to the external connectors the
0033 * lines are named after the 96Boards CE Specification 1.0,
0034 * Appendix "Expansion Connector Signal Description".
0035 *
0036 * When the 96Board naming of a line and the schematic name of
0037 * the same line are in conflict, the 96Board specification
0038 * takes precedence, which means that the external UART on the
0039 * LSEC is named UART0 while the schematic and SoC names this
0040 * UART3. This is only for the informational lines i.e. "[FOO]",
0041 * the GPIO named lines "GPIO-A" thru "GPIO-L" are the only
0042 * ones actually used for GPIO.
