59 * Legend: proper name = the GPIO line is used as GPIO
60 *         NC = not connected (pin out but not routed from the chip to
61 *              anything the board)
62 *         "[PER]" = pin is muxed for [peripheral] (not GPIO)
63 *         "" = no idea, schematic doesn't say, could be
64 *              unrouted (not connected to any external pin)
65 *         LSEC = Low Speed External Connector
66 *         HSEC = High Speed External Connector
67 *
68 * Line names are taken from "hikey970-schematics.pdf" from HiSilicon.
69 *
70 * For the lines routed to the external connectors the
71 * lines are named after the 96Boards CE Specification 1.0,
72 * Appendix "Expansion Connector Signal Description".
73 *
74 * When the 96Board naming of a line and the schematic name of
75 * the same line are in conflict, the 96Board specification
76 * takes precedence, which means that the external UART on the
77 * LSEC is named UART0 while the schematic and SoC names this
78 * UART2. This is only for the informational lines i.e. "[FOO]",
79 * the GPIO named lines "GPIO-A" thru "GPIO-L" are the only
80 * ones actually used for GPIO.
