203 * Legend: proper name = the GPIO line is used as GPIO
204 *         NC = not connected (pin out but not routed from the chip to
205 *              anything the board)
206 *         "[PER]" = pin is muxed for [peripheral] (not GPIO)
207 *         "" = no idea, schematic doesn't say, could be
208 *              unrouted (not connected to any external pin)
209 *         LSEC = Low Speed External Connector
210 *         HSEC = High Speed External Connector
211 *
212 * Line names are taken from "HiKey 960 Board ver A" schematics
213 * from Huawei. The 40 pin low speed expansion connector is named
214 * J2002 63453-140LF.
215 *
216 * For the lines routed to the external connectors the
217 * lines are named after the 96Boards CE Specification 1.0,
218 * Appendix "Expansion Connector Signal Description".
219 *
220 * When the 96Board naming of a line and the schematic name of
221 * the same line are in conflict, the 96Board specification
222 * takes precedence, which means that the external UART on the
223 * LSEC is named UART0 while the schematic and SoC names this
224 * UART3. This is only for the informational lines i.e. "[FOO]",
225 * the GPIO named lines "GPIO-A" thru "GPIO-L" are the only
226 * ones actually used for GPIO.
