* 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
|
|
* HSEC = High Speed External Connector
|
|
*
|
|
* Line names are taken from the schematic "sophon-edge-schematics"
|
|
* version, 1.0210.
|
|
*
|
|
* 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. 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.
