75

76

77

78
+ * For the lines routed to the external connectors the
79
+ * lines are named after the 96Boards CE Specification 1.0,
80
+ * Appendix "Expansion Connector Signal Description".
81
+ *
82
+ * When the 96Boards naming of a line and the schematic name of
83
+ * the same line are in conflict, the 96Boards specification
84
+ * takes precedence, which means that the external UART on the
85
+ * LSEC is named UART0 while the schematic and SoC names this
86
+ * UART2. Only exception is the I2C lines for which the schematic
87
+ * naming has been preferred. This is only for the informational
88
+ * lines i.e. "[FOO]", the GPIO named lines "GPIO-A" thru "GPIO-L"
89
+ * are the only ones actually used for GPIO.
