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.
