68 depends on SIBYTE_SB1xxx_SOC=y
72 Support for the asynchronous serial interface (DUART) included in
73 the BCM1250 and derived System-On-a-Chip (SOC) devices. Note that
74 the letter D in DUART stands for "dual", which is how the device
75 is implemented. Depending on the SOC configuration there may be
76 one or more DUARTs available of which all are handled.

119 actually use DMA transfers, make sure that the use_dma_tx
120 and use_dma_rx members in the atmel_uart_data struct is set
121 appropriately for each port.

131 Say Y here if you wish to have the internal AT91 / AT32 UARTs
132 appear as /dev/ttyATn (major 204, minor starting at 154)
133 instead of the normal /dev/ttySn (major 4, minor starting at
134 64). This is necessary if you also want other UARTs, such as
135 external 8250/16C550 compatible UARTs.
136 The ttySn nodes are legally reserved for the 8250 serial driver
137 but are often misused by other serial drivers.
139 To use this, you should create suitable ttyATn device nodes in
140 /dev/, and pass "console=ttyATn" to the kernel.

763 The pmac_zilog driver for the z85C30 chip on many powermacs
764 historically used the device numbers for /dev/ttySn. The
765 8250 serial port driver also uses these numbers, which means
766 the two drivers being unable to coexist; you could not use
767 both z85C30 and 8250 type ports at the same time.
769 If this option is not selected, the pmac_zilog driver will
770 use the device numbers allocated for /dev/ttyPZn. This allows
771 the pmac_zilog and 8250 drivers to co-exist, but may cause
772 existing userspace setups to break. Programs that need to
773 access the built-in serial ports on powermacs will need to
774 be reconfigured to use /dev/ttyPZn instead of /dev/ttySn.
776 If you enable this option, any z85c30 ports in the system will
777 be registered as ttyS0 onwards as in the past, and you will be
778 unable to use the 8250 module for PCMCIA or other 16C550-style
