	  Say Y here if you wish to use the PDC to do DMA transfers to
	  and from the Atmel AT91 / AT32 serial port. In order to
	  actually use DMA transfers, make sure that the use_dma_tx
	  and use_dma_rx members in the atmel_uart_data struct is set
	  appropriately for each port.

	  Note that break and error handling currently doesn't work
	  properly when DMA is enabled. Make sure that ports where

config SERIAL_ATMEL_TTYAT

	  Say Y here if you wish to have the internal AT91 / AT32 UARTs
	  appear as /dev/ttyATn (major 204, minor starting at 154)
	  instead of the normal /dev/ttySn (major 4, minor starting at
	  64). This is necessary if you also want other UARTs, such as
	  external 8250/16C550 compatible UARTs.
	  The ttySn nodes are legally reserved for the 8250 serial driver
	  but are often misused by other serial drivers.

	  To use this, you should create suitable ttyATn device nodes in
	  /dev/, and pass "console=ttyATn" to the kernel.

	  Say Y if you have an external 8250/16C550 UART.  If unsure, say N.

config SERIAL_KGDB_NMI
	bool "Serial console over KGDB NMI debugger port"
	depends on KGDB_SERIAL_CONSOLE
	help
	  This special driver allows you to temporary use NMI debugger port
	  as a normal console (assuming that the port is attached to KGDB).

	  Unlike KDB's disable_nmi command, with this driver you are always
	  able to go back to the debugger using KGDB escape sequence ($3#33).
	  This is because this console driver processes the input in NMI
	  context, and thus is able to intercept the magic sequence.

	  Note that since the console interprets input and uses polling
	  communication methods, for things like PPP you still must fully
	  detach debugger port from the KGDB NMI (i.e. disable_nmi), and
	  use raw console.

	  If unsure, say N.

config SERIAL_KS8695
