[linux-vr-cvsupdate] Update to module linux

[Michael K. <mf...@us...>]

Update of /cvsroot/linux-vr/linux/arch/mips/vr41xx
In directory slayer.i.sourceforge.net:/tmp/cvs-serv22424/arch/mips/vr41xx

Modified Files:
	serial.c 
Log Message:
Clean up the VR41xx UART port IO handling a little, in preparation for
merge back into drivers/char/serial.c, also to support multiple UARTs on
VR4181.

First stab at SIR IrDA support.  IrDA mode of the UART can be accessed
via /dev/ttyS1.  Still pretty hackish at this point, as there is no
interlock between the non-IrDA mode tty and the IrDA mode tty, I'll get
on that soon, but it should be usable if one is careful not to open
/dev/ttyS0 and /dev/ttyS1 at the same time (for non-VR4181).  I have no
idea if this works, probably not unless the IrDA tranceiver happens to
already be powered on...

Added serial power on/off defs for Freestyle (I think these are right...)
