Ok, I was already wondering if this would be the right way.


With the feedback I have so far, I think we have

drivers/char/tty_*      -> tty/*
drivers/char/{vt stuff} -> tty/vt/
drivers/char/hvc_*      -> drivers/tty/hvc/hvc_*
drivers/serial/*        -> drivers/tty/serial/*
drivers/usb/serial      -> drivers/usb/serial

cyclades,moxa,mxser     -> drivers/tty/hw/

stallion,istallion,
epca,specialix,ip2,
riscom,isicom           -> drivers/staging/tty/*

generic_serial,vme_scc,
ser_a2232,sx,rio        -> drivers/staging/generic_serial/*

amiserial,nozomi,
serial167,synclink      -> drivers/tty/hw (?)

bfin_jtag_comm          -> drivers/tty/hvc/hvc_bfin_jtag (?)

rocket,ipwireless       -> drivers/staging/tty/* (?)

I'll wait a few days for other suggestions and then prepare
a new patch series.
