This patch removes the depends on USB from all config symbols in
drivers/usb/host/Kconfig and replace that with an if USB / endif block
as suggested by Alan Stern. Some source ... Kconfig lines have been
shuffled around to permit a better regroupment of the Kconfig files
depending on "config USB" item. No functionnal change is introduced.

The option allows you to remove TTY and compile without errors. This
saves space on systems that won't support TTY interfaces anyway.
bloat-o-meter output is below.

The bulk of this patch consists of Kconfig changes adding "depends on
TTY" to various serial devices and similar drivers that require the TTY
layer.  Ideally, these dependencies would occur on a common intermediate
symbol such as SERIO, but most drivers "select SERIO" rather than
"depends on SERIO", and "select" does not respect dependencies.

bloat-o-meter output comparing our previous minimal to new minimal by
removing TTY.  The list is filtered to not show removed entries with awk
'$3 != "-"' as the list was very long.

It's out-dated for the tty-layer stuff, and would require a bunch of
work.  That's not really a big deal, the big issue is that there is no
company contact for the hardware, so questions we have about it (like
why isn't this just handled by the cdc-acm driver instead?) go
unanswered.

So drop the driver.  If someone comes along to help answer the
questions, we can easily revert this and fix up the code.

Here's a driver for the Vizzini USB to serial device.
It looks to be copied from cdc-acm, and probably can be cleaned up a lot
more.  Also, there's some odd "try to grab another interface" that is
probably wrong.  And, if this really is a cdc-acm device, it probably
should just be a quirk of the cdc-acm device, but I can't figure that
out, and people have been using this driver for a long time now.  So
merge it to let people use their hardware and clean it up over time.

Driver written by Rob Duncan but cleaned up and forward ported to the
latest kernel tree by me.

This adds a driver for the zte_ev set of usb to serial devices.  It is
based on a patch floating around the internet that modified the generic
usb-serial driver to only work for this type of device.

I've left comments in the code that I think show the data commands being
sent to the device, which I'm guessing come from a usb analyzer.  Maybe
they can help others out as well.

Many thanks to nirinA raseliarison for pointing the original patch out
to me, and for testing that the driver works properly.

This reverts commit 90593899.

SAM-BA devices identify themselves CDC-ACM devices and should be using
the cdc-acm driver.

Since commit 5b239f0a (USB: cdc-acm: Add pseudo
modem without AT command capabilities) cdc-acm also binds to them.

Note that the Atmel SAM-BA tools expect to use a USB-serial driver and thus
require a symlink from /dev/ttyACMn to some /dev/ttyUSBm (with m < 30) to be
able to select the device. This is simply a UI-issue that should be
fixed by Atmel.

Tested with the SAM-BA 2.10 tools and an Atmel at91sam9260-ek.

Add support for the parallel port on the moschip MCS7715 device.  The port
registers itself with the parport subsystem as a low-level driver.  A separate
entry to the kernel configuration is added beneath that for the mos7720, to
avoid the need to link with the parport subsystem code for users who don't have
or don't want the parallel port.  Only compatibility mode is currently supported
(no ECP/EPP).  Tested with both moschip devices (7720 and 7715) on UP and SMP
hosts, including regression testing of serial port, concurrent operation of
serial and parallel ports, and various connect / disconnect scenarios.
