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.

Add force-feedback support for N64 pads with rumble pak accessory installed.
Actually we do not check for the presence of rumble pad but simply assume it
is installed and expect the device to ignore FF commands if rumble pak is
missing.

This is a driver for Zhen Hua PPM-4CH RC transmitter (commonly used in cheap
Ready To Fly RC helicopters by Walkera) which using "Zhen Hua 5-byte protocol"
for using them as a four axis joystick via serial port. Transmitter connected
to serial port (19200 8N1) sending periodically 5 bytes where first byte is for
synchronization and next four bytes are values of axis.

Export LEDs on Xbox360 pad via led subsystem as a single device in
/sys/class/leds/xpad[0-9]+.
Xbox360 pad has four leds, which form a circle. Unfortunately the leds
can't be controlled independently and can only display a predefined
set of patterns (for example one is turned on wile others are off or
a rotating pattern - 1-2-3-4). To activate a pattern one needs to send
a specific command to the device (see http://www.free60.org/wiki/Gamepad).
Led subsystem allows us to set brightness, but there is nothing like
brightness on this device. So brightness is actually interpreted as
the command (only values between 0 and 14 are accepted).

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
