ModemManager likes to play with serial ports it shouldn't
play with, mark our serial ports as off limits.
This also bumps the ordering of this rules file just past
the udev default rules because it uses environment variables
populated by that file.

TEST=install new rules file, delete old rules file
verify that symlinks to TTY's are still created
verify that ModemManager leaves them alone now

This udev rule creates a directory in /dev/google for each
device attached. The name of the directory is unique to the
device and is prefixed with the device product name. Within
the directory there is a serial directory that contains
symlinks to each USB serial port exposed by the device. The
symlinks are named based on the USB interface name provided
by the EC. Additional subdirectories can be added for I2C,
JTAG, GPIOs, and SPI as needed.

This is a simple kernel module and Makefile for
building it out of tree. This module just uses
the existing kernel usb serial driver and probes
for the Google VID/Class/SubClass/Protocol that
identifies a valid simple serial interface.
This code should be rolled into the existing kernel
driver at: drivers/usb/serial/usb-serial-simple.c
While that happens, this module is still useful to
developers.
