Freescale high-speed USB SOC can be found on some Freescale processors
among different architectures. It supports both host and device functions.
This driver adds its device support for Linux USB Gadget layer.
It is tested on MPC8349 and MPC8313, but should work on other platforms
with minor tweaks. The driver passed USBCV 1.3 compliance tests. Note
that this driver doesn't yet include OTG support.

The driver uses usb_control_msg() for exchanging data with the device.
When the driver lived freeley _outside_ the kernel tree (pre 2.6.21) the
timeouts for these calls where set to 5*HZ for reading, 1HZ for writing.
(These timeouts seemed to work fine for all users of the driver, at
least nobody complained in the last 2 years.
The current code (2.6.21-rc5) removed the 'HZ' from the timeouts and
left the driver with 5 jiffies for reading and 1 jiffy for writing. My
new machine is fast, but not that fast.
The patch also removes a useless debug statement, which was left over
from testing a broken firmware version

Per the Rui Santos and the hardware manufacturers, this actually inhibits
useful parts of the hardware. The correct way to use this hardware is with the
software at http://www.kanoistika.sk/bobovsky/archiv/umts/ and the manufacturers
are also planning on including Linux drivers/material in future revisions.

The device has commands to start/stop the ADSL function, so this adds a
sysfs attribute to allow it to be started/stopped/restarted. It also stops
polling the device for status when the ADSL function is disabled.
There are no problems with sending multiple start or stop commands, even
with a fast loop of them the device still works. There is no need to
protect the restart process from further user actions while it's waiting
for 1.5s.

Add the "bus zero" feature to the usbmon. If a user process specifies bus
with number zero, it receives events from all buses. This is useful when
we wish to see initial enumeration when a bus is created, typically after
a modprobe. Until now, an application had to loop until a new bus could
be open, then start capturing on it. This procedure was cumbersome and
could lose initial events. Also, often it's too bothersome to find exactly
to which bus a specific device is attached.
Paolo Albeni provided the original concept implementation. I added the
handling of "bus->monitored" flag and generally fixed it up.

This patch (as877) adds a "last_busy" field to struct usb_device, for
use by the autosuspend framework. Now if an autosuspend call comes at
a time when the device isn't busy but hasn't yet been idle for long
enough, the timer can be set to exactly the desired value. And we
will be ready to handle things like HID drivers, which can't maintain
a useful usage count and must rely on the time-of-last-use to decide
when to autosuspend.
The patch also makes some related minor improvements:
Move the calls to the autosuspend condition-checking routine
into usb_suspend_both(), which is the only place where it
really matters.
If the autosuspend timer is already running, don't stop
and restart it.
Replace immediate returns with gotos so that the optional
debugging ouput won't be bypassed.
If autoresume is disabled but the device is already awake,
don't return an error for an autoresume call.
Don't try to autoresume a device if it isn't suspended.
(Yes, this undercuts the previous change -- so sue me.)
Don't duplicate existing code in the autosuspend work routine.
Fix the kerneldoc in usb_autopm_put_interface(): If an
autoresume call fails, the usage counter is left unchanged.

o The "real" usb-devices export now a device node which can
populate /dev/bus/usb.
o The usb_device class is optional now and can be disabled in the
kernel config. Major/minor of the "real" devices and class devices
are the same.
o The environment of the usb-device event contains DEVNUM and BUSNUM to
help udev and get rid of the ugly udev rule we need for the class
devices.
o The usb-devices and usb-interfaces share the same bus, so I used
the new "struct device_type" to let these devices identify
themselves. This also removes the current logic of using a magic
platform-pointer.
The name of the device_type is also added to the environment
which makes it easier to distinguish the different kinds of devices
on the same subsystem.
It looks like this:
add@/devices/pci0000:00/0000:00:1d.1/usb2/2-1
ACTION=add
DEVPATH=/devices/pci0000:00/0000:00:1d.1/usb2/2-1
SUBSYSTEM=usb
SEQNUM=1533
MAJOR=189
MINOR=131
DEVTYPE=usb_device
PRODUCT=46d/c03e/2000
TYPE=0/0/0
BUSNUM=002
DEVNUM=004
This udev rule works as a replacement for usb_device class devices:
SUBSYSTEM=="usb", ACTION=="add", ENV{DEVTYPE}=="usb_device", \
NAME="bus/usb/$env{BUSNUM}/$env{DEVNUM}", MODE="0644"
Updated patch, which needs the device_type patches in Greg's tree.
