fdf290fd6d [PATCH] UEAGLE : cmv name bug (was cosmetic)
this patch correct a possible bug with cmv_name being static. If there
is 2 modems and the driver is scheduled when filling cmv_name this could
result with garbage in cmv_name. We allocate cmv_name on the stack but
with a small size in order to avoid that.

3c9666cc18 [PATCH] UEAGLE : add iso support
This patch adds the support for isochronous pipe.

A new module parameter is added to select iso mode.  It is set to iso by
default because bulk mode doesn't work well at high speed rate (>3 Mbps
for upload).

We use UDSL_IGNORE_EILSEQ flags because ADI firmware doesn't reply to
ISO IN when it has nothing to send [1].

[1]
from cypress datasheet :

The ISOSEND0 Bit (bit 7 in the USBPAIR Register) is used when the EZ-USB
FX chip receives an isochronous IN token while the IN FIFO is empty. If
ISOSEND0=0 (the default value), the USB core does not respond to the IN
token. If ISOSEND0=1, the USB core sends a zero-length data packet in
response to the IN token. The action to take depends on the overall
system design. The ISOSEND0 Bit applies to all of the isochronous IN
endpoints, IN-8 through IN-15.

80aae7a17a [PATCH] USBATM: allow isochronous transfer
While the usbatm core has had some support for using isoc urbs
for some time, there was no way for users to turn it on.  While
use of isoc transfer should still be considered experimental, it
now works well enough to let users turn it on.  Minidrivers signal
to the core that they want to use isoc transfer by setting the new
UDSL_USE_ISOC flag.  The speedtch minidriver gets a new module
parameter enable_isoc (defaults to false), plus some logic that
checks for the existence of an isoc receive endpoint (not all
speedtouch modems have one).

35644b0cce [PATCH] USBATM: add flags field
Have minidrivers and the core signal special requirements
using a flags field in struct usbatm_data.  For the moment
this is only used to replace the need_heavy_init bind
parameter, but there'll be new flags in later patches.

b72458a80c [PATCH] USB: Eagle and ADI 930 usb adsl modem driver
A driver for USB ADSL modems based on the ADI eagle chipset using the
usb_atm infrastructure.

The managing part was taken from bsd ueagle driver, other parts were
written from scratch.

The driver uses the in-kernel firmware loader :
- to load  a first usb firmware when the modem is in pre-firmware state
- to load the dsp firmware that are swapped in host memory.
- to load CMV (configuration and management variables) when the modem
boot. (We can't use options or sysfs for this as there many possible
values. See
https://mail.gna.org/public/eagleusb-dev/2005-04/msg00031.html for a
description of some)
- to load fpga code for 930 chipset.

The device had 4 endpoints :
* 2 for data (use by usbatm). The incoming
endpoint could be iso or bulk. The modem seems buggy and produce lot's
of atm errors when using it in bulk mode for speed > 3Mbps, so iso
endpoint is need for speed > 3Mbps. At the moment iso endpoint need a
patched usbatm library and for this reason is not included in this patch.

* One bulk endpoint for uploading dsp firmware

* One irq endpoint that notices the driver
    - if we need to upload a page of the dsp firmware
    - an ack for read or write CMV and the value (for the read case).

If order to make the driver cleaner, we design synchronous
(read|write)_cmv :
-send a synchronous control message to the modem
-wait for an ack or a timeout
-return the value if needed.

In order to run these synchronous usb messages we need a kernel thread.

The driver has been tested  with sagem fast 800 modems with different
eagle chipset revision and with ADI 930 since April 2005.
