Revert "USB: Adding support for HTC Smartphones to ipaq"

2010-08-10T21:35:35+00:00

ipaq already had this device id defined:

{ USB_DEVICE(0x0BB4, 0x00CF) }, /* HTC USB Modem */

Revert the commit which adds the duplicate entry.

This reverts commit 04cab1329336d4577d6638360c905e360934b425.

USB: ipaq: reimplement using generic framework

2010-05-20T20:21:48+00:00

Kill custom fifo, read and write implementations (single-urb and fifo,
but still maintained list of 256*256b urb buffers per port).

Compile-only tested.

USB: serial: allow drivers to define bulk buffer sizes

2010-05-20T20:21:33+00:00

Allow drivers to define custom bulk in/out buffer sizes in struct
usb_serial_driver. If not set, fall back to the default buffer size
which matches the endpoint size.

Three drivers are currently freeing the pre-allocated buffers and
allocating larger ones to achieve this at port probe (ftdi_sio) or even
at port open (ipaq and iuu_phoenix), which needless to say is suboptimal.

USB: tty: Prune uses of tty_request_room in the USB layer

2010-03-02T22:55:12+00:00

We have lots of callers that do not need to do this in the first place.
Remove the calls as they both cost CPU and for big buffers can mess up the
multi-page allocation avoidance.

USB: ipaq: fix oops when device is plugged in

2009-10-09T20:52:07+00:00

This patch (as1293) fixes a problem with the ipaq serial driver.  It
tries to bind to all the interfaces, even those that don't have enough
endpoints.  The symptom is an invalid memory reference and oops when
the device is plugged in.

tty: USB does not need the filp argument in the drivers

2009-09-19T20:13:26+00:00

And indeed none of them use it. Clean this up as it will make moving to a
standard open method rather easier.

USB: usb-serial: replace shutdown with disconnect, release

2009-06-16T04:44:47+00:00

This patch (as1254) splits up the shutdown method of usb_serial_driver
into a disconnect and a release method.

The problem is that the usb-serial core was calling shutdown during
disconnect handling, but drivers didn't expect it to be called until
after all the open file references had been closed.  The result was an
oops when the close method tried to use memory that had been
deallocated by shutdown.

tty: Bring the usb tty port structure into more use

2009-06-11T15:50:56+00:00

This allows us to clean stuff up, but is probably also going to cause
some app breakage with buggy apps as we now implement proper POSIX behaviour
for USB ports matching all the other ports. This does also mean other apps
that break on USB will now work properly.

USB: removal of tty->low_latency hack dating back to the old serial code

2009-04-23T21:15:29+00:00

This removes tty->low_latency from all USB serial drivers that push
data into the tty layer at hard interrupt context. It's no longer needed
and actually harmful.

USB: ipaq: handle 4 endpoint devices

2009-03-24T23:20:45+00:00

The ipaq driver currently enforces one port on all devices. This
is correct for 2 and 3 endpoint devices, but with 4 endpoint devices
meaningful communication occurs on the second pair.

This patch allows 2 ports for 4 endpoint devices.
