USB: ehci: tegra: Align DMA transfers to 32 bytes

2010-12-17T19:51:52+00:00

The Tegra2 USB controller doesn't properly deal with misaligned DMA
buffers, causing corruption.  This is especially prevalent with USB
network adapters, where skbuff alignment is often in the middle of a
4-byte dword.

To avoid this, allocate a temporary buffer for the DMA if the provided
buffer isn't sufficiently aligned.

USB-BKL: Convert usb_driver ioctl to unlocked_ioctl

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

And audit all the users. None needed the BKL.  That was easy
because there was only very few around.

Tested with allmodconfig build on x86-64

Now that all callers are converted over, remove the compatibility
functions and all is good.

USB: remove usb_find_device

2010-05-20T20:21:45+00:00

Now on one uses this function and it seems useless,
so remove usb_find_device.

USB: simplify usb_sg_init()

2010-05-20T20:21:42+00:00

This patch (as1377) simplifies the code in usb_sg_init(), without
changing its functionality.  It also removes a couple of unused fields
from the usb_sg_request structure.

USB: Change the scatterlist type in struct urb

2010-05-20T20:21:41+00:00

Change the type of the URB's 'sg' pointer from a usb_sg_request to
a scatterlist.  This allows drivers to submit scatter-gather lists
without using the usb_sg_wait() interface.  It has the added benefit
of removing the typecasts that were added as part of patch as1368 (and
slightly decreasing the number of pointer dereferences).

USB: Add a usb_pipe_endpoint() convenience function

2010-05-20T20:21:41+00:00

Converting a pipe number to a struct usb_host_endpoint pointer is a little
messy.  Introduce a new convenience function to hide the mess.
