usb: musb: do not use dma for control transfers

2010-11-22T10:55:02+00:00

The Inventra DMA engine used with the MUSB controller in many
SoCs cannot use DMA for control transfers on EP0, but can use
DMA for all other transfers.

The USB core maps urbs for DMA if hcd->self.uses_dma is true.
(hcd->self.uses_dma is true for MUSB as well).

Split the uses_dma flag into two - one that says if the
controller needs to use PIO for control transfers, and
another which says if the controller uses DMA (for all
other transfers).

Also, populate this flag for all MUSB by default.

(Tested on OMAP3 and OMAP4 boards, with EHCI and MUSB HCDs
simultaneously in use).

USB: use the runtime-PM autosuspend implementation

2010-11-16T22:03:41+00:00

This patch (as1428) converts USB over to the new runtime-PM core
autosuspend framework.  One slightly awkward aspect of the conversion
is that USB devices will now have two suspend-delay attributes: the
old power/autosuspend file and the new power/autosuspend_delay_ms
file.  One expresses the delay time in seconds and the other in
milliseconds, but otherwise they do the same thing.  The old attribute
can be deprecated and then removed eventually.

USB: make usb_mark_last_busy use pm_runtime_mark_last_busy

2010-11-16T22:02:54+00:00

Since the runtime-PM core already defines a .last_busy field in
device.power, this patch uses it to replace the .last_busy field
defined in usb_device and uses pm_runtime_mark_last_busy to implement
usb_mark_last_busy.

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
