usb: musb: pass configuration specifics via pdata

2008-08-14T00:33:01+00:00

Use platform_data to pass musb configuration-specific
details to musb driver.

This patch will prevent that other platforms selecting
HAVE_CLK and enabling musb won't break tree building.

The other parts of it will come when linux-omap merge
up more omap2/3 board-files.

usb: musb: fix hanging when rmmod gadget driver

2008-08-14T00:33:00+00:00

If we try to modprobe a second gadget driver before
rmmoding the first one, the reference for the first
gadget driver would get NULLed avoiding usb to change
gadget drivers later.

USB: Add MUSB and TUSB support

2008-08-14T00:33:00+00:00

This patch adds support for MUSB and TUSB controllers
integrated into omap2430 and davinci. It also adds support
for external tusb6010 controller.

USB: serial: remove CONFIG_USB_DEBUG from sierra and option drivers

2008-08-14T00:33:00+00:00

These drivers should not be relying on CONFIG_USB_DEBUG.  By doing this,
it prevents users of kernels that do not enable this option from
enabling debugging in these drivers, unlike all other usb-serial
drivers.

USB: Add vendor/product id of ZTE MF628 to option

2008-08-14T00:32:58+00:00

This adds the vendor and product id (19d2:0015) of the ZTE MF628 HSDPA
modem to the option driver. It still needs a mode switch command issued
beforehand, this is currently handled by a userspace tool.

USB: quirk PLL power down mode

2008-08-14T00:32:58+00:00

On some AMD 700 series southbridges, ISO OUT transfers (such as audio
playback through speakers) on the USB OHCI controller may be corrupted
when an A-Link express power saving feature is active.

PLL power down mode in conjunction with link power management feature
L1 being enabled is the bad combination ... this patch prevents them
from being enabled when ISO transfers are pending.

usb: cdc-acm: drain writes on close

2008-08-14T00:32:57+00:00

Add a mechanism to let the write queue drain naturally before
closing the TTY, rather than always losing that data.  There
is a timeout, so it can't wait too long.

Provide missing locking inside acm_wb_is_avail(); it matters
more now.  Note, this presumes an earlier patch was applied,
removing a call to this routine where the lock was held.

Slightly improved diagnostics on write URB completion, so we
can tell when a write URB gets killed and, if so, how much
data it wrote first ... and so that I/O path is normally
silent (and can't much change timings).

usb: cdc-acm: stop dropping tx buffers

2008-08-14T00:32:57+00:00

The "increase cdc-acm write throughput" patch left in place two
now-obsolete mechanisms, either of which can make the cdc-acm
driver drop TX data (nasty!).  This patch removes them:

  - The write_ready flag ... if an URB and buffer were found,
    they can (and should!) always be used.

  - TX path acm_wb_is_used() ... used when the buffer was just
    allocated, so that check is pointless.

Also fix a won't-yet-matter leak of a write buffer on a disconnect path.
