Randy Dunlap reported this error when compiling the xHCI driver:
linux-next-20100104/drivers/usb/host/xhci.h:1214:
sorry, unimplemented: inlining failed in call to 'xhci_get_slot_state': function body not available
The xhci_get_slot_state() function belongs in xhci-dbg.c, since it
involves debugging internal xHCI structures. However, it is only used in
xhci-hcd.c. Some toolchains may have issues since the inlined function
body is not in the xhci.h header file. Remove the inline keyword to avoid
this.

The original code was passing a stack variable as a dma buffer, so I
made it an allocated variable. Instead of adding a bunch of kfree()
calls, I changed all the error return paths to gotos.
Also I noticed that the error checking wasn't correct because
usb_get_descriptor() can return negative values.
While I was at it, I made an unrelated white space change by moving
the unicode_to_ascii() on to one line.

OMAP3 has three HS USB ports so it can have three different regulator
for each PHY connected to each port.
Currently these regulators are assumed to be optional and driver doesn't
fail but continue with the initialization if it doesn't get any regulators.
Regulator supply names has to be mapped in board files as 'hsusbN' where
'N' is port number and can be {0, 1 ,2}.

This patch fixes the Tx abort/teardown logic. We now wait for the teardown
completion interrupt and acknowledge the same by setting the tx_complete
register to 0.
This change is needed to ensure that abort processing works on DM365 platform.
Without this change after completion of abort processing the system is
overwhelmed with continuous stream of abort interrupts.
This change has been tested on all CPPI3.x platforms (DM644x, DM646x, DM35x,
DM36x).

This patch implements the work around for a Mentor controller related
bug where it's observed a BULK Tx toggle error on the bus when a
BULK IO gets scheduled on an endpoint that was earlier used for
handling ISOC transaction and needed to start on 1 toggle. When such
a situation arises even if the TXCSR toggle bits are programmed
correctly by the musb driver the data gets transmitted with 0 toggle
which leads to toggle error on the bus and the BULK transaction fails.
In case of MSC write, the device gets reset by the Host.
This Mentor bug is observed on almost all Mentor versions (1.3, 1.5,
1.8). Confirmed on DM644x, DM355, DM365, OMAPL13x platforms.

MUSB DMA_INTR register may sometimes read zero when infact there
was a pending interrupt. Workaround this by reading the DMA_COUNT
values for all enabled channels when this condition occurs.
Flag these channels as the ones needing to be serviced.
Additionally, the absence of a debug print meant we would never
catch a spurious DMA interrupt in MUSB. So this patch adds a
debug print in the IRQ handler.

We have observed MSC data read corruption when USB LAN device is
also connected and it's interface is up.
Silicon team has confirmed an errata where in all the active
transfers should use FIFO space either in first 8K or next 8K.
So far we have observed the issue in above use case scenario.
As a workaround to it, adding a new FIFO config (5) fitting well
within first 8K which can be used for such use cases.

Currently a non-root-hub USB device's wakeup settings are initialized when the
device is set to a configured state using device_init_wakeup(), but this is not
correct as wakeup is split into "capable" (can_wakeup) and "enabled"
(should_wakeup). The settings should be initialized instead in the device
initialization (usb_new_device) with the "capable" setting disabled and the
"enabled" setting enabled. The "capable" setting should be set based on the
device being configured or unconfigured, and "enabled" setting set based on
the sysfs power/wakeup control.
This patch retains the sysfs power/wakeup setting of a non-root-hub USB device
over a USB device re-configuration, which can happen (for example) after a
suspend/resume cycle.

Due to a simple oversight when bus zero was added, the text API fails to
deliver the bus number in 'E' messages (which are equivalent of 'C'
messages, only for error case). This makes it harder, for instance,
use a search-and-highlight in a text editor. So fix it.
Also, Alan Stern requested adding timestamps to 'E' messages. This is
purely cosmetic, but makes it easier to read the trace. This is done
for both text and binary APIs.
