Graeme Gregory 5ccee4ae8e USB: TWL6025 allow different regulator name
The twl6025 uses a different regulator for USB than the 6030 so select
the correct regulator name depending on the subclass of device.

Since V1

Use features passed via platform data instead of global variable.

Linus Torvalds 268bb0ce3e sanitize <linux/prefetch.h> usage
Commit e66eed651f ("list: remove prefetching from regular list
iterators") removed the include of prefetch.h from list.h, which
uncovered several cases that had apparently relied on that rather
obscure header file dependency.

So this fixes things up a bit, using

   grep -L linux/prefetch.h $(git grep -l '[^a-z_]prefetchw*(' -- '*.[ch]')
   grep -L 'prefetchw*(' $(git grep -l 'linux/prefetch.h' -- '*.[ch]')

to guide us in finding files that either need <linux/prefetch.h>
inclusion, or have it despite not needing it.

There are more of them around (mostly network drivers), but this gets
many core ones.

This patch adds support for big endian GRUSBHC UHCI controllers.
The HCD bus glue will probe the register interface to determine
the endianness of the controller.

Tested on GR-LEON4-ITX board which has a controller with little endian
interface and on custom LEON3 board with a BE controller.

Jan Andersson 51e2f62fe7 USB: UHCI: Add support for big endian descriptors
This patch adds support for universal host controllers that use
big endian descriptors. Support for BE descriptors requires a non-PCI
host controller. For kernels with PCI-only UHCI there should be no
change in behaviour.

This patch tries to replicate the technique used to support BE descriptors
in the EHCI HCD. Parts added to uhci-hcd.h are basically copy'n'paste from
ehci.h.

This patch (as1462) updates the special accessor functions defined in
uhci-hcd.h.  Rather than using a full compiler barrier, all we really
need is the ACCESS_ONCE() mechanism, because the idea is to force the
compiler to store a fixed copy of a possibly changing value.

This patch adds support for big endian mmio to the UHCI HCD. Big endian
mmio is supported by adding a flag bit to the UHCI HCD replicating the
solution used in the EHCI HCD.

When adding big endian support this patch also adds a check to see if we
need to support HCs with PCI I/O registers when we support HCs with MMIO.

This patch also adds 'const' to the register access functions' uhci_hcd

Preparation for patch #2. The function isp1760_endpoint_disable() does almost
the same thing as urb_dequeue(). In patch #2 I change these to use a common
helper function instead of calling each other - for clarity but also to
avoid releasing the spinlock while in a "questionable" state. It seemed
proper to have these functions close to each other in the code.

Alan Stern 69fff59de4 USB: remove remaining usages of hcd->state from usbcore and fix regression
This patch (as1467) removes the last usages of hcd->state from
usbcore.  We no longer check to see if an interrupt handler finds that
a controller has died; instead we rely on host controller drivers to
make an explicit call to usb_hc_died().

This fixes a regression introduced by commit
9b37596a2e (USB: move usbcore away from
hcd->state).  It used to be that when a controller shared an IRQ with
another device and an interrupt arrived while hcd->state was set to
HC_STATE_HALT, the interrupt handler would be skipped.  The commit
removed that test; as a result the current code doesn't skip calling
the handler and ends up believing the controller has died, even though
it's only temporarily stopped.  The solution is to ignore HC_STATE_HALT
following the handler's return.

As a consequence of this change, several of the host controller
drivers need to be modified.  They can no longer implicitly rely on
usbcore realizing that a controller has died because of hcd->state.
The patch adds calls to usb_hc_died() in the appropriate places.

The patch also changes a few of the interrupt handlers.  They don't
expect to be called when hcd->state is equal to HC_STATE_HALT, even if
the controller is still alive.  Early returns were added to avoid any
confusion.

Grant Likely b1608d69cb drivercore: revert addition of of_match to struct device
Commit b826291c, "drivercore/dt: add a match table pointer to struct
device" added an of_match pointer to struct device to cache the
of_match_table entry discovered at driver match time.  This was unsafe
because matching is not an atomic operation with probing a driver.  If
two or more drivers are attempted to be matched to a driver at the
same time, then the cached matching entry pointer could get
overwritten.

This patch reverts the of_match cache pointer and reworks all users to
call of_match_device() directly instead.

Alan Stern 1e12c910ee EHCI: don't rescan interrupt QHs needlessly
This patch (as1466) speeds up processing of ehci-hcd's periodic list.
The existing code will pointlessly rescan an interrupt endpoint queue
each time it encounters the queue's QH in the periodic list, which can
happen quite a few times if the endpoint's period is low.  On some
embedded systems, this useless overhead can waste so much time that
the driver falls hopelessly behind and loses events.

The patch introduces a "periodic_stamp" variable, which gets
incremented each time scan_periodic() runs and each time the scan
advances to a new frame.  If the corresponding stamp in an interrupt
QH is equal to the current periodic_stamp, we assume the QH has
already been scanned and skip over it.  Otherwise we scan the QH as
usual, and if none of its URBs have completed then we store the
current periodic_stamp in the QH's stamp, preventing it from being
scanned again.
