Merge branch 'spear/dt' into next/dt 

This is a rebased version of parts of
  git://git.stlinux.com/spear/linux-2.6.git spear-v3.5

which was accidentally based on the linux-next tree and mixed too
many different things. The pinctrl related changes from the same
branch are now in the spear/pinctrl branch of arm-soc.

There are a few non-DT cleanups mixed in here, but fundamentally
it's all related to the DT conversion.

* spear/dt: (9 commits)
  ARM: spear: remove most mach/*.h header contents
  SPEAr: Update defconfigs
  SPEAr: Add PL080 DMA support for 3xx and 6xx
  ARM: SPEAr3xx: Add device-tree support to SPEAr3xx architecture
  SPEAr3xx: Replace printk() with pr_*()
  SPEAr6xx: Add compilation support for dtbs using 'make dtbs'
  SPEAr3xx: Add clock instance of usb hosts - ehci and ohci 0 and 1
  SPEAr: Use CLKDEV_INIT for defining clk_lookups
  ARM: SPEAr600: Change FSMC and SMI clock names

@ -168,6 +168,28 @@ that if the completion handler or anyone else tries to resubmit it
they will get a -EPERM error. Thus you can be sure that when
usb_kill_urb() returns, the URB is totally idle.
There is a lifetime issue to consider. An URB may complete at any
time, and the completion handler may free the URB. If this happens
while usb_unlink_urb or usb_kill_urb is running, it will cause a
memory-access violation. The driver is responsible for avoiding this,
which often means some sort of lock will be needed to prevent the URB
from being deallocated while it is still in use.
On the other hand, since usb_unlink_urb may end up calling the
completion handler, the handler must not take any lock that is held
when usb_unlink_urb is invoked. The general solution to this problem
is to increment the URB's reference count while holding the lock, then
drop the lock and call usb_unlink_urb or usb_kill_urb, and then
decrement the URB's reference count. You increment the reference
count by calling
struct urb *usb_get_urb(struct urb *urb)
(ignore the return value; it is the same as the argument) and
decrement the reference count by calling usb_free_urb. Of course,
none of this is necessary if there's no danger of the URB being freed
by the completion handler.
1.7. What about the completion handler?
