crypto: sha512 - Fix byte counter overflow in SHA-512

The current code only increments the upper 64 bits of the SHA-512 byte
counter when the number of bytes hashed happens to hit 2^64 exactly.

This patch increments the upper 64 bits whenever the lower 64 bits
overflows.

usb: gadget: udc-core: stop UDC on device-initiated disconnect

When we want to do device-initiated disconnect,
let's make sure we stop the UDC in order to
e.g. allow lower power states to be achieved by
turning off unnecessary clocks and/or stoping
PHYs.

When reconnecting, call ->udc_start() again to
make sure UDC is reinitialized.

usb: musb: fix oops on omap2430 module unload

This change prevents runtime suspend and resume actual execution, if
omap2430 controller driver is loaded after musb-hdrc, and therefore the
controller isn't initialized properly.

The problem is reproducible with 3.1.y and 3.2 kernels.

Kernel configuration of musb:

  % cat .config | egrep 'MUSB|GADGET'
  CONFIG_USB_MUSB_HDRC=y
  # CONFIG_USB_MUSB_TUSB6010 is not set
  CONFIG_USB_MUSB_OMAP2PLUS=m
  # CONFIG_USB_MUSB_AM35X is not set
  CONFIG_MUSB_PIO_ONLY=y
  CONFIG_USB_GADGET=y
  # CONFIG_USB_GADGET_DEBUG is not set
  # CONFIG_USB_GADGET_DEBUG_FILES is not set
  # CONFIG_USB_GADGET_DEBUG_FS is not set
  CONFIG_USB_GADGET_VBUS_DRAW=2
  CONFIG_USB_GADGET_STORAGE_NUM_BUFFERS=2
  CONFIG_USB_GADGET_MUSB_HDRC=m
  CONFIG_USB_GADGET_DUALSPEED=y
  CONFIG_USB_GADGETFS=m
  # CONFIG_USB_MIDI_GADGET is not set

Fixes the following oops on module unloading:

usb: musb: fix some runtime_pm issues

When runtime_pm was originally added, it was done in rather confusing
way: omap2430_musb_init() (called from musb_init_controller) would do
runtime_pm_get_sync() and musb_init_controller() itself would do
runtime_pm_put to balance it out. This is not only confusing but also
wrong if non-omap2430 glue layer is used.

This confusion resulted in commit 772aed45b604 "usb: musb: fix
pm_runtime mismatch", that removed runtime_pm_put() from
musb_init_controller as that looked unbalanced, and also happened to
fix unrelated isp1704_charger crash. However this broke runtime PM
functionality (musb is now always powered, even without gadget active).

Avoid these confusing runtime pm dependences by making
musb_init_controller() and omap2430_musb_init() do their own runtime
get/put pairs; also cover error paths. Remove unneeded runtime_pm_put
in omap2430_remove too. isp1704_charger crash that motivated
772aed45b604 will be fixed by following patch.

usb: fsl_udc_core: prime status stage once data stage has primed

- For Control Read transfer, the ACK handshake on an IN transaction
may be corrupted, so the device may not receive the ACK for data
stage, the complete irq will not occur at this situation.
Therefore, we need to move prime status stage from complete irq
routine to the place where the data stage has just primed, or the
host will never get ACK for status stage.
The above issue has been described at USB2.0 spec chapter 8.5.3.3.

- After adding prime status stage just after prime the data stage,
there is a potential problem when the status dTD is added before the data stage
has primed by hardware. The reason is the device's dTD descriptor has NO direction bit,
if data stage (IN) prime hasn't finished, the status stage(OUT)
dTD will be added at data stage dTD's Next dTD Pointer, so when the data stage
transfer has finished, the status dTD will be primed as IN by hardware,
then the host will never receive ACK from the device side for status stage.

- Delete below code at fsl_ep_queue:
       /* Update ep0 state */
       if ((ep_index(ep) == 0))
               udc->ep0_state = DATA_STATE_XMIT;
the udc->ep0_state will be updated again after udc->driver->setup
finishes.

It is tested at i.mx51 bbg board with g_mass_storage, g_ether, g_serial.

Control transfers with data expected from device to host will use usb_rcvctrlpipe()

usb: musb: wake the device before ulpi transfers

musb can be suspended at the time some other driver wants to do ulpi
transfers using usb_phy_io_* functions, and that can cause data abort,
as it happened with isp1704_charger:
http://article.gmane.org/gmane.linux.kernel/1226122

Add pm_runtime to ulpi functions to rectify this. This also adds io_dev
to usb_phy so that pm_runtime_* functions can be used.
