Rename SCSI_MAX_SG_SEGMENTS to SG_CHUNK_SIZE, which means the amount
we fit into a single scatterlist chunk.
Rename SCSI_MAX_SG_CHAIN_SEGMENTS to SG_MAX_SEGMENTS.
Will move these 2 generic definitions to scatterlist.h later.

Pull ARM SoC driver updates from Arnd Bergmann:
"Driver updates for ARM SoCs, these contain various things that touch
the drivers/ directory but got merged through arm-soc for practical
reasons.
For the most part, this is now related to power management
controllers, which have not yet been abstracted into a separate
subsystem, and typically require some code in drivers/soc or arch/arm
to control the power domains.
Another large chunk here is a rework of the NVIDIA Tegra USB3.0
support, which was surprisingly tricky and took a long time to get
done.
Finally, reset controller handling as always gets merged through here
as well"

Add support for the on-chip XUSB controller present on Tegra SoCs. This
controller, when loaded with external firmware, exposes an interface
compliant with xHCI. This driver loads the firmware, starts the
controller, and is able to service host-specific messages sent by the
controller's firmware.
The controller also supports USB device mode as well as powergating
of the SuperSpeed and host-controller logic when not in use, but
support for these is not yet implemented.

This reverts commit e3345db85068ddb937fc0ba40dfc39c293dad977, which
broke system resume for a large class of devices.
Devices that after having been reset during resume need to be rebound
due to a missing reset_resume callback, are now left in a suspended
state. This specifically broke resume of common USB-serial devices,
which are now unusable after system suspend (until disconnected and
reconnected) when USB persist is enabled.
During resume, usb_resume_interface will set the needs_binding flag for
such interfaces, but unlike system resume, run-time resume does not
honour it.

When using asynchronous read or write operations on the USB endpoints the
issuer of the IO request is notified by calling the ki_complete() callback
of the submitted kiocb when the URB has been completed.
Calling this ki_complete() callback will free kiocb. Make sure that the
structure is no longer accessed beyond that point, otherwise undefined
behaviour might occur.

Otherwise generic-xhci and xhci-platform which have no data get wrongly
detected as XHCI_PLAT_TYPE_MARVELL_ARMADA by xhci_plat_type_is().
This fixes a regression in v4.5 for STiH407 family SoC's which use the
synopsis dwc3 IP, whereby the disable_clk error path gets taken due to
wrongly being detected as XHCI_PLAT_TYPE_MARVELL_ARMADA and the hcd never
gets added.
I suspect this will also fix other dwc3 DT platforms such as Exynos,
although I've only tested on STih410 SoC.

PCI hotpluggable xhci controllers such as some Alpine Ridge solutions will
remove the xhci controller from the PCI bus when the last USB device is
disconnected.
Add a flag to indicate that the host is being removed to avoid queueing
configure_endpoint commands for the dropped endpoints.
For PCI hotplugged controllers this will prevent 5 second command timeouts
For static xhci controllers the configure_endpoint command is not needed
in the removal case as everything will be returned, freed, and the
controller is reset.
For now the flag is only set for PCI connected host controllers.

On some xHCI controllers (e.g. R-Car SoCs), the AC64 bit (bit 0) of
HCCPARAMS1 is set to 1. However, the xHCs don't support 64-bit
address memory pointers actually. So, in this case, this driver should
call dma_set_coherent_mask(dev, DMA_BIT_MASK(32)) in xhci_gen_setup().
Otherwise, the xHCI controller will be died after a usb device is
connected if it runs on above 4GB physical memory environment.
So, this patch adds a new quirk XHCI_NO_64BIT_SUPPORT to resolve
such an issue.

A Fedora user reports that the ftdi_sio driver works properly for the
ICP DAS I-7561U device. Further, the user manual for these devices
instructs users to load the driver and add the ids using the sysfs
interface.
Add support for these in the driver directly so that the devices work
out of the box instead of needing manual configuration.

usb: fixes for v4.6-rc3
We have two more fixes to f_midi. It should now
behave much better.
dwc3-keystone.c has gotten a fix which now allows it
to work on keystone device when running in
peripheral mode. A similar fix for DMA configuration
was made for udc-core, too.
We have a new PCI ID for Intel's Broxton
platform. DWC3 can run on those platforms as well.
And we also have some dwc2 got a fix for dr_mode
usage, while renesas controller got 3 important
fixes: a NULL pointer deref fix, IRQ <-> DMA race
fix, and a fix to prevent a situation where we would
queue a request to a disabled endpoint.

The Keystone 2 supports DT-boot only, as result dma_mask will be
always configured properly from DT -
of_platform_device_create_pdata()->of_dma_configure(). More over,
dwc3-keystone.c can be built as module and in this case it's unsafe to
assign local variable as dma_mask.
Hence, remove dma_mask configuration code.

Since commit 7ace8fc8219e ("usb: gadget: udc: core: Fix argument of

This patch fixes an issue that usbhsg_queue_done() may cause kernel
panic when dma callback is running and usb_ep_disable() is called
by interrupt handler. (Especially, we can reproduce this issue using
g_audio with usb-dmac driver.)
For example of a flow:
usbhsf_dma_complete (on tasklet)
--> usbhsf_pkt_handler (on tasklet)
--> usbhsg_queue_done (on tasklet)
*** interrupt happened and usb_ep_disable() is called ***
--> usbhsg_queue_pop (on tasklet)
Then, oops happened.

buflen by default (256) is smaller than wMaxPacketSize (512) in high-speed
devices.
That caused the OUT endpoint to freeze if the host send any data packet of
length greater than 256 bytes.
This is an example dump of what happended on that enpoint:
HOST: [DATA][Length=260][...]
DEVICE: [NAK]
HOST: [PING]
DEVICE: [NAK]
HOST: [PING]
DEVICE: [NAK]
...
HOST: [PING]
DEVICE: [NAK]
This patch fixes this problem by setting the minimum usb_request's buffer size
for the OUT endpoint as its wMaxPacketSize.
