The ehci and ohci drivers does not use the APIs of the usbhs
core driver; the runtime pm APIs are used for clock
enable/disable. Since usbhs is parent platform device of the
ehci and ohci devices, the runtime apis indirectly uses the
usb hs core device as input parameter to for clock functions.

New feature development
This adds support for new features, and contains stuff from most
platforms. A number of these patches could have fit into other
branches, too, but were small enough not to cause too much
confusion here.

Use an getter function in plat-orion/addr-map.c to get the address map
structure, rather than pass it to drivers in the platform_data
structures. When the drivers are built for none orion platforms, a
dummy function is provided instead which returns NULL.

Device tree conversions for samsung and tegra

much more to actually make it usable.

changes.

Rely on platform_data being passed through auxdata for now; more elaborate
bindings for phy config and tunings to be added.

fix up some simple but annoying merge conflicts.

builds:
drivers/usb/host/xhci-ring.c:1936:3: warning: format '%016llx' expects type 'long long unsigned int', but argument 3 has type 'dma_addr_t'

unsigned long long.

I encountered a result of COMP_2ND_BW_ERR while improving how the pwc
webcam driver handles not having the full usb1 bandwidth available to
itself.
I created the following test setup, a NEC xhci controller with a
single TT USB 2 hub plugged into it, with a usb keyboard and a pwc webcam
plugged into the usb2 hub. This caused the following to show up in dmesg
when trying to stream from the pwc camera at its highest alt setting:
xhci_hcd 0000:01:00.0: ERROR: unexpected command completion code 0x23.
usb 6-2.1: Not enough bandwidth for altsetting 9
And usb_set_interface returned -EINVAL, which caused my pwc code to not
do the right thing as it expected -ENOSPC.
This patch makes the xhci driver properly handle COMP_2ND_BW_ERR and makes
usb_set_interface return -ENOSPC as expected.
This should be backported to stable kernels as old as 2.6.32.

On some failures, the country_code field of an acm structure is freed
without freeing the acm structure itself. Elsewhere, operations including
memcpy and kfree are performed on the country_code field. The patch sets
the country_code field to NULL when it is freed, and likewise sets the
country_code_size field to 0.

Glue needs to be freed on exiting the function in an error case.
Furthermore, pci, which is the first argument to the probe function should
not be freed before leaveing the function, as it is reused at the call
site. So the free of pci is changed to free glue instead.
A simplified version of the semantic match that finds the problem is as
follows: (http://coccinelle.lip6.fr)

Add support for Chinese Noname HSPA USB modem which is apparently
manufactured by a company called ZD Incorporated (based on texts in the
Windows drivers).
This product is available at least from Dealextreme (SKU 80032) and
possibly in India with name Olive V-MW250. It is based on Qualcomm
MSM6280 chip.
I needed to also add "options usb-storage quirks=0685:7000:i" in modprobe
configuration because udevd or the kernel keeps poking the embedded
fake-cd-rom which fails and causes the device to reset. There might be
a better way to accomplish the same. usb_modeswitch is not needed with
this device.

According to USB 3.0 Specification Table 9-22, if
bmAttributes [4:0] are set to zero, it means "no
streams supported", but the way this helper was
defined on Linux, we will *always* have one stream
which might cause several problems.
For example on DWC3, we would tell the controller
endpoint has streams enabled and yet start transfers
with Stream ID set to 0, which would goof up the host
side.
While doing that, convert the macro to an inline
function due to the different checks we now need.

When a host controller gives a bad event TRB, we should print out the
contents of the TRB as a warning so that users don't have to recompile
their kernel to get information about what went wrong. Also, print out
the event ring if they have xHCI debugging turned on, since previous
events can often explain what happened before the bad TRB occurred.

With devices that can need up to 128 segments (with 64 TRBs per
segment), we can't afford to print out the entire endpoint ring every
time an URB is canceled. Instead, print the offset of the TRB, along
with device pathname and endpoint number.
Only print DMA addresses, since virtual addresses of internal structures
are not useful. Change the cancellation code to be more clear about
what steps of the cancellation it is in the process of doing (queueing
the request, handling the stop endpoint command, turning the TDs into
no-ops, or moving the dequeue pointers).

Debuggers only really care what the xHCI driver sets the ring dequeue
pointer to, so make the driver stop babbling about the memory addresses
of internal ring structures. This makes wading through the output of
allocating and freeing 256 stream rings much easier by reducing the
number of output lines per ring from 9 to 1.

The code for toggling the cycle bits when the ring wraps around has
worked for years. The print statement alone is not enough to indicate
there's something wrong with that code. Now that full transfer tracing
has been ripped out, the print statement or lack thereof won't help
without context of where the enqueue pointer is.

Remove verbose debugging about scatter-gather lists, as we haven't had

xHCI host controllers may not be capable of MSI, but they should be able
to be used in legacy PCI interrupt mode. Similarly, some xHCI host
controllers will have MSI support but not MSI-X support. Lower the
dmesg log level from an error to debug. The message won't appear unless
CONFIG_USB_XHCI_HCD_DEBUGGING is turned on.
If we need to find out whether the device can support MSI or MSI-X and
it's not being enabled by the driver, it's easy to ask the user to run
lspci.

Getting a short packet or a babble error is usually a recoverable error,
so stop scaring users with warnings in dmesg when xHCI debugging is turned

The xHCI driver will create an xhci_hcd structure, not an ehci_hci
structure.

When running the Point Grey "flycap" program for their USB 3.0 camera
(which was running as a USB 2.0 device for some reason), I trigger this
oops whenever I try to open a video stream:

This bug seems to have been introduced by commit
d178bc3a708f39cbfefc3fab37032d3f2511b4ec "user namespace: usb: make usb
urbs user namespace aware (v2)"
I'm not sure if this is right fix, but it does stop the oops.
Unfortunately, the Point Grey software still refuses to work, but it's a
closed source app, so I can't fix it.

add support for SG lists on dwc3 driver. With
this we can e.g. use VFS layer's SG lists on
storage gadgets so that we can start bigger
transfers and improve throughput.

the LST bit is to be set on the last of a series
of consecutive TRBs. We had a workaround for a
problem where data would get corrupted but that
doesn't happen anymore. It's likely that it was
caused by some FPGA instability during development
phase.

all that function does is setup a TRB to be sent
to HW later. There's no need to return anything
actually.

In order to make it easier to add SG support,
let's split the big loop out to its own function.

This is just a minor optimization for the long
if we have on the driver.
When we want to check that one input is true
and the other must be false, the bitwise XOR
operator will achieve that for us.
