To avoid the error-proneness of calls to sizeof() in the memcpy,
this patch uses struct assignment instead of memcpy.

This patch is based on Greg's linux-usb.git / usb-next branch.
Note that mod_host.c also has memcpy but we cannot use struct assignment
for it because the type of urb->setup_patcket is just "unsigned char *".

snprintf returns the actual length of the buffer created; however,
this is not the case if snprintf truncates its parameter.
See https://lwn.net/Articles/69419/ for a detailed explanation.
The current code correctly handles this case at the expense
of extra code in the return statement.
scnprintf does returns the actual length of the buffer created
making the ?: operator unnecessary in the return
statement.
This change does not alter the functionality of the code.

USB 3.2 capability in a host can be detected from the
xHCI Supported Protocol Capability major and minor revision fields.
If major is 0x3 and minor 0x20 then the host is USB 3.2 capable.
For USB 3.2 capable hosts set the root hub lane count to 2.
The Major Revision and Minor Revision fields contain a BCD version number.
The value of the Major Revision field is JJh and the value of the Minor
Revision field is MNh for version JJ.M.N, where JJ = major revision number,
M - minor version number, N = sub-minor version number,
e.g. version 3.1 is represented with a value of 0310h.
Also fix the extra whitespace printed out when announcing regular
SuperSpeed hosts.

A USB3 device needs to be reset and re-enumarated if the port it
connects to goes to a error state, with link state inactive.
There is no use in trying to recover failed transactions by resetting
endpoints at this stage. Tests show that in rare cases, after multiple
endpoint resets of a roothub port the whole host controller might stop
completely.
Several retries to recover from transaction error can happen as
it can take a long time before the hub thread discovers the USB3
port error and inactive link.
We can't reliably detect the port error from slot or endpoint context
due to a limitation in xhci, see xhci specs section 4.8.3:
"There are several cases where the EP State field in the Output
Endpoint Context may not reflect the current state of an endpoint"
and
"Software should maintain an accurate value for EP State, by tracking it
with an internal variable that is driven by Events and Doorbell accesses"
Same appears to be true for slot state.
set a flag to the corresponding slot if a USB3 roothub port link goes
inactive to prevent both queueing new URBs and resetting endpoints.

This change is to fix below warning message in following scenario:
usb_composite_setup_continue: Unexpected call
When system tried to enter suspend, the fsg_disable() will be called to
disable fsg driver and send a signal to fsg_main_thread. However, at
this point, the fsg_main_thread has already been frozen and can not
respond to this signal. So, this signal will be pended until
fsg_main_thread wakes up.
Once system resumes from suspend, fsg_main_thread will detect a signal
pended and do some corresponding action (in handle_exception()). Then,
host will send some setup requests (get descriptor, set configuration...)
to UDC driver trying to enumerate this device. During the handling of "set
configuration" request, it will try to sync up with fsg_main_thread by
sending a signal (which is the same as the signal sent by fsg_disable)
to it. In a similar manner, once the fsg_main_thread receives this
signal, it will call handle_exception() to handle the request.
However, if the fsg_main_thread wakes up from suspend a little late and
"set configuration" request from Host arrives a little earlier,
fsg_main_thread might come across the request from "set configuration"
when it handles the signal from fsg_disable(). In this case, it will
handle this request as well. So, when fsg_main_thread tries to handle
the signal sent from "set configuration" later, there will nothing left
to do and warning message "Unexpected call" is printed.

Gadget applications may have a requirement to disable the U1 and U2
entry based on the usecase. Below are few usecases where the disabling
U1/U2 entries may be possible.
Usecase 1:
When combining dwc3 with an redriver for a USB Type-C device solution, it
sometimes have problems with leaving U1/U2 for certain hosts, resulting in
link training errors and reconnects. For this U1/U2 state entries may be
avoided.
Usecase 2:
When performing performance benchmarking on mass storage gadget the
U1 and U2 entries can be disabled.
Usecase 3:
When periodic transfers like ISOC transfers are used with bInterval
of 1 which doesn't require the link to enter into U1 or U2 state entry
(since ping is issued from host for every uframe interval). In this
case the U1 and U2 entry can be disabled.
Disablement of U1/U2 can be done by setting U1DevExitLat and U2DevExitLat
values to 0 in the BOS descriptor. Host on seeing 0 value for U1DevExitLat
and U2DevExitLat, it doesn't send SET_SEL requests to the gadget. There
may be some hosts which may send SET_SEL requests even after seeing 0 in
the UxDevExitLat of BOS descriptor. To aviod U1/U2 entries for these type
of hosts, dwc3 controller can be programmed to reject those U1/U2 requests
by not enabling ACCEPTUxENA bits in DCTL register.
This patch updates the same.

The required clocks needs to be enabled before the first register
access. After commit fe8abf332b8f ("usb: dwc3: support clocks and resets
for DWC3 core"), this happens when the dwc3_core_is_valid function is
called, but the mentioned commit adds that call in the wrong place,
before the clocks are enabled. So, move that call after the
clk_bulk_enable() to ensure the clocks are enabled and the reset
deasserted.
I detected this while, as experiment, I tried to move the clocks and resets
from the glue layer to the DWC3 core on a Samsung Chromebook Plus.
That was not detected before because, in most cases, the glue layer
initializes SoC-specific things and then populates the child "snps,dwc3"
with those clocks already enabled.

dwc3_qcom_clk_init() is called with of_count_phandle_with_args() as an
argument. If of_count_phandle_with_args() returns an error, the number
of clocks will be a negative value and will lead to undefined behaviour.

When booting with Device Tree, the current default boot configuration
table option, the request to boot via 'host mode' comes from the
'dr_mode' property. A property of the same name can be used inside
ACPI tables too. However it is missing from the SDM845's ACPI tables
so we have to supply this information using Platform Device Properties
instead.
This does not change the behaviour of any currently supported devices.
The property is only set on ACPI enabled platforms, thus for H/W
booting DT, unless a 'dr_mode' property is present, the default is
still OTG (On-The-Go) as per [0]. Any new ACPI devices added will
also be able to over-ride this implementation by providing a 'dr_mode'
property in their ACPI tables. In cases where 'dr_mode' is omitted
from the tables AND 'host mode' should not be the default (very
unlikely), then we will have to add some way of choosing between them
at run time - most likely by ACPI HID.

In Linux, the DWC3 core exists as its own independent platform device.
Thus when describing relationships in Device Tree, the current default
boot configuration table option, the DWC3 core often resides as a child
of the platform specific node. Both of which are given their own
address space descriptions and the drivers can be mostly agnostic to
each other.
However, other Operating Systems have taken a more monolithic approach,
which is evident in the configuration ACPI tables for the Qualcomm
Snapdragon SDM850, where all DWC3 (core and platform) components are
described under a single IO memory region.
To ensure successful booting using the supplied ACPI tables, we need to
devise a way to chop up the address regions provided and subsequently
register the DWC3 core with the resultant information, which is
precisely what this patch aims to achieve.

In some cases the "Allocate & copy" block in ffs_epfile_io() is not
executed. Consequently, in such a case ffs_alloc_buffer() is never called
and struct ffs_io_data is not initialized properly. This in turn leads to
problems when ffs_free_buffer() is called at the end of ffs_epfile_io().
This patch uses kzalloc() instead of kmalloc() in the aio case and memset()
in non-aio case to properly initialize struct ffs_io_data.

The following line of code in function ffs_epfile_io is trying to set
flag io_data->use_sg in case buffer required is larger than one page.
io_data->use_sg = gadget->sg_supported && data_len > PAGE_SIZE;
However at this point of time the variable data_len has not been set
to the proper buffer size yet. The consequence is that io_data->use_sg
is always set regardless what buffer size really is, because the condition
(data_len > PAGE_SIZE) is effectively an unsigned comparison between
-EINVAL and PAGE_SIZE which would always result in TRUE.

If the 'snps,need-phy-for-wake' is set in the device tree then:
- We know that we can wakeup, so call device_set_wakeup_capable().
The USB core will use this knowledge to enable wakeup by default.
- We know that we should keep the PHY on during suspend if something
on our root hub needs remote wakeup. This requires the patch (USB:
Export usb_wakeup_enabled_descendants()). Note that we don't keep
the PHY on at suspend time if it's not needed because it would be a
power draw.
If we later find some users of dwc2 that can support wakeup without
keeping the PHY on we may want to add a way to call
device_set_wakeup_capable() without keeping the PHY on at suspend
time.

it's value will be overwritten by dwc2_init_params().
This change make sure to take in account the generic PHY width information
during paraminitialisation, done in dwc2_set_param_phy_utmi_width().
By doing so, the phy_utmi_width params can still be overrided by
devicetree specific params and will also be checked against hardware

Recently usfbs gained availability to retrieve device speed, but there
is sill no way to determine the bus number or list of ports the device
is connected to when using usbfs. While this information can be obtained
from sysfs, not all environments allow sysfs access. In a jailed
environment a program might be simply given an opened file descriptor to
usbfs device, and it is really important that all data can be gathered
from said file descriptor.
This patch introduces a new ioctl, USBDEVFS_CONNINFO_EX, which return
extended connection information for the device, including the bus
number, address, port list and speed. The API allows kernel to extend
amount of data returned by the ioctl and userspace has an option of
adjusting the amount of data it is willing to consume. A new capability,
USBDEVFS_CAP_CONNINFO_EX, is introduced to help userspace in determining
whether the kernel supports this new ioctl.

An endpoint conflict occurs when the USB is working in device mode
during an isochronous communication. When the endpointA IN direction
is an isochronous IN endpoint, and the host sends an IN token to
endpointA on another device, then the OUT transaction may be missed
regardless the OUT endpoint number. Generally, this occurs when the
device is connected to the host through a hub and other devices are
connected to the same hub.
The affected OUT endpoint can be either control, bulk, isochronous, or
an interrupt endpoint. After the OUT endpoint is primed, if an IN token
to the same endpoint number on another device is received, then the OUT
endpoint may be unprimed (cannot be detected by software), which causes
this endpoint to no longer respond to the host OUT token, and thus, no
corresponding interrupt occurs.
There is no good workaround for this issue, the only thing the software
could do is numbering isochronous IN from the highest endpoint since we
have observed most of device number endpoint from the lowest.
