Just like we did for all other endpoint types, let's rely on a chained
TRB pointing to ep0_bounce_addr in order to align transfer size. This
will make the code simpler.

If we pass TRB's own address on bpl/bph fields, we can get our SETUP

There are several inconsistencies in the error handling code.
1. If clk_get() fails, it goes to clk_put().
2. If pdata->phy_init() fails, it does not disable u3d->clk.
3. In case of failure after stopping u3d, it does pdata->phy_deinit()
and clk_disable(u3d->clk) twice.
4. It ignores failures in clk_enable().

This patch splits the amd5536udc driver into two -- one that does
pci device registration and the other file that does the rest of
the driver tasks like the gadget/ep ops etc for Synopsys UDC.
This way of splitting helps in exporting core driver symbols which
can be used by any other platform/pci driver that is written for
the same Synopsys USB device controller.
The current patch also includes a change in the Kconfig and Makefile.
A new config option USB_SNP_CORE will be selected automatically when
any one of the platform or pci driver for the same UDC is selected.
Main changes:
- amd5536udc_pci.c: PCI device registration is moved to this file.
- amd5536udc.c:
This file does rest of the core UDC fucntionality.
9 symbols are exported so as to be used by amd5536udc_pci.c.
Module parameter definitions are moved to header file.
- amd5536udc.h:
Function declarations, module parameters definitions and few common
header file includes are added to this file
- Kconfig:
New USB_SNP_CORE option is added which will be auto selected when
any pci or platform driver config option for the UDC is chosen.
- Makefile:
Compiles the core and pci files separately.

This patch adds support for usb role swap via sysfs "role".
For example:
1) Connect a usb cable using 2 Salvator-X boards.
- For A-Device, the cable is connected to CN11 (USB3.0 ch0).
- For B-Device, the cable is connected to CN9 (USB2.0 ch0).
2) On A-Device, you input the following command:
# echo peripheral > /sys/devices/platform/soc/ee020000.usb/role
3) On B-Device, you input the following command:
# echo host > /sys/devices/platform/soc/ee080200.usb-phy/role
Then, the A-Device acts as a peripheral and the B-Device acts as
a host. Please note that A-Device must input the following command
if you want the board to act as a host again.
# echo host > /sys/devices/platform/soc/ee020000.usb/role

Currently ffs_dev::name can be either allocated by the client of
the ffs_dev structure or by the f_fs.c core itself. The former
is used by g_ffs while the latter happens with configfs.
Historically, g_ffs did not need to allocate separate buffer for
the name so what is now f_fs.c core never cared about freeing
that space. With configfs the name needs to be copied since the
memory is not guaranteed to be availeble after ffs_set_inst_name
finishes.
The complication is therefore here to avoid allocations in the
g_ffs case but it complicates the code inproportinally to
benefits it provides. In particular, g_ffs is considered
‘legacy’ so optimising for its sake is unlikely to be worth the
effort.
With that observation in mind, simplify the code by unifying the
code paths in g_ffs and configfs paths. Furthermore, instead of
allocating a new buffer for the name, simply embed it in the
ffs_dev structure. This further makes the memory management
less convoluted and error-prone.
The configfs interface for functionfs imposed a limit of 40
characters for the name so this results in a 41-byte buffer
added to the structure. (For short names this may lead to
wasted memory but the actual amount is not immediately obvious
and depends on pointer size and which slab buckets the structure
and name would fall into).

As USB_CONFIGFS is not a part of the "USB Gadget Drivers" choice
anymore, the name for the option and its attached description needs to
be more descriptive. It appears one level higher in the configuration
menu, and without the context provided by the comments for the choice
entry, it needs to make sense on its own.
Conversely, the "USB Gadget Drivers" entry now only introduces the
legacy drivers, where one or more functions are combined in a single
driver. As the configfs option can be used as a full-fledged
alternative, rename the choice entry to show that it is not the only
way to provice service as an USB gadget.

With commit bc49d1d17dcf ("usb: gadget: don't couple configfs to legacy
gadgets"),it is possible to build a modular kernel with both built-in
configfs support and modular legacy gadget drivers.
But when building a kernel without modules, it is also necessary to be
able to build with configfs but without any legacy gadget driver. This
was a possible configuration when the USB_CONFIGFS was a part of the
choice options, but not anymore.
Mark the choice for legacy gadget drivers as optional restores this.

The gadget wants to set the starting microframe for the first ISOC TRB
to 4 microframes in the future, but it does so by multiplying the
dep->interval. This only works if dep->interval = 1. For other intervals
it will put it 4 *intervals* in the future which may be way too much.
Fix so that it always adds just one interval or at least 4 microframes.

- DWC_USB3_NUM indicates the number of Device mode single directional
endpoints, including OUT and IN endpoint 0.
- DWC_USB3_NUM_IN_EPS indicates the maximum number of Device mode IN
endpoints active at any time, including control endpoint 0.
It's possible to configure RTL such that DWC_USB3_NUM_EPS is equal to
DWC_USB3_NUM_IN_EPS.
dwc3-core calculates the number of OUT endpoints as DWC_USB3_NUM minus
DWC_USB3_NUM_IN_EPS. If RTL has been configured with DWC_USB3_NUM_IN_EPS
equal to DWC_USB3_NUM then dwc3-core will calculate the number of OUT
endpoints as zero.
For example a from dwc3_core_num_eps() shows:
[ 1.565000] /usb0@f01d0000: found 8 IN and 0 OUT endpoints
This patch refactors the endpoint calculation down to one variable
dwc->num_eps taking care to maintain the current mapping of endpoints for
fixed FPGA configurations as described in Table 4-7 of version 2.60a of the
DWC USB3 databook.
The endpoint mapping will then be EP-OUT, EP-IN etc, up to DWC_USB3_NUM.
If DWC_USB3_NUM is odd then OUT will take the extra endpoint.

I had seen some odd behavior with HiKey's usb-gadget interface
that I finally seemed to have chased down. Basically every other
time I plugged in the OTG port, the gadget interface would
properly initialize. The other times, I'd get a big WARN_ON
in dwc2_hsotg_init_fifo() about the fifo_map not being clear.
Ends up if we don't disconnect the gadget state, the fifo-map
doesn't get cleared properly, which causes WARN_ON messages and
also results in the device not properly being setup as a gadget
every other time the OTG port is connected.
So this patch adds a call to dwc2_hsotg_disconnect() in the
reset path so the state is properly cleared.
With it, the gadget interface initializes properly on every
plug in.

Pull rdma fixes from Doug Ledford:
"This has been a slow -rc cycle for the RDMA subsystem. We really
haven't had a lot of rc fixes come in. This pull request is the first
of this entire rc cycle and it has all of the suitable fixes so far
and it's still only about 20 patches. The fix for the minor breakage
cause by the dma mapping patchset is in here, as well as a couple
other potential oops fixes, but the rest is more minor.
Summary:
- fix for dma_ops change in this kernel, resolving the s390, powerpc,
and IOMMU operation
- a few other oops fixes
- the rest are all minor fixes"

one where we need to copy a string because we can't guarantee it isn't
freed sometime later"

aarch64-linux-gcc-7 complains about code it doesn't fully understand:
drivers/infiniband/hw/qib/qib_iba7322.c: In function 'qib_7322_txchk_change':
include/asm-generic/bitops/non-atomic.h:105:35: error: 'shadow' may be used uninitialized in this function [-Werror=maybe-uninitialized]
The code is right, and despite trying hard, I could not come up with a version
that I liked better than just adding a fake initialization here to shut up the
warning.
