USB: Changes for v5.4 merge window
With only 45 non-merge commits, we have a small merge window from the
Gadget perspective.
The biggest change here is the addition of the Cadence USB3 DRD
Driver. All other changes are small, non-critical fixes or smaller new
features like the improvement to BESL handling in dwc3.

We don't need dev_err() messages when platform_get_irq() fails now that
platform_get_irq() prints an error message itself when something goes
wrong. Let's remove these prints with a simple semantic patch.

expression ret;
struct platform_device *E;

ret =

platform_get_irq(E, ...)

platform_get_irq_byname(E, ...)

Now that the SPDX tag is in all USB files, that identifies the license
in a specific and legally-defined manner. So the extra GPL text wording
can be removed as it is no longer needed at all.
This is done on a quest to remove the 700+ different ways that files in
the kernel describe the GPL license text. And there's unneeded stuff
like the address (sometimes incorrect) for the FSF which is never
needed.
No copyright headers or other non-license-description text was removed.

It's good to have SPDX identifiers in all files to make it easier to
audit the kernel tree for correct licenses.
Update the drivers/usb/ and include/linux/usb* files with the correct
SPDX license identifier based on the license text in the file itself.
The SPDX identifier is a legally binding shorthand, which can be used
instead of the full boiler plate text.
This work is based on a script and data from Thomas Gleixner, Philippe
Ombredanne, and Kate Stewart.

platform_get_irq() returns an error code, but the dwc3-omap driver
ignores it and always returns -EINVAL. This is not correct and,
prevents -EPROBE_DEFER from being propagated properly.
Notice that platform_get_irq() no longer returns 0 on error:
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=e330b9a6bb35dc7097a4f02cb1ae7b6f96df92af

IRQ_NOAUTOEN cannot be used with shared IRQs, since commit 04c848d39879
("genirq: Warn when IRQ_NOAUTOEN is used with shared interrupts") and
kernel now throws a warn dump. But OMAP DWC3 driver uses this flag. As
per commit 12a7f17fac5b ("usb: dwc3: omap: fix race of pm runtime with
irq handler in probe") that introduced this flag, PM runtime can race
with IRQ handler when deferred probing happens due to extcon,
therefore IRQ_NOAUTOEN needs to be set so that irq is not enabled until
extcon is registered.
Remove setting of IRQ_NOAUTOEN and move the registration of
shared irq to a point after dwc3_omap_extcon_register() and
of_platform_populate(). This avoids possibility of probe deferring and
above said race condition.

Now races can happen between interrupt handler execution and PM runtime in
error handling code path in probe and in dwc3_omap_remove() which will lead
to system crash:
in probe:
...
err1:
pm_runtime_put_sync(dev);
^^ PM runtime can race with IRQ handler when deferred probing happening
due to extcon
pm_runtime_disable(dev);
return ret;
in dwc3_omap_remove:
...
dwc3_omap_disable_irqs(omap);
^^ IRQs are disabled in HW, but handler may still run
of_platform_depopulate(omap->dev);
pm_runtime_put_sync(&pdev->dev);
^^ PM runtime can race with IRQ handler
pm_runtime_disable(&pdev->dev);
return 0;
So, OMAP DWC3 IRQ need to be disabled before calling
pm_runtime_put() in probe and in dwc3_omap_remove().

[1] OMAP542x TRM - http://www.ti.com/lit/pdf/swpu249
Section 23.11.4.5.1 Mailbox VBUS/ID Management
"Because PIPE powerpresent has a different meaning in host and in device mode,
and because of the redundancy with the UTMI signals, the controller ORes
together the appropriate PIPE and UTMI inputs to create its internal
VBUS status. For that reason, it is recommended to leave field
USBOTGSS_UTMI_OTG_STATUS[9] POWERPRESENT at its default value (=0), and only to

We intend to share this interrupt with the OTG driver an to ensure
that irqflags match for the shared interrupt handlers we use
request_threaded_irq()
If we don't use request_treaded_irq() then forced threaded irq will
set IRQF_ONESHOT and this won't match with the OTG IRQ handler's
IRQ flags.
NOTE: OTG IRQ handler is yet to be added. This is a preparatory step.

usb: changes for v4.7 merge window
Here's the big USB Gadget pull request. This time
not as large as usual with only 57 non-merge
commits.
The most important part here is, again, all the work
on dwc3. This time around we're treating all
endpoints (except for control endpoint) exactly the
same. They all have the same amount of TRBs on the
ring, they all treat the ring as an actual ring with
a link TRB pointing to the head, etc.
We're also helping the host side burst (on
SuperSpeed GEN1 or GEN2 at least) for as long as
possible until the endpoint returns NRDY.
Other than this big TRB ring rework on dwc3, we also
have a dwc3-omap DMA initialization fix, some extra
debugfs files to aid in some odd debug sessions and
a complete removal of our FIFO resizing logic.
We have a new quirk for some dwc3 P3 quirk in some
implementations.
The rest is basically non-critical fixes and the
usual cleanups.

The DWC3 OMAP driver 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-omap.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.

This patch fixes a bug where removing dwc3-omap.ko
would not trigger removal of dwc3.ko.
of_platform_depopulate() already bakes an easy to
use API for removing all our children which were
populated during probe(); Let's use that one instead
of cooking our own solution.
Note that this is kind of a revert of commit c5a1fbc
(usb: dwc3: dwc3-omap: Fix the crash on module removal)
although we can't simply revert that because a direct
call to platform_device_unregister would also be flakey.

In the wrapper the IRQ disable should be done by writing 1's to the
IRQ*_CLR register. Existing code is broken because it instead writes
zeros to IRQ*_SET register.
Fix this by adding functions dwc3_omap_write_irqmisc_clr() and
dwc3_omap_write_irq0_clr() which do the right thing.

Enabling the core interrupts in complete is too late for
XHCI, and stops it from proper operation. The root of the
problem is due to a disagreement between dwc3-omap and XHCI
about when IRQs should be enabled.
As it turns out, ->resume's documentation states that:
"... generally the driver is expected to start working
again, responding to hardware events and software requests
(the device itself may be left in a low-power state, waiting
for a runtime resume to occur) ..."
From that we infer that IRQs must be unmasked by the end of
->resume().
Due to that, we will remove ->prepare() and ->complete() and
disable/enable interrupts in ->suspend()/->resume().

This reverts commit 02dae36aa649a66c5c6181157ddd806e7b4913fc.
That commit is bogus in two ways:
1) There's no way dwc3-omap's ->suspend() can cause any effect
on xhci's ->suspend(). Linux device driver model guarantees
that a parent's ->suspend() will only be called after all
children are suspended. dwc3-omap is the parent of the
parent of xhci.
2) When implementing Deep Sleep states where context is lost,
USBOTGSS_IRQ0 register, well, looses context so we
_must_ rewrite it otherwise core IRQs will never be
reenabled and USB will appear to be dead.

the lock was only taken inside the hardirq
handler, which runs with IRQs disabled. There's
no chance of any race condition happening, even
on SMP machines. It's safe to remove that
spinlock.

Due to inter dependencies of I2C and extcon by the time dwc3
checks for extcon device its not registered especially in case of J6.
In O5 the vbus regulator save us from getting to this point.
So for tiime being return PROBE_DEFER if extcon is enabled in dt.
