For devm_usb_put_phy(), its comment says it needs to invoke usb_put_phy()
to release the phy, but it does not do that actually, so it can not fully
undo what the API devm_usb_get_phy() does, that is wrong, fixed by using
devres_release() instead of devres_destroy() within the API.

After commit 0edb555a65d1 ("platform: Make platform_driver::remove()
return void") .remove() is (again) the right callback to implement for
platform drivers.
Convert all platform drivers below drivers/usb to use .remove(), with
the eventual goal to drop struct platform_driver::remove_new(). As
.remove() and .remove_new() have the same prototypes, conversion is done
by just changing the structure member name in the driver initializer.

i2c_device_id::driver_data to 0
These drivers don't use the driver_data member of struct i2c_device_id,
so don't explicitly initialize this member.
This prepares putting driver_data in an anonymous union which requires
either no initialization or named designators. But it's also a nice
cleanup on its own.

1p1 is off when the system enters suspend at i.MX6UL. It cause the PHY
get wrong USB DP/DM value, then unexpected wakeup may occur if USB wakeup
enabled. This will enable weak 1p1 during PHY suspend if vbus exist. So
USB DP/DM is correct when system suspend.

Some USB controller drivers call otg_set_vbus when entering host or
device mode. Implement this callback so that VBUS can be turned on and
off automatically. This is especially useful when there is no property
for a VBUS supply in the controller's binding.
This results in a change in semantics of the vbus_draw regulator.
Whereas before it represented the VBUS supplied by an A-Device when we
acted as a B-Device, now it represents an internal VBUS source.
Accordingly, we no longer set the current limit or enable/disable the
bus from nop_gpio_vbus_thread. Because this supply was never initialized
before the previous commit, there should be no change in behavior.

When CONFIG_USB_OTG is not set, mxs_phy_is_otg_host() will always return

for either host or device mode. Therefore, CONFIG_USB_OTG condition
can be removed.

sysfs_emit()
Since snprintf() has the documented, but still rather strange trait of
returning the length of the data that *would have been* written to the
array if space were available, rather than the arguably more useful
length of data *actually* written, it is usually considered wise to use
something else instead in order to avoid confusion.
In the case of sysfs call-backs, new wrappers exist that do just that.

The function mxs_phy_is_otg_host() will return true if OTG_ID_VALUE is
0 at USBPHY_CTRL register. However, OTG_ID_VALUE will not reflect the real
state if the ID pin is float, such as Host-only or Type-C cases. The value
of OTG_ID_VALUE is always 1 which means device mode.
This patch will fix the issue by judging the current mode based on
last_event. The controller will update last_event in time.

The DT of_device.h and of_platform.h date back to the separate
of_platform_bus_type before it as merged into the regular platform bus.
As part of that merge prepping Arm DT support 13 years ago, they
"temporarily" include each other. They also include platform_device.h
and of.h. As a result, there's a pretty much random mix of those include
files used throughout the tree. In order to detangle these headers and
replace the implicit includes with struct declarations, users need to
explicitly include the correct includes.

- fw_devlink fixes and updates. This has gone through numerous review
cycles and lots of review and testing by lots of different devices.
Hopefully all should be good now, and Saravana will be keeping a
watch for any potential regression on odd embedded systems.
- driver core changes to work to make struct bus_type able to be
moved into read-only memory (i.e. const) The recent work with Rust
has pointed out a number of areas in the driver core where we are
passing around and working with structures that really do not have
to be dynamic at all, and they should be able to be read-only
making things safer overall. This is the contuation of that work
(started last release with kobject changes) in moving struct
bus_type to be constant. We didn't quite make it for this release,
but the remaining patches will be finished up for the release after
this one, but the groundwork has been laid for this effort.
Other than that we have in here:
- debugfs memory leak fixes in some subsystems
- error path cleanups and fixes for some never-able-to-be-hit
codepaths.
- cacheinfo rework and fixes
- Other tiny fixes, full details are in the shortlog
All of these have been in linux-next for a while with no reported
problems"
[ Geert Uytterhoeven points out that that last sentence isn't true, and
that there's a pending report that has a fix that is queued up - Linus ]

The uevent() callback in struct device_type should not be modifying the
device that is passed into it, so mark it as a const * and propagate the
function signature changes out into all relevant subsystems that use
this callback.

With the H2 and H3 board support removed from the driver, there
are actually no other users, so the entire driver can go away.

After the removal of the unused board files, I went through the
omap1 code to look for code that no longer has any callers
and remove that.
In particular, support for the omap7xx/omap8xx family is now
completely unused, so I'm only leaving omap15xx/omap16xx/omap59xx.

Make it possible to probe the GPIO VBUS detection driver
from the device tree compatible for GPIO USB B connectors.
Since this driver is using the "gpio-usb-b-connector"
compatible, it is important to discern it from the role
switch connector driver (which does not provide a phy),
so we add some Kconfig text and depend on !USB_CONN_GPIO.

phy-generic uses the existance of the property "vcc-supply" to see if a
regulator is optional or not. Use devm_regulator_get_optional() instead
which exists for this purpose. Using devm_regulator_get_optional()
avoids "supply vcc not found, using dummy regulator" messages.
