45d39448b4 usb: dwc3: support 64 bit DMA in platform driver
Currently, the dwc3 platform driver does not explicitly ask for
a DMA mask. This makes it fall back to the default 32-bit mask which
breaks the driver on systems that only have RAM starting above the
first 4G like the Apple M1 SoC.

Fix this by calling dma_set_mask_and_coherent with a 64bit mask.

60dfe484ce USB: core: Avoid WARNings for 0-length descriptor requests
The USB core has utility routines to retrieve various types of
descriptors.  These routines will now provoke a WARN if they are asked
to retrieve 0 bytes (USB "receive" requests must not have zero
length), so avert this by checking the size argument at the start.

remove debugfs for its endpoints, it meets NULL pointer dereference

This patch adds a udc_async_callbacks handler to the net2272 UDC
driver, which will prevent a theoretical race during gadget unbinding.

The net2272 driver is sufficiently complicated that I didn't want to

04145a03db USB: UDC: Implement udc_async_callbacks in dummy-hcd
This patch adds a udc_async_callbacks handler to the dummy-hcd UDC
driver, which will prevent a theoretical race during gadget unbinding.

The implementation is simple, since dummy-hcd already has a flag to
keep track of whether emulated IRQs are enabled.  All the handler has
to do is store the enable value in the flag, and avoid setting the
flag prematurely.

7dc0c55e9f USB: UDC core: Add udc_async_callbacks gadget op
The Gadget API has a theoretical race when a gadget driver is unbound.
Although the pull-up is turned off before the driver's ->unbind
callback runs, if the USB cable were to be unplugged at just the wrong
moment there would be nothing to prevent the UDC driver from invoking
the ->disconnect callback after the unbind has finished.  In theory,
other asynchronous callbacks could also happen during the time before
the UDC driver's udc_stop routine is called, and the gadget driver
would not be prepared to handle any of them.

We need a way to tell UDC drivers to stop issuing asynchronous (that is,
->suspend, ->resume, ->disconnect, ->reset, or ->setup) callbacks at
some point after the pull-up has been turned off and before the
->unbind callback runs.  This patch adds a new ->udc_async_callbacks
callback to the usb_gadget_ops structure for precisely this purpose,
and it adds the corresponding support to the UDC core.

Later patches in this series add support for udc_async_callbacks to
several UDC drivers.

The USB charger type and status was already propagated to userspace
through kobject_uevent_env during charger notify work. Nevertheless the
uevent could be lost e.g. because it could be fired at an early kernel
boot stage, way before udev daemon or any other user-space app was able
to catch it. Registering uevent hook for introduced usb_phy_dev_type
will allow to query sysfs 'uevent' file to restore that information at

5ff90af9da usb: dwc3: debugfs: Add and remove endpoint dirs dynamically
The DWC3 DebugFS directory and files are currently created once
during probe.  This includes creation of subdirectories for each
of the gadget's endpoints.  This works fine for peripheral-only
controllers, as dwc3_core_init_mode() calls dwc3_gadget_init()
just prior to calling dwc3_debugfs_init().

However, for dual-role controllers, dwc3_core_init_mode() will
instead call dwc3_drd_init() which is problematic in a few ways.
First, the initial state must be determined, then dwc3_set_mode()
will have to schedule drd_work and by then dwc3_debugfs_init()
could have already been invoked.  Even if the initial mode is
peripheral, dwc3_gadget_init() happens after the DebugFS files
are created, and worse so if the initial state is host and the
controller switches to peripheral much later.  And secondly,
even if the gadget endpoints' debug entries were successfully
created, if the controller exits peripheral mode, its dwc3_eps
are freed so the debug files would now hold stale references.

So it is best if the DebugFS endpoint entries are created and
removed dynamically at the same time the underlying dwc3_eps are.
Do this by calling dwc3_debugfs_create_endpoint_dir() as each
endpoint is created, and conversely remove the DebugFS entry when
the endpoint is freed.

This reverts commit acad3e9c72.

The device property that can be used to identify the device
class/type of the remote port parent when device graph is
used is always needed after all. Without it there is no real
way to know is the requested connection actually described
in the device graph or not.

If the connection is described in the device graph but the
device instance is still missing for what ever reason, the
code defers probe for now.

Adding a comment to the code to explain this.

7652dd2c5c USB: core: Check buffer length matches wLength for control transfers
A type of inconsistency that can show up in control URBs is when the
setup packet's wLength value does not match the URB's
transfer_buffer_length field.  The two should always be equal;
differences could lead to information leaks or undefined behavior for
OUT transfers or overruns for IN transfers.

This patch adds a test for such mismatches during URB submission.  If
the test fails, the submission is rejected with a -EBADR error code
(which is not used elsewhere in the USB core), and a debugging message
is logged for people interested in tracking down these errors.

70f400d4d9 driver core: Move the "removable" attribute from USB to core
Move the "removable" attribute from USB to core in order to allow it to be
supported by other subsystem / buses. Individual buses that want to support
this attribute can populate the removable property of the device while
enumerating it with the 3 possible values -
 - "unknown"
 - "fixed"
 - "removable"
Leaving the field unchanged (i.e. "not supported") would mean that the
attribute would not show up in sysfs for that device. The UAPI (location,
symantics etc) for the attribute remains unchanged.

Move the "removable" attribute from USB to the device core so it can be
used by other subsystems / buses.

By default, devices do not have a "removable" attribute in sysfs.

If a subsystem or bus driver wants to support a "removable" attribute, it
should call device_set_removable() before calling device_register() or
device_add(), e.g.:

    device_set_removable(dev, DEVICE_REMOVABLE);
    device_register(dev);

The possible values and the resulting sysfs attribute contents are:

    DEVICE_REMOVABLE_UNKNOWN  ->  "unknown"
    DEVICE_REMOVABLE          ->  "removable"
    DEVICE_FIXED              ->  "fixed"

Convert the USB "removable" attribute to use this new device core
functionality.  There should be no user-visible change in the location or
semantics of attribute for USB devices.

ab00a41e73 usb: dwc3: trace: Remove unused fields in dwc3_log_trb
Commit 0bd0f6d201 ("usb: dwc3: gadget: remove allocated/queued request
tracking") removed the allocated & queued fields from struct dwc3_ep
but neglected to also remove them from the dwc3_log_trb event class's
TP_STRUCT definition which are now unused. Remove them to save eight
bytes per trace event entry.

acad3e9c72 usb: typec: mux: Remove requirement for the "orientation-switch" device property
The additional boolean device property "orientation-switch"
is not needed when the connection is described with device
graph, so removing the check and the requirement for it.

7bf991eab8 usb: typec: mux: Use device type instead of device name for matching
Both the USB Type-C switch and mux have already a device
type defined for them. We can use those types instead of the
device name to differentiate the two.
