When usb_submit_urb() fails in usbio_probe(), the previously allocated
URB is never freed, causing a memory leak.
Fix this by jumping to err_free_urb label to properly release the URB

The driver saves the minor number it gets upon registration
in its descriptor for debugging purposes. However, there is
inevitably a window between registration and saving the correct

Add a regulator-only entry matching OF-described USB Type-A connectors.
This allows platforms to explicitly model VBUS supply regulators for these
ports instead of calling them PHY supplies or making the respective
regulators always-on in their device trees.
Type-A ports won't typically need a dedicated driver, as there is nothing
to configure apart from the power supply, so there is no controller driver
to traverse the OF graph and request the VBUS regulator, unlike for Type-C
ports. Thus make it an onboard USB device, which it kind of really is.

This was done entirely with mindless brute force, using
git grep -l '\<k[vmz]*alloc_objs*(.*, GFP_KERNEL)' |
xargs sed -i 's/\(alloc_objs*(.*\), GFP_KERNEL)/\1)/'
to convert the new alloc_obj() users that had a simple GFP_KERNEL
argument to just drop that argument.
Note that due to the extreme simplicity of the scripting, any slightly
more complex cases spread over multiple lines would not be triggered:
they definitely exist, but this covers the vast bulk of the cases, and
the resulting diff is also then easier to check automatically.
For the same reason the 'flex' versions will be done as a separate

This is the result of running the Coccinelle script from
scripts/coccinelle/api/kmalloc_objs.cocci. The script is designed to
avoid scalar types (which need careful case-by-case checking), and
instead replace kmalloc-family calls that allocate struct or union
object instances:
Single allocations: kmalloc(sizeof(TYPE), ...)
are replaced with: kmalloc_obj(TYPE, ...)
Array allocations: kmalloc_array(COUNT, sizeof(TYPE), ...)
are replaced with: kmalloc_objs(TYPE, COUNT, ...)
Flex array allocations: kmalloc(struct_size(PTR, FAM, COUNT), ...)
are replaced with: kmalloc_flex(*PTR, FAM, COUNT, ...)
(where TYPE may also be *VAR)
The resulting allocations no longer return "void *", instead returning
"TYPE *".

EUD_MODE_MANAGER2 register is mapped to a memory region that is marked
as read-only for operating system running at EL1, enforcing access
restrictions that prohibit direct memory-mapped writes via writel().
Attempts to write to this region from HLOS can result in silent failures
or memory access violations, particularly when toggling EUD (Embedded
USB Debugger) state. To ensure secure register access, modify the driver
to use qcom_scm_io_writel(), which routes the write operation to Qualcomm
Secure Channel Monitor (SCM). SCM has the necessary permissions to access
protected memory regions, enabling reliable control over EUD state.
SC7280, the only user of EUD is also affected, indicating that this could
never have worked on a properly fused device.

When multiple Apple devices are connected concurrently, the
apple-mfi-fastcharge driver fails to probe the subsequent devices with
the following error:
sysfs: cannot create duplicate filename '/class/power_supply/apple_mfi_fastcharge'
apple-mfi-fastcharge 5-2.4.3.3: probe of 5-2.4.3.3 failed with error -17
This happens because the driver uses a fixed power supply name
("apple_mfi_fastcharge") for all devices, causing a sysfs name
conflict when a second device is connected.
Fix this by generating unique names using the USB bus and device
number (e.g., "apple_mfi_fastcharge_5-12"). This ensures each
connected device gets a unique power supply entry in sysfs.
The change requires storing a copy of the power_supply_desc structure
in the per-device mfi_device struct, since the name pointer needs to
remain valid for the lifetime of the power supply registration.

record for the most number of patch series (30+) over the longest
period of time (2+ years) to get merged properly. Many props go to
Wesley Cheng for seeing this effort through, they took a major
out-of-tree hacked-up-monstrosity that was created by multiple
vendors for their specific devices, got it all merged into a
semi-coherent set of changes, and got all of the different major
subsystems to agree on how this should be implemented both with
changes to their code as well as userspace apis, AND wrangled the
hardware companies into agreeing to go forward with this, despite
making them all redo work they had already done in their private
device trees. This feature offers major power savings on embedded
devices where a USB audio stream can continue to flow while the rest
of the system is sleeping, something that devices running on battery
power really care about. There are still some more small tweaks
left to be done here, and those patches are still out for review and
arguing among the different hardware companies, but this is a major
step forward and a great example of how to do upstream development
well.
- small number of thunderbolt fixes and updates, things seem to be
slowing down here (famous last words...)
- xhci refactors and reworking to try to handle some rough corner
cases in some hardware implementations where things don't always
work properly
- typec driver updates
- USB3 power management reworking and updates
- Removal of some old and orphaned UDC gadget drivers that had not
been used in a very long time, dropping over 11 thousand lines from

Merge tag 'timers-cleanups-2025-05-25' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull timer cleanups from Thomas Gleixner:
"Another set of timer API cleanups:
- Convert init_timer*(), try_to_del_timer_sync() and
destroy_timer_on_stack() over to the canonical timer_*()
namespace convention.
There is another large conversion pending, which has not been included
because it would have caused a gazillion of merge conflicts in next.
The conversion scripts will be run towards the end of the merge window
and a pull request sent once all conflict dependencies have been
merged"

When the USB5744 option is disabled, the onboard_usb driver warns about
unused functions:
drivers/usb/misc/onboard_usb_dev.c:358:12: error: 'onboard_dev_5744_i2c_write_byte' defined but not used [-Werror=unused-function]
358 | static int onboard_dev_5744_i2c_write_byte(struct i2c_client *client, u16 addr, u8 data)
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
drivers/usb/misc/onboard_usb_dev.c:313:12: error: 'onboard_dev_5744_i2c_read_byte' defined but not used [-Werror=unused-function]
313 | static int onboard_dev_5744_i2c_read_byte(struct i2c_client *client, u16 addr, u8 *data)
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Extend the #ifdef block a little further to cover all of these functions.
Ideally we'd use use if(IS_ENABLED()) instead, but that doesn't currently
work because the i2c_transfer() and i2c_smbus_write_word_data() function
declarations are hidden when CONFIG_I2C is disabled.

Introduce i2c APIs to read/write for proper configuration register
programming. It ensures that read-modify-write sequence is performed
and reserved bit in Runtime Flags 2 register are not touched.
Also legacy smbus block write inserted an extra count value into the
i2c data stream which breaks the register write on the usb5744.
Switching to new read/write i2c APIs fixes both issues.

The TUSB8044 is similar to the TUSB8041. This adds the PID/VID values
and allows to specify the reset GPIO signal on the board.

The Cypress HX3 USB3.0 hubs use different PID values depending
on the product variant. The comment in compatibles table is
misleading, as the currently used PIDs (0x6504 and 0x6506 for
USB 3.0 and USB 2.0, respectively) are defaults for the CYUSB331x,
while CYUSB330x and CYUSB332x variants use different values.
Based on the datasheet [1], update the compatible usb devices table
to handle different types of the hub.
The change also includes vendor mode PIDs, which are used by the
hub in I2C Master boot mode, if connected EEPROM contains invalid
signature or is blank. This allows to correctly boot the hub even
if the EEPROM will have broken content.
Number of vcc supplies and timing requirements are the same for all
HX variants, so the platform driver's match table does not have to
be extended.

Parade PS5511 is 4+1 port USB 3.2 gen 1 hub with a reset pin and two power
supplies (3V3 and 1V1).
Add the support for this hub for the reset pin control and power supply.

Realtek RTL8188ETV 2.4 GHz WiFi modules (detected as RTL8188EU by the
RTL8XXXXU driver) are found soldered into some embedded devices, such as
the Fernsehfee 3.0 set-top box.
They require a 3.3V power supply.
