9e2e5ea3b2 USB / Thunderbolt changes for 6.0-rc1
Here is the big set of Thunderbolt and USB changes for 6.0-rc1.
 
 Lots of little things here, nothing major, just constant development on
 some new hardware support and cleanups of older drivers.  Highlights of
 this pull request are:
 	- lots of typec changes and improvements for new hardware
 	- new gadget controller driver
 	- thunderbolt support for new hardware
 	- the normal set of new usb-serial device ids and cleanups
 	- loads of dwc3 controller fixes and improvements
 	- mtu3 driver updates
 	- testusb fixes for longtime issues (not many people use this
 	  tool it seems.)
 	- minor driver fixes and improvements over the USB tree
 	- chromeos platform driver changes were added and then reverted
 	  as they depened on some typec changes, but the cross-tree
 	  merges caused problems so they will come back later through
 	  the platform tree.
 
 All of these have been in linux-next for a while now with no reported
 issues.

d60b6b0bc0 Merge branch 'acpi-bus'
Merge ACPI device object management changes for v5.20-rc1.

 - Use the facilities provided by the driver core and some additional
   helpers to handle the children of a given ACPI device object in
   multiple places instead of using the children and node list heads in
   struct acpi_device which is error prone (Rafael Wysocki).

 - Fix ACPI-related device reference counting issue in the hisi_lpc bus
   driver (Yang Yingliang).

 - Drop the children and node list heads that are not needed any more
   from struct acpi_device (Rafael Wysocki).

 - Drop driver member from struct acpi_device (Uwe Kleine-König).

 - Drop redundant check from acpi_device_remove() (Uwe Kleine-König).

2d945194cc usb: typec: ucsi: stm32g0: add bootloader support
STM32G0 comes with STM32 bootloader in its system memory. Add support
for some I2C bootloader commands as described in application notes
AN2606 and AN4221, to enable STM32G0 UCSI firmware update.

Upon probing, the driver needs to know the STM32G0 state:
- In bootloader mode, STM32 G0 answers at i2c addr 0x51.
- In running mode, STM32 G0 firmware may answer at two address.
  - The main address specified in DT is used for UCSI.
  - 0x51 addr can be re-used for FW controls like getting software version
    or jump to booloader request.

So probe using the main firmware i2c address first, before attempting
bootloader address (e.g. check for blank, erased or previously aborted
firmware update).

72849d4fce usb: typec: ucsi: stm32g0: add support for stm32g0 controller
STM32G0 provides an integrated USB Type-C and power delivery interface.
It can be programmed with a firmware to handle UCSI protocol over I2C
interface. A GPIO is used as an interrupt line.

Type-C connector can be used as a wakeup source (typically to detect
changes on the port, like attach or detach). PM suspend / resume routines
are used to enable wake irqs, and signal a wakeup event in case the IRQ
has fired while in suspend. The i2c core is doing the necessary
initialization when the "wakeup-source" flag is provided.
Note: the interrupt handler shouldn't be called before the i2c bus resumes.
So, the interrupts are disabled during suspend period, and re-enabled
upon resume, to avoid i2c transfer while suspended, from the irq handler.

0c34043897 usb: typec: retimer: Add missing id check in match callback
The fwnode_connection_find_match() function handles two cases: named
references and graph endpoints. In the second case, the match function
passed in is called with the id to check for the match. However, the
match function for the recently added type-c retimer class assumes the
connection has already been matched (which is only true for the first
case).

The result is that with that change, all type-c nodes with graph
endpoints defer probe indefinitely, independently of having a retimer
connection or not.

Add the missing check, like is done by the type-c mux and usb role
switch code, to fix the issue.

The bug occurs because usb_udc_uevent() dereferences udc->driver but
does so without acquiring the udc_lock mutex, which protects this
field.  If the gadget driver is unbound from the udc concurrently with
uevent processing, the driver structure may be accessed after it has
been deallocated.

To prevent the race, we make sure that the routine holds the mutex
around the racing accesses.

26c6c2f8a9 USB: HCD: Fix URB giveback issue in tasklet function
Usb core introduce the mechanism of giveback of URB in tasklet context to
reduce hardware interrupt handling time. On some test situation(such as
FIO with 4KB block size), when tasklet callback function called to
giveback URB, interrupt handler add URB node to the bh->head list also.
If check bh->head list again after finish all URB giveback of local_list,
then it may introduce a "dynamic balance" between giveback URB and add URB
to bh->head list. This tasklet callback function may not exit for a long
time, which will cause other tasklet function calls to be delayed. Some
real-time applications(such as KB and Mouse) will see noticeable lag.

In order to prevent the tasklet function from occupying the cpu for a long
time at a time, new URBS will not be added to the local_list even though
the bh->head list is not empty. But also need to ensure the left URB
giveback to be processed in time, so add a member high_prio for structure
giveback_urb_bh to prioritize tasklet and schelule this tasklet again if
bh->head list is not empty.

At the same time, we are able to prioritize tasklet through structure
member high_prio. So, replace the local high_prio_bh variable with this
structure member in usb_hcd_giveback_urb.

This is a minor bug which means that certain error messages are not

requested function.  Print an error in either case.

Type C ports can be linked to retimers using firmware node device

07903626d9 usb: dwc3: core: Do not perform GCTL_CORE_SOFTRESET during bootup
According to the programming guide, it is recommended to
perform a GCTL_CORE_SOFTRESET only when switching the mode
from device to host or host to device. However, it is found
that during bootup when __dwc3_set_mode() is called for the
first time, GCTL_CORESOFTRESET is done with suspendable bit(BIT 17)
of DWC3_GUSB3PIPECTL set. This some times leads to issues
like controller going into bad state and controller registers
reading value zero. Until GCTL_CORESOFTRESET is done and
run/stop bit is set core initialization is not complete.
Setting suspendable bit of DWC3_GUSB3PIPECTL and then
performing GCTL_CORESOFTRESET is therefore not recommended.
Avoid this by only performing the reset if current_dr_role is set,
that is, when doing subsequent role switching.

220fafb4ed usb: aspeed-vhub: Fix refcount leak bug in ast_vhub_init_desc()
We should call of_node_put() for the reference returned by
of_get_child_by_name() which has increased the refcount.

efa2bebf2a usb: ldusb: replace ternary operator with max_t()
Fix the following coccicheck warning:

drivers/usb/misc/ldusb.c:719: WARNING opportunity for max().
drivers/usb/misc/ldusb.c:721: WARNING opportunity for max().

max_t() macro is defined in include/linux/minmax.h. It avoids
multiple evaluations of the arguments when non-constant and performs
strict type-checking.

5e76ee96be usb: dwc3: ep0: Properly handle setup_packet_pending scenario in data stage
During a 3 stage SETUP transfer, if the host sends another SETUP token
before completing the status phase, it signifies that the host has aborted
the current control transfer.  Currently, if a setup_packet_pending is
received, there are no subsequent calls to dwc3_ep0_out_start() to fetch
the new SETUP packet.  This leads to a stall on EP0, as host does not
expect another STATUS phase as it has aborted the current transfer.

Fix this issue by explicitly stalling and restarting EP0, as well as
resetting the trb_enqueue indexes.  (without this, there is a chance the
SETUP TRB is set up on trb_endqueue == 1)
