When multiple DWC3 controllers are being used, trace events from

there's no way to distinguish which instance generated the trace.
Use the register base address of dwc3 controller and append it to

The COREPLL_PWRDN bit in the BLCG register must be set when the XUSB
device controller is powergated and cleared when it is unpowergated.
If this bit is not explicitly controlled, the core PLL may remain in an
incorrect power state across suspend/resume or ELPG transitions.
Therefore, update the driver to explicitly control this bit during
powergate transitions.

If the ucsi port driver supports modes selection, it should implement
`add_partner_altmodes` and `remove_partner_altmodes` ucsi operations. With
these operations the driver can manage the mode selection process.
Once partner altmodes are registered, `add_partner_altmodes` is called to
start the mode selection. When the partner is unregistered,
`remove_partner_altmodes` is supposed to stop any ongoing processes and
clean up the resources.
`typec_altmode_state_update` informes mode selection about the current mode
of the Type-C connector.

The port driver sets this bit for an alternate mode description to indicate
support for the mode selection feature. Once set, individual Alt Mode
drivers will no longer attempt to activate their respective modes within
their probe functions. This prevents race conditions and non-prioritized
activation.
The bit is not set by default. If left unset, the system retains the
current behavior where Alt Mode drivers manage their own activation logic.

The mode selection process is controlled by the following API functions,
which allow to initiate and complete mode entry based on the priority of
each mode:
`typec_mode_selection_start` function compiles a priority list of supported
Alternate Modes.
`typec_altmode_state_update` function is invoked by the port driver to
communicate the current mode of the Type-C connector.
`typec_mode_selection_delete` function stops the currently running mode
selection process and releases all associated system resources.
`mode_selection_work_fn` task attempts to activate modes. The process stops
on success; otherwise, it proceeds to the next mode after a timeout or
error.

to see if a clock is optional or not. Use devm_clk_get_optional()

either a valid clock pointer or NULL, and all clock operations handle
NULL pointers gracefully, several IS_ERR() checks can be removed,

platform_get_irq(), which returns a Linux virtual IRQ number directly
managed by the device core, not by the OF subsystem. Therefore, the

soundwire: bus: fix off-by-one when allocating slave IDs
Here are some small USB fixes and new device ids for 6.19-rc6
Included in here are:
- new usb-serial device ids
- dwc3-apple driver fixes to get things working properly on that
hardware platform
- ohci/uhci platfrom driver module soft-deps with ehci to remove a
runtime warning that sometimes shows up on some platforms.
- quirk for broken devices that can not handle reading the BOS
descriptor from them without going crazy.
- usb-serial driver fixes
- xhci driver fixes
- usb gadget driver fixes
All of these except for the last xhci fix has been in linux-next for a
while. The xhci fix has been reported by others to solve the issue for
them, so should be ok.

Commit 962e8a01ea ("ext4: introduce mext_move_extent()") attempts to
call ext4_swap_extents() on the failure path to recover the swapped
extents, but fails to acquire locks for the two inode->i_data_sem,
triggering the BUG_ON statement in ext4_swap_extents().
This issue can be fixed by calling ext4_double_down_write_data_sem()
before ext4_swap_extents().

The padding at the end of struct ext4_tune_sb_params is architecture
specific and in particular is different between x86-32 and x86-64,
since the __u64 member only enforces struct alignment on the latter.
This shows up as a new warning when test-building the headers with
-Wpadded:
include/linux/ext4.h:144:1: error: padding struct size to alignment boundary with 4 bytes [-Werror=padded]
All members inside the structure are naturally aligned, so the only
difference here is the amount of padding at the end. Make the padding
explicit, to have a consistent sizeof(struct ext4_tune_sb_params) of
232 on all architectures and avoid adding compat ioctl handling for
EXT4_IOC_GET_TUNE_SB_PARAM/EXT4_IOC_SET_TUNE_SB_PARAM.
This is an ABI break on x86-32 but hopefully this can go into 6.18.y early
enough as a fixup so no actual users will be affected. Alternatively, the
kernel could handle the ioctl commands for both sizes (232 and 228 bytes)
on all architectures.
