Introduce a driver to configure USB Type-C mode switches and retimers
which are controlled by the Chrome OS EC (Embedded Controller).
This allows Type-C port drivers, as well as alternate mode drivers to
configure their relevant mode switches and retimers according to the
Type-C state they want to achieve.
ACPI devices with ID GOOG001A will bind to this driver.
Currently, we only register a retimer switch with a stub set function.
Subsequent patches will implement the host command set functionality,
and introduce mode switches.

Copy EC header definitions for the USB Type-C Mux control command from
the EC code base. Also pull in "TBT_UFP_REPLY" definitions, since that
is the prior entry in the enum.
These headers are already present in the EC code base. [1]

Instead of doing complicated calculations to find the size of the subroutines
(which are even more complicated because they need to be stringified into
an asm statement), just hardcode to 16.
It is less dense for a few combinations of IBT/SLS/retbleed, but it has
the advantage of being really simple.

The console_stop() and console_start() functions call pr_flush().
When suspending, these functions are called by the serial subsystem
while the serial port is suspended. In this scenario, if there are
any pending messages, a call to pr_flush() will always result in a
timeout because the serial port cannot make forward progress. This
causes longer suspend and resume times.
Add a check in pr_flush() so that it will immediately timeout if
the consoles are suspended.
Fixes: 3b604ca81202 ("printk: add pr_flush()")

Building with UBSAN_DIV_ZERO with clang produces numerous fallthrough
warnings from objtool.
In the case of uncheck division, UBSAN_DIV_ZERO may introduce new
control flow to check for division by zero.
Because the result of the division is undefined, LLVM may optimize the
control flow such that after the call to __ubsan_handle_divrem_overflow
doesn't matter. If panic_on_warn was set,
__ubsan_handle_divrem_overflow would panic.
The problem is is that panic_on_warn is run time configurable. If it's
disabled, then we cannot guarantee that we will be able to recover
safely. Disable this config for clang until we can come up with a
solution in LLVM.

This reverts commit 4a57a8400075bc5287c5c877702c68aeae2a033d.
Dave Chinner reports:
"As I suspected would occur, this change causes test failures. e.g
generic/517 in fstests fails with:
generic/517 1s ... - output mismatch [..]
-deduped 131172/131172 bytes at offset 65536
+deduped 131072/131172 bytes at offset 65536"
can you please revert this commit for the 5.19 series to give us more
time to investigate and consider the impact of the the API change on
userspace applications before we commit to changing the API"
That changed return value seems to reflect reality, but with the fstest
change, let's revert for now.

Pull networking fixes from Jakub Kicinski:
"Including fixes from netfilter, bpf and wireless.
Still no major regressions, the release continues to be calm. An
uptick of fixes this time around due to trivial data race fixes and
patches flowing down from subtrees.
There has been a few driver fixes (particularly a few fixes for false
positives due to 66e4c8d95008 which went into -next in May!) that make
me worry the wide testing is not exactly fully through.

- Lag, decouple FDB selection and shared FDB
- Lag, correct get the port select mode str
- bnxt_en: fix and simplify XDP transmit path

Previous releases - regressions:
- conntrack: fix crash due to confirmed bit load reordering (after
atomic -> refcount conversion)
- stmmac: dwc-qos: disable split header for Tegra194
Previous releases - always broken:
- mlx5e: ring the TX doorbell on DMA errors
- bpf: make sure mac_header was set before using it
- mac80211: do not wake queues on a vif that is being stopped
- mac80211: fix queue selection for mesh/OCB interfaces

Commit 3a0cf7ab8df3 ("ACPI: video: Change how we determine if brightness
key-presses are handled") made acpi_video_handles_brightness_key_presses()
report false when none of the ACPI Video Devices support backlight control.
But it turns out that at least on a Dell Inspiron N4010 there is no ACPI
backlight control, yet brightness hotkeys are still reported through
the ACPI Video Bus; and since acpi_video_handles_brightness_key_presses()
now returns false, brightness keypresses are now reported twice.
To fix this rename the has_backlight flag to may_report_brightness_keys and
also set it the first time a brightness key press event is received.
Depending on the delivery of the other ACPI (WMI) event vs the ACPI Video
Bus event this means that the first brightness key press might still get
reported twice, but all further keypresses will be filtered as before.
Note that this relies on other drivers reporting brightness key events
calling acpi_video_handles_brightness_key_presses() when delivering
the events (rather then once during driver probe). This is already
required and documented in include/acpi/video.h:
/*
* Note: The value returned by acpi_video_handles_brightness_key_presses()
* may change over time and should not be cached.
*/

The UML function names to_virt() and to_phys() are exposed by UML
headers, and are very generic and may be defined by drivers. As it
turns out, commit 9409c9b6709e ("pmem: refactor pmem_clear_poison()")
did exactly that.
This results in build errors such as the following when trying to build
um:allmodconfig:
drivers/nvdimm/pmem.c: In function ‘pmem_dax_zero_page_range’:
./arch/um/include/asm/page.h:105:20: error: too few arguments to function ‘to_phys’
105 | #define __pa(virt) to_phys((void *) (unsigned long) (virt))
| ^~~~~~~
Use less generic function names for the um specific to_phys() and
to_virt() functions to fix the problem and to avoid similar problems in
the future.

The DRM_AMD_DC_DCN display engine support (Raven, Navi, and newer) has
not been building cleanly on powerpc and causes link errors due to
mixing hard- and soft-float object files:
powerpc64-linux-ld: drivers/gpu/drm/amd/amdgpu/../display/dc/dml/display_mode_lib.o uses hard float, drivers/gpu/drm/amd/amdgpu/../display/dc/dcn31/dcn31_resource.o uses soft float
powerpc64-linux-ld: failed to merge target specific data of file drivers/gpu/drm/amd/amdgpu/../display/dc/dcn31/dcn31_resource.o
[..]
and while patches are floating around, it's not exactly obvious what is
going on.
The problem bisects to commit 41b7a347bf14 ("powerpc: Book3S 64-bit
outline-only KASAN support") but that is probably more about changing
config variables than the fundamental cause.
Despite the bisection result, a more directly related commit seems to be
26f4712aedbd ("drm/amd/display: move FPU related code from dcn31 to
dml/dcn31 folder"). It's probably a combination of the two.
This has been going on since the merge window, without any final word.
So instead of blindly applying patches that may or may not be the right
thing, let's disable this for now.
As Michael Ellerman says:
"IIUIC this code was never enabled on ppc before, so disabling it seems
like a reasonable fix to get the build clean"
and once we have more actual feedback (and find any potential users) we
can always re-enable it with the patch that fixes the issues and
back-port as necessary.

The commit 513616843d73 ("block: remove superfluous calls to

__bio_clone since submit_bio will override ->bi_issue.
However, __blk_queue_split is called after blkcg_bio_issue_init
(see blk_mq_submit_bio) in submit_bio. In this case, the
->bi_issue is 0. Fix it.

The issue exists when multipath is enabled and the namespace is
shared, but all the other controller checks at nvme_is_unique_nsid()
are false. The reason for this issue is that nvme_is_unique_nsid()
returns false when is called from nvme_mpath_alloc_disk() due to an
uninitialized value of head->shared. The patch fixes it by setting
head->shared before nvme_mpath_alloc_disk() is called.

Introduce a retimer device class and associated functions that register
and use retimer "switch" devices. These operate in a manner similar to
the "mode-switch" and help configure retimers that exist between the
Type-C connector and host controller(s).
Type C ports can be linked to retimers using firmware node device
references (again, in a manner similar to "mode-switch").
There are no new sysfs files being created; there is the new retimer
class directory, but there are no class-specific files being created
there.

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.

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)

This reverts commit ebc4969ae125e65fdb563f66f4bfa7aec95f7eb4. That
commit was supposed to make the binding better reflect the MediaTek XHCI
hardware block by requiring all clocks to be present. But doing that
also causes too much noise in the devicetrees, since it requires
updating old MediaTek DTs to add clock handles for the fixed clocks, and
going forward every new clock added to the binding would require even
more updates.
The commit also didn't update the example to match the changes, causing
additional warnings.
Instead let's keep the clocks optional so that old devicetrees can keep
omitting the fixed clocks, and we'll just add the clocks as required on
new DTs.

It allows to reset prevent_medium_removal flag and "eject" the image.
This can be useful to free the drive from a hunging host or if the host
continues to use the drive even after unmounting (Linux does this).
It's also a bit like using an unfolded paperclip on an optical drive.
Previously, the undocumented method of sending SIGUSR1 to a special
"file-storage" kernel thread could be used for these purposes,
but when using multiple storages there was no way to distinguish
one from the other, so we had to send a signal to everyone.
