d19c64b3d0 thunderbolt: Changes for v5.8 merge window
This adds support for Intel Tiger Lake Thunderbolt controller using
 firmware based connection manager. In addition the driver can now be
 built on non-x86 architectures as well. Then there are a couple of
 commits that make the driver work across kexec, replace a zero length
 array with flexible one, and revert one change that is not needed
 anymore because of NVMem subsystem improvements.

fce2bc254a Simplify EFI handover to decompressor
The EFI stub in the ARM kernel runs in the context of the firmware, which
 means it usually runs with the caches and MMU on. Currently, we relocate
 the zImage so it appears in the first 128 MiB, disable the MMU and caches
 and invoke the decompressor via its ordinary entry point. However, since we
 can pass the base of DRAM directly, there is no need to relocate the zImage,
 which also means there is no need to disable and re-enable the caches and
 create new page tables etc.
 
 This also allows systems whose DRAM start address is not a round multiple
 of 128 MB to decompress the kernel proper to the base of memory, ensuring
 that all memory is usable at runtime.

12e5bf757a mfd: max77620: Use single-byte writes on MAX77620
The MAX77620 doesn't support bulk writes, so make sure the regmap code
breaks bulk writes into multiple single-byte writes.

Note that this is mostly cosmetic because currently only the RTC sub-
driver uses bulk writes and the RTC driver ends up using a different
regmap on the MAX77620 anyway. However, it seems like a good idea to
make this change now in order to avoid running into issues if bulk
writes are ever used by other sub-drivers sometime down the road.

f4a1954036 mfd: wm8994: Fix unbalanced calls to regulator_bulk_disable()
When runtime PM is enabled, regulators are being controlled by the
driver's suspend and resume callbacks. They are also unconditionally
enabled at driver's probe(), and disabled in remove() functions. Add
more calls to runtime PM framework to ensure that the device's runtime
PM state matches the regulators state:
1. at the end of probe() function: set runtime PM state to active, so
there will be no spurious call to resume();
2. in remove(), ensure that resume() is called before disabling runtime PM
management and unconditionally disabling the regulators.

d4f9b5428b mfd: wm8994: Fix driver operation if loaded as modules
WM8994 chip has built-in regulators, which might be used for chip
operation. They are controlled by a separate wm8994-regulator driver,
which should be loaded before this driver calls regulator_get(), because
that driver also provides consumer-supply mapping for the them. If that
driver is not yet loaded, regulator core substitute them with dummy
regulator, what breaks chip operation, because the built-in regulators are
never enabled. Fix this by annotating this driver with MODULE_SOFTDEP()
"pre" dependency to "wm8994_regulator" module.

e72455b898 HID: sony: Fix for broken buttons on DS3 USB dongles
Fix for non-working buttons on knock-off USB dongles for Sony
controllers. These USB dongles are used to connect older Sony DA/DS1/DS2
controllers via USB and are common on Amazon, AliExpress, etc.  Without
the patch, the square, X, and circle buttons do not function.  These
dongles used to work prior to kernel 4.10 but removing the global DS3
report fixup in commit e19a267b99 ("HID: sony: DS3 comply to Linux gamepad
spec") exposed the problem.

Many people reported the problem on the Ubuntu forums and are working
around the problem by falling back to the 4.9 hid-sony driver.

The problem stems from these dongles incorrectly reporting their button
count as 13 instead of 16.  This patch fixes up the report descriptor by
changing the button report count to 16 and removing 3 padding bits.

It added a pr_debug() message which is issued when deadline timer

Well, issued only when CONFIG_DYNAMIC_DEBUG is enabled - otherwise
pr_debug() calls get optimized away if DEBUG is not defined in the

Therefore, make the above message pr_info() so that it is visible in

a871be6b8e cpuidle: Convert Qualcomm SPM driver to a generic CPUidle driver
The Qualcomm SPM cpuidle driver seems to be the last driver still
using the generic ARM CPUidle infrastructure.

Converting it actually allows us to simplify the driver,
and we end up being able to remove more lines than adding new ones:

  - We can parse the CPUidle states in the device tree directly
    with dt_idle_states (and don't need to duplicate that
    functionality into the spm driver).

  - Each "saw" device managed by the SPM driver now directly
    registers its own cpuidle driver, removing the need for
    any global (per cpu) state.

The device tree binding is the same, so the driver stays
compatible with all old device trees.

        int stuff;
        struct boo array[];
};

By making use of the mechanism above, we will get a compiler warning
in case the flexible array does not occur last in the structure, which
will help us prevent some kind of undefined behavior bugs from being
inadvertently introduced[3] to the codebase from now on.

Also, notice that, dynamic memory allocations won't be affected by
this change:

"Flexible array members have incomplete type, and so the sizeof operator
may not be applied. As a quirk of the original implementation of
zero-length arrays, sizeof evaluates to zero."[1]

sizeof(flexible-array-member) triggers a warning because flexible array
members have incomplete type[1]. There are some instances of code in
which the sizeof operator is being incorrectly/erroneously applied to
zero-length arrays and the result is zero. Such instances may be hiding
some bugs. So, this work (flexible-array member conversions) will also
help to get completely rid of those sorts of issues.

This issue was found with the help of Coccinelle.

595d153dd1 powerpc/64s: Fix restore of NV GPRs after facility unavailable exception
Commit 702f098052 ("powerpc/64s/exception: Remove lite interrupt
return") changed the interrupt return path to not restore non-volatile
registers by default, and explicitly restore them in paths where it is
required.

But it missed that the facility unavailable exception can sometimes
modify user registers, ie. when it does emulation of move from DSCR.

This is seen as a failure of the dscr_sysfs_thread_test:
  test: dscr_sysfs_thread_test
  [cpu 0] User DSCR should be 1 but is 0
  failure: dscr_sysfs_thread_test

So restore non-volatile GPRs after facility unavailable exceptions.

Currently the hypervisor facility unavailable exception is also wired
up to call facility_unavailable_exception().

In practice we should never take a hypervisor facility unavailable
exception for the DSCR. On older bare metal systems we set HFSCR_DSCR
unconditionally in __init_HFSCR, or on newer systems it should be
enabled via the "data-stream-control-register" device tree CPU
feature.

Even if it's not, since commit f3c99f97a3 ("KVM: PPC: Book3S HV:
Don't access HFSCR, LPIDR or LPCR when running nested"), the KVM code
has unconditionally set HFSCR_DSCR when running guests.

So we should only get a hypervisor facility unavailable for the DSCR
if skiboot has disabled the "data-stream-control-register" feature,
and we are somehow in guest context but not via KVM.

Given all that, it should be unnecessary to add a restore of
non-volatile GPRs after the hypervisor facility exception, because we
never expect to hit that path. But equally we may as well add the
restore, because we never expect to hit that path, and if we ever did,
at least we would correctly restore the registers to their post
emulation state.

In future we can split the non-HV and HV facility unavailable handling
so that there is no emulation in the HV handler, and then remove the
restore for the HV case.

9ad346c905 batman-adv: Revert "disable ethtool link speed detection when auto negotiation off"
The commit 8c46fcd783 ("batman-adv: disable ethtool link speed detection
when auto negotiation off") disabled the usage of ethtool's link_ksetting
when auto negotation was enabled due to invalid values when used with
tun/tap virtual net_devices. According to the patch, automatic measurements
should be used for these kind of interfaces.

But there are major flaws with this argumentation:

* automatic measurements are not implemented
* auto negotiation has nothing to do with the validity of the retrieved
  values

The first point has to be fixed by a longer patch series. The "validity"
part of the second point must be addressed in the same patch series by
dropping the usage of ethtool's link_ksetting (thus always doing automatic
measurements over ethernet).

Drop the patch again to have more default values for various net_device
types/configurations. The user can still overwrite them using the
batadv_hardif's BATADV_ATTR_THROUGHPUT_OVERRIDE.

The Asus USB DAC is a USB type-C audio dongle for connecting to
the headset and headphone. The volume minimum value -23040 which
is 0xa600 in hexadecimal with the resolution value 1 indicates
this should be endianness issue caused by the firmware bug. Add
a volume quirk to fix the volume control problem.

399c01aa49 ALSA: hda/realtek - Add a model for Thinkpad T570 without DAC workaround
We fixed the regression of the speaker volume for some Thinkpad models
(e.g. T570) by the commit 54947cd64c ("ALSA: hda/realtek - Fix
speaker output regression on Thinkpad T570").  Essentially it fixes
the DAC / pin pairing by a static table.  It was confirmed and merged
to stable kernel later.

Now, interestingly, we got another regression report for the very same
model (T570) about the similar problem, and the commit above was the
culprit.  That is, by some reason, there are devices that prefer the
DAC1, and another device DAC2!

Unfortunately those have the same ID and we have no idea what can
differentiate, in this patch, a new fixup model "tpt470-dock-fix" is
provided, so that users with such a machine can apply it manually.
When model=tpt470-dock-fix option is passed to snd-hda-intel module,
it avoids the fixed DAC pairing and the DAC1 is assigned to the
speaker like the earlier versions.
