Add support for the Congatec Board Controller. This controller exposes
temperature, voltage, current and fan sensors.
The available sensors list cannot be predicted. Some sensors can be
present or not, depending the system.
The driver has an internal list of all possible sensors, for all Congatec
boards. The Board Controller gives to the driver its sensors list, and
their status (active or not).

Merge series from "Nícolas F. R. A. Prado" <nfraprado@collabora.com>:
This series enables the MT8188-MT6359 sound driver to retrieve the
MT6359 ACCDET sound component from a mediatek,accdet DT property, which
allows detecting jack insertion/removal.
Patch 1 describes the new property in the binding. Patch 2 implements
the sound component retrieval in the common MTK soundcard driver. Patch
4 updates the MT8188-MT6359 sound driver to register the audio jack and
initialize the ACCDET driver for detection, if the property is present.
Patch 3 adds a stub to prevent a linker failure in case the
MT6359-ACCDET config is disabled.
Tested on the Genio 700 EVK board.

Commit d0c94c49792c ("KVM: arm64: Restore PMU configuration on first
run") added the code to reload the PMU configuration on first run.
It is also important to keep the correct state even if system registers
are modified after first run, specifically when debugging Windows on
QEMU with GDB; QEMU tries to write back all visible registers when
resuming the VM execution with GDB, corrupting the PMU state. Windows
always uses the PMU so this can cause adverse effects on that particular
OS.
The usual register writes and reset are already handled independently,
but register writes from userspace are not covered.
Trigger the code to reload the PMU configuration for them instead so
that PMU configuration changes made by users will be applied also after
the first run.

Reload the perf event when setting the vPMU counter (vPMC) registers
(PMCCNTR_EL0 and PMEVCNTR<n>_EL0). This is a change corresponding to
commit 9228b26194d1 ("KVM: arm64: PMU: Fix GET_ONE_REG
for vPMC regs to return the current value") but for SET_ONE_REG.
Values of vPMC registers are saved in sysreg files on certain occasions.
These saved values don't represent the current values of the vPMC
registers if the perf events for the vPMCs count events after the save.
The current values of those registers are the sum of the sysreg file
value and the current perf event counter value. But, when userspace
writes those registers (using KVM_SET_ONE_REG), KVM only updates the
sysreg file value and leaves the current perf event counter value as is.
It is also important to keep the correct state even if userspace writes
them after first run, specifically when debugging Windows on QEMU with
GDB; QEMU tries to write back all visible registers when resuming the VM
execution with GDB, corrupting the PMU state. Windows always uses the
PMU so this can cause adverse effects on that particular OS.
Fix this by releasing the current perf event and trigger recreating one
with KVM_REQ_RELOAD_PMU.

Many functions in pmu-emul.c checks kvm_vcpu_has_pmu(vcpu). A favorable
interpretation is defensive programming, but it also has downsides:
- It is confusing as it implies these functions are called without PMU
although most of them are called only when a PMU is present.
- It makes semantics of functions fuzzy. For example, calling
kvm_pmu_disable_counter_mask() without PMU may result in no-op as
there are no enabled counters, but it's unclear what
kvm_pmu_get_counter_value() returns when there is no PMU.
- It allows callers without checking kvm_vcpu_has_pmu(vcpu), but it is
often wrong to call these functions without PMU.
- It is error-prone to duplicate kvm_vcpu_has_pmu(vcpu) checks into
multiple functions. Many functions are called for system registers,
and the system register infrastructure already employs less
error-prone, comprehensive checks.
Check kvm_vcpu_has_pmu(vcpu) in callers of these functions instead,
and remove the obsolete checks from pmu-emul.c. The only exceptions are
the functions that implement ioctls as they have definitive semantics
even when the PMU is not present.

PMOVS{SET,CLR}
Commit a45f41d754e0 ("KVM: arm64: Add {get,set}_user for
PM{C,I}NTEN{SET,CLR}, PMOVS{SET,CLR}") changed KVM_SET_ONE_REG to update
the mentioned registers in a way matching with the behavior of guest
register writes. This is a breaking change of a UAPI though the new
semantics looks cleaner and VMMs are not prepared for this.
Firecracker, QEMU, and crosvm perform migration by listing registers
with KVM_GET_REG_LIST, getting their values with KVM_GET_ONE_REG and
setting them with KVM_SET_ONE_REG. This algorithm assumes
KVM_SET_ONE_REG restores the values retrieved with KVM_GET_ONE_REG
without any alteration. However, bit operations added by the earlier
commit do not preserve the values retried with KVM_GET_ONE_REG and
potentially break migration.
Remove the bit operations that alter the values retrieved with
KVM_GET_ONE_REG.

The ASoC soc-utils driver does not require the creation of a platform
device. Originally, this approach was chosen for simplicity when the
driver was first implemented.
With the introduction of the lightweight faux device interface, we now
have a more appropriate alternative. Migrate the driver to utilize the
faux bus, given that the platform device it previously created was not
a real one anyway. This will simplify the code, reducing its footprint
while maintaining functionality.

These devices support polling for status updates and clearing peak

ECN bits in TOS are always cleared when sending in ACKs in TW. Clearing
them is problematic for TCP flows that used Accurate ECN because ECN bits
decide which service queue the packet is placed into (L4S vs Classic).
Effectively, TW ACKs are always downgraded from L4S to Classic queue
which might impact, e.g., delay the ACK will experience on the path
compared with the other packets of the flow.
Change the TW ACK sending code to differentiate:
- In tcp_v4_send_reset(), commit ba9e04a7ddf4f ("ip: fix tos reflection
in ack and reset packets") cleans ECN bits for TW reset and this is
not affected.
- In tcp_v4_timewait_ack(), ECN bits for all TW ACKs are cleaned. But now
only ECN bits of ACKs for oow data or paws_reject are cleaned, and ECN
bits of other ACKs will not be cleaned.
- In tcp_v4_reqsk_send_ack(), commit 66b13d99d96a1 ("ipv4: tcp: fix TOS
value in ACK messages sent from TIME_WAIT") did not clean ECN bits of
ACKs for oow data or paws_reject. But now the ECN bits rae cleaned for

There are important differences in how the CWR field behaves

Also, if CWR is there, set the Accurate ECN GSO flag to avoid

Handling the CWR flag differs between RFC 3168 ECN and AccECN.
With RFC 3168 ECN aware TSO (NETIF_F_TSO_ECN) CWR flag is cleared
starting from 2nd segment which is incompatible how AccECN handles
the CWR flag. Such super-segments are indicated by SKB_GSO_TCP_ECN.
With AccECN, CWR flag (or more accurately, the ACE field that also
includes ECE & AE flags) changes only when new packet(s) with CE
mark arrives so the flag should not be changed within a super-skb.
The new skb/feature flags are necessary to prevent such TSO engines
corrupting AccECN ACE counters by clearing the CWR flag (if the
CWR handling feature cannot be turned off).
If NIC is completely unaware of RFC3168 ECN (doesn't support
NETIF_F_TSO_ECN) or its TSO engine can be set to not touch CWR flag
despite supporting also NETIF_F_TSO_ECN, TSO could be safely used
with AccECN on such NIC. This should be evaluated per NIC basis
(not done in this patch series for any NICs).
For the cases, where TSO cannot keep its hands off the CWR flag,
a GSO fallback is provided by this patch.

Whenever timestamp advances, it declares progress which
can be used by the other parts of the stack to decide that
the ACK is the most recent one seen so far.
AccECN will use this flag when deciding whether to use the
ACK to update AccECN state or not.

- Move tcp_count_delivered() earlier and split tcp_count_delivered_ce()
out of it
- Move tcp_in_ack_event() later
- While at it, remove the inline from tcp_in_ack_event() and let
the compiler to decide
Accurate ECN's heuristics does not know if there is going
to be ACE field based CE counter increase or not until after
rtx queue has been processed. Only then the number of ACKed
bytes/pkts is available. As CE or not affects presence of
FLAG_ECE, that information for tcp_in_ack_event is not yet
available in the old location of the call to tcp_in_ack_event().

Objtool warnings can be indicative of crashes, broken live patching, or
even boot failures. Ignoring them is not recommended.
Add CONFIG_OBJTOOL_WERROR to upgrade objtool warnings to errors by
enabling the objtool --Werror option. Also set --backtrace to print the
branches leading up to the warning, which can help considerably when
debugging certain warnings.
To avoid breaking bots too badly for now, make it the default for real
world builds only (!COMPILE_TEST).
