The Turing RK1 contains 3 different USBs:
- USB0: USB 2.0, OTG
- USB1: USB 3.0, host
- USB2: USB 2.0, host
This patch activates the necessary DT nodes to enable all 3 buses.
Future work will be needed on USB0: it is not USB3-capable, so the USB0
controller needs to be told that there is no USB3 port. Per Jonas's
suggestion, the USBDP0 node is given a `rockchip,dp-lane-mux` property
that tells the USBDP driver that USBDP0 is not involved in USB so that
it can make the necessary configuration changes in hardware.
Technically, this is USB *controller* configuration, not *PHY*
configuration, so the underlying code may be moved in the future to the
USB controller driver instead, freeing up the (software) dependency on
USBDP0. A TODO comment is added to explain this.

The Powkiddy RGB20SX is a portable game console extremely similar to
the existing RGB30 console. The key differences from the RGB30 are
as follows:
- Realtek RTW8723DS WiFi and Bluetooth.
- UART pads for debug console (UART2).
- A function button (ADC channel 0).
- A much larger battery (5000 mAh).
Otherwise, the device is identical to the RGB30, including the
hard-coded value on ADC channel 1 used to identify the device at
runtime.

There is a PWRBTN# input pin exposed on a Q7 connector. The pin
is routed to a GPIO0_A1 through a diode. Q7 specification describes
the PWRBTN# pin as a Power Button signal.
Configure the pin as KEY_POWER, so it can function as power button and
trigger device shutdown.

Enable the Mali GPU in the Turing RK1.
This patch also sets the external GPU voltage regulator in the RK806-1
to "always-on" because it is necessary for this regulator to be active
when enabling the GPU power domain or the kernel will fail with:
rockchip-pm-domain fd8d8000.power-management:power-controller: \
failed to set domain 'gpu', val=0
rockchip-pm-domain fd8d8000.power-management:power-controller: \
failed to get ack on domain 'gpu', val=0x1bffff
...followed by a panic when it attempts to access unavailable QoS
registers.
Since there is currently no `domain-supply` or similar to express this
dependency, the only way to ensure that the regulator is never off when
the GPU power domain is brought up is to ensure that the regulator is
never off.

This patch adds thermal trip points and cooling maps to the Turing RK1
in order to enable automatic control of the external PWM fan. The fan is
not active below 45C, as the heatsink alone can generally keep the chip
in this temperature region at idle load. This cooling profile errs on
the side of quietness, since the RK1 is commonly deployed in a Turing
Pi 2 clusterboard alongside three others, with additional cooling
provided at the chassis level.

The PCIe 3 PHY in the RK3588 requires a running external reference clock
for both external bus transfers and some internal PIPE operations.
Without this clock, the PCIe3 controller fails to initialize and ignores
DBI transactions indefinitely, which stalls the Linux boot process.
On most RK3588 boards, this is evidently not an issue. But on some "SoM"
designs (Turing RK1, Mixtile Core 3588E, ArmSoM AIM7, to name a few),
this clock is only provided when the CLKREQ# signal is asserted.
The PCIe 3 PHY generates the CLKREQ# signal when it knows it needs the
reference clock for proper operation. Unfortunately, the current DT for
Turing RK1 does not mux out these low-speed signals, resulting in broken
boots and potentially other issues.
This patch, following the previous one that split up the PCIe pinctrls,
resolves this problem for Turing RK1 by explicitly muxing all of the
signals needed for PCIe 2 and 3 support.

These pinctrls manage the low-speed PCIe signals:
- CLKREQ#: An output on the RK3588 (both RC or EP modes), used to
request that external clock-generation circuitry provide a clock.
- PERST#: An input on the RK3588 in EP mode, used to detect a reset
signal from the RC. In RC mode, the hardware does not use this signal:
Linux itself generates it by putting the pin in GPIO mode.
- WAKE#: In EP mode, this is an output; in RC mode, this is an input.
Each of these signals serves a distinct purpose, and more importantly,
PERST# should not be muxed when the RK3588 is in the RC role. Bundling
them together in pinctrl groups prevents proper use: indeed, almost none
of the current board-specific .dts files make any use of them.
(Exception: Rock 5A recently had a patch land that misuses _pins; this
patch corrects that.)
However, on some RK3588 boards, the PCIe 3 controller will indefinitely
stall the boot if CLKREQ# is not muxed (details in the next patch).
This patch unbundles the signals to allow them to be used.

Ringneck v1.4 can contain (placement option) an on-board ATtiny
microcontroller instead of an STM32. In normal operation, this
is transparent to the software, as both microcontrollers emulate
the same ICs (amc6821 and isl1208).
For flashing the ATtiny, the SWITCH_REG1 regulator of the board's PMIC is
used to enable the ATtiny UPDI debug interface. If the STM32 is placed, or if
we are running on an older Ringneck revision, SWITCH_REG1 is not connected
and has no effect.
Add attiny-updi-gate-regulator so userspace can control it via sysfs

The cpu_emergency_register_virt_callback() function is used

conditionally:
#if IS_ENABLED(CONFIG_KVM_INTEL) || IS_ENABLED(CONFIG_KVM_AMD)
void cpu_emergency_register_virt_callback(cpu_emergency_virt_cb *callback);
...
leading to a build error when neither KVM_INTEL nor KVM_AMD support is
enabled:
arch/x86/kvm/x86.c: In function ‘kvm_arch_enable_virtualization’:
arch/x86/kvm/x86.c:12517:9: error: implicit declaration of function ‘cpu_emergency_register_virt_callback’ [-Wimplicit-function-declaration]

Fix the build by defining empty helper functions the same way the old
cpu_emergency_disable_virtualization() function was dealt with for the
same situation.
Maybe we could instead have made the call sites conditional, since the
callers (kvm_arch_{en,dis}able_virtualization()) have an empty weak
fallback. I'll leave that to the kvm people to argue about, this at
least gets the build going for that particular config.

Pull more bcachefs updates from Kent Overstreet:
"Assorted minor syzbot fixes, and for bigger stuff:
Fix two disk accounting rewrite bugs:
- Disk accounting keys use the version field of bkey so that journal
replay can tell which updates have been applied to the btree.
This is set in the transaction commit path, after we've gotten our
journal reservation (and our time ordering), but the
BCH_TRANS_COMMIT_skip_accounting_apply flag that journal replay
uses was incorrectly skipping this for new updates generated prior
to journal replay.
This fixes the underlying cause of an assertion pop in
disk_accounting_read.
- A couple of fixes for disk accounting + device removal.
Checking if acocunting replicas entries were marked in the
superblock was being done at the wrong point, when deltas in the
journal could still zero them out, and then additionally we'd try
to add a missing replicas entry to the superblock without checking
if it referred to an invalid (removed) device.
A whole slew of repair fixes:
- fix infinite loop in propagate_key_to_snapshot_leaves(), this fixes
an infinite loop when repairing a filesystem with many snapshots
- fix incorrect transaction restart handling leading to occasional
"fsck counted ..." warnings
- fix warning in __bch2_fsck_err() for bkey fsck errors
- check_inode() in fsck now correctly checks if the filesystem was

The isomorphism neg_if_exp negates the test of a ?: conditional,
making it unnecessary to have an explicit case for a negated test
with the branches inverted.
At the same time, we can disable neg_if_exp in cases where a
different API function may be more suitable for a negated test.
Finally, in the non-patch cases, E matches an expression with
parentheses around it, so there is no need to mention ()
explicitly in the pattern. The () are still needed in the patch
cases, because we want to drop them, if they are present.

The parentheses are only needed if there is a disjunction, ie a
set of possible changes. If there is only one pattern, we can
remove these parentheses. Just like the format:
- x
+ y
not:
(
- x
+ y
)

Pull x86 kvm updates from Paolo Bonzini:
"x86:
- KVM currently invalidates the entirety of the page tables, not just
those for the memslot being touched, when a memslot is moved or
deleted.
This does not traditionally have particularly noticeable overhead,
but Intel's TDX will require the guest to re-accept private pages
if they are dropped from the secure EPT, which is a non starter.
Actually, the only reason why this is not already being done is a
bug which was never fully investigated and caused VM instability
with assigned GeForce GPUs, so allow userspace to opt into the new
behavior.
- Advertise AVX10.1 to userspace (effectively prep work for the
"real" AVX10 functionality that is on the horizon)
- Rework common MSR handling code to suppress errors on userspace
accesses to unsupported-but-advertised MSRs
This will allow removing (almost?) all of KVM's exemptions for
userspace access to MSRs that shouldn't exist based on the vCPU
model (the actual cleanup is non-trivial future work)
- Rework KVM's handling of x2APIC ICR, again, because AMD (x2AVIC)
splits the 64-bit value into the legacy ICR and ICR2 storage,
whereas Intel (APICv) stores the entire 64-bit value at the ICR
offset
- Fix a bug where KVM would fail to exit to userspace if one was
triggered by a fastpath exit handler
- Add fastpath handling of HLT VM-Exit to expedite re-entering the
guest when there's already a pending wake event at the time of the
exit
- Fix a WARN caused by RSM entering a nested guest from SMM with
invalid guest state, by forcing the vCPU out of guest mode prior to
signalling SHUTDOWN (the SHUTDOWN hits the VM altogether, not the
nested guest)
- Overhaul the "unprotect and retry" logic to more precisely identify
cases where retrying is actually helpful, and to harden all retry
paths against putting the guest into an infinite retry loop
- Add support for yielding, e.g. to honor NEED_RESCHED, when zapping
rmaps in the shadow MMU
- Refactor pieces of the shadow MMU related to aging SPTEs in
prepartion for adding multi generation LRU support in KVM
- Don't stuff the RSB after VM-Exit when RETPOLINE=y and AutoIBRS is
enabled, i.e. when the CPU has already flushed the RSB
- Trace the per-CPU host save area as a VMCB pointer to improve
readability and cleanup the retrieval of the SEV-ES host save area
- Remove unnecessary accounting of temporary nested VMCB related
allocations
- Set FINAL/PAGE in the page fault error code for EPT violations if
and only if the GVA is valid. If the GVA is NOT valid, there is no
guest-side page table walk and so stuffing paging related metadata
is nonsensical
- Fix a bug where KVM would incorrectly synthesize a nested VM-Exit
instead of emulating posted interrupt delivery to L2
- Add a lockdep assertion to detect unsafe accesses of vmcs12
structures
- Harden eVMCS loading against an impossible NULL pointer deref
(really truly should be impossible)
- Minor SGX fix and a cleanup
- Misc cleanups
Generic:
- Register KVM's cpuhp and syscore callbacks when enabling
virtualization in hardware, as the sole purpose of said callbacks
is to disable and re-enable virtualization as needed
- Enable virtualization when KVM is loaded, not right before the
first VM is created
Together with the previous change, this simplifies a lot the logic
of the callbacks, because their very existence implies
virtualization is enabled
- Fix a bug that results in KVM prematurely exiting to userspace for
coalesced MMIO/PIO in many cases, clean up the related code, and
add a testcase
- Fix a bug in kvm_clear_guest() where it would trigger a buffer
overflow _if_ the gpa+len crosses a page boundary, which thankfully
is guaranteed to not happen in the current code base. Add WARNs in
more helpers that read/write guest memory to detect similar bugs
Selftests:
- Fix a goof that caused some Hyper-V tests to be skipped when run on
bare metal, i.e. NOT in a VM
- Add a regression test for KVM's handling of SHUTDOWN for an SEV-ES
guest
- Explicitly include one-off assets in .gitignore. Past Sean was
completely wrong about not being able to detect missing .gitignore
entries
- Verify userspace single-stepping works when KVM happens to handle a
VM-Exit in its fastpath
- Misc cleanups"
