Add compatible for ADC used in Mot board. Separate compatible is required
since ADC in the Mot board uses a unique set of configurations.

Add additional quotes from Linus while trimming the existing ones and
sorting them all into categories. That makes it easier for new
developers and maintainers to look up how Linus expects certain
situations wrt regressions to be handled. The earlier sections in the
document already explain this, but those parts are often questioned --
or not considered authoritative at all and plainly ignored. Having it
straight from the horse's mouth helps get everyone on the same page,
even if that makes the document quite a bit longer (the raw line count
of this section doubles, but the number of characters increases by
nearly 50%). In return, this covers a lot more aspects and, due to the
sub-headings, is easier to navigate.
In contrast to the more neutral description in the early sections of the
document, this also provides a better insight into how serious Linus is
about the "no regressions" rule and how he wants it to be interpreted in
practice; this makes it easier for new developers and maintainers to
understand things and prevent run-ins with higher-level maintainers.

Documenation/scheduler/sched-deadline.rst provides two examples for how
to setup cgroup and cpuset for deadline tasks: one for cgroup v1 and one
cgroup v2. The code block in the latter is not properly html rendered as
the :: marker is missing.
Add the :: marker before the code block for the cgroup v2 example to fix
html rendering.
Also make the example description more explicit for better clarity.

Over the time, most of the changes at kernel-doc are related
to maintaining a list of transforms to convert macros into pure
C code.
Place such transforms on a separate module, to cleanup the
parser module.
There is an advantage on that: QEMU also uses our own kernel-doc,
but the xforms list there is different. By placing it on a
separate module, we can minimize the differences and make it
easier to keep QEMU in sync with Kernel upstream.
No functional changes.

This binding documented clock-names, but never bothered to document what
the name should be, rendering the property useless to software. It's not
a required property, so it can just be removed without harming any
software that conjured up it's own name for the clock, as they could not
rely on it being there to begin with.

CoreSPI, CoreQSPI and the hardened versions of them on mpfs and
pic64gx have a reset pin. For the first two, usually this is wired to
a common fabric reset not managed by software and for the latter two
the platform firmware takes them out of reset on first-party boards
(or those using modified versions of the vendor firmware), but not all
boards may take this approach. Permit providing a reset in devicetree
for Linux, or other devicetree-consuming software, to use.

Describe 1..4 DSI lanes as supported. Internally, this bridge is
an ChipOne ICN6211 which loads its register configuration from a
dedicated storage and its I2C does not seem to be accessible. The
ICN6211 supports up to 4 DSI lanes, so this is a hard limit for
this bridge. The lane configuration is preconfigured in the bridge
for each of the WaveShare panels.

Merge series from Franz Schnyder <franz.schnyder@toradex.com>:
The IRQ_B pin is an open-drain output. The datasheet specifies, that the
IRQ_B pin is pulled low when any unmasked interrupt bit status
is changed, and it is released high once the application processor reads
the INT1 register. As it specifies a level-low behavior, it should not
force a falling-edge interrupt.
Remove the IRQF_TRIGGER_FALLING to not force the falling-edge interrupt
and instead rely on the flag from the device tree.
Set the IRQF_SHARED to be able to share the interrupt line with
other devices. If the interrupt has not been triggered by the PMIC,
return IRQ_NONE.

Explicitly document the ordering of vcpu->mutex being taken *outside* of
kvm->slots_lock. While somewhat unintuitive since vCPUs conceptually have
narrower scope than VMs, the scope of the owning object (vCPU versus VM)
doesn't automatically carry over to the lock. In this case, vcpu->mutex
has far broader scope than kvm->slots_lock. As Paolo put it, it's a
"don't worry about multiple ioctls at the same time" mutex that's intended
to be taken at the outer edges of KVM.
More importantly, arm64 and x86 have gained flows that take kvm->slots_lock
inside of vcpu->mutex. x86's kvm_inhibit_apic_access_page() is particularly
nasty, as slots_lock is taken quite deep within KVM_RUN, i.e. simply
swapping the ordering isn't an option.
Commit to the vcpu->mutex => kvm->slots_lock ordering, as vcpu->mutex
really is intended to be a "top-level" lock, whereas kvm->slots_lock is
"just" a helper lock.
Opportunistically document that vcpu->mutex is also taken outside of
slots_arch_lock, e.g. when allocating shadow roots on x86 (which is the
entire reason slots_arch_lock exists, as shadow roots must be allocated
while holding kvm->srcu)

-> kvm_mmu_reload()

-> kvm_mmu_load()

-> mmu_alloc_shadow_roots()

Even though the type of the 'groups' property of a pinmux node is
specified as string-array in pinmux-node.yaml, but trying to use
multiple strings causes dtbs_check warnings.
For example, checking the following dts ...
$ cat arch/arm64/boot/dts/marvell/armada-3720-test.dts
/dts-v1/;
#include "armada-372x.dtsi"
&pinctrl_nb {
pwm-gpio-pins {
groups = "pwm0", "pwm1", "pwm2", "pwm3";
function = "gpio";
};
};
... results in this warning:
arch/arm64/boot/dts/marvell/armada-3720-test.dtb: pinctrl@13800 (marvell,armada3710-nb-pinctrl): pwm-gpio-pins:groups: ['pwm0', 'pwm1', 'pwm2', 'pwm3'] is too long
from schema $id: http://devicetree.org/schemas/pinctrl/marvell,armada3710-xb-pinctrl.yaml
Add the missing 'items' keyword to the schema to allow using multiple
strings without such warnings. Also adjust the indentation of the next
statements accordingly.

Pull kvm fixes from Paolo Bonzini:
"Arm:
- Make sure we don't leak any S1POE state from guest to guest when
the feature is supported on the HW, but not enabled on the host
- Propagate the ID registers from the host into non-protected VMs
managed by pKVM, ensuring that the guest sees the intended feature
set
- Drop double kern_hyp_va() from unpin_host_sve_state(), which could
bite us if we were to change kern_hyp_va() to not being idempotent
- Don't leak stage-2 mappings in protected mode
- Correctly align the faulting address when dealing with single page
stage-2 mappings for PAGE_SIZE > 4kB
- Fix detection of virtualisation-capable GICv5 IRS, due to the
maintainer being obviously fat fingered... [his words, not mine]
- Remove duplication of code retrieving the ASID for the purpose of
S1 PT handling
- Fix slightly abusive const-ification in vgic_set_kvm_info()
Generic:
- Remove internal Kconfigs that are now set on all architectures
- Remove per-architecture code to enable KVM_CAP_SYNC_MMU, all
architectures finally enable it in Linux 7.0"
* tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm:
KVM: always define KVM_CAP_SYNC_MMU
KVM: remove CONFIG_KVM_GENERIC_MMU_NOTIFIER
KVM: arm64: Deduplicate ASID retrieval code
irqchip/gic-v5: Fix inversion of IRS_IDR0.virt flag
KVM: arm64: Revert accidental drop of kvm_uninit_stage2_mmu() for non-NV VMs
KVM: arm64: Fix protected mode handling of pages larger than 4kB
KVM: arm64: vgic: Handle const qualifier from gic_kvm_info allocation type
KVM: arm64: Remove redundant kern_hyp_va() in unpin_host_sve_state()
KVM: arm64: Fix ID register initialization for non-protected pKVM guests
KVM: arm64: Optimise away S1POE handling when not supported by host
KVM: arm64: Hide S1POE from guests when not supported by the host

ADAQ4216 and ADAQ4224 are similar to AD4030 except that ADAQ devices have a
PGA (programmable gain amplifier) that scales the input signal prior to it
reaching the ADC inputs. The PGA is controlled through a couple of pins (A0
and A1) that set one of four possible signal gain configurations.
