DMA_ATTR_CC_SHARED describes an existing DMA mapping whose backing memory
is already shared, or decrypted, for confidential computing. It is a
mapping attribute: callers use it to request a shared DMA address encoding
for memory that has already been prepared for shared DMA.
Allocation paths need a related but different state. Once the DMA core
decides that an allocation must use shared backing pages, the lower-level
allocation helpers need to select shared pools, decrypt newly allocated
pages, derive the DMA address with the shared-memory translation and
restore encryption on free. That state is internal to the DMA-mapping
implementation and should not be passed by drivers to dma_alloc_attrs().

Introduce a new vCPU feature KVM_ARM_VCPU_PMU_V3_STRICT. When set, KVM
does not create a default PMU when initializing the vCPU, and userspace
must select one explicitly via KVM_ARM_VCPU_PMU_V3_SET_PMU before the
first KVM_RUN.
The flag forces the VMM to be aware of the PMU implementation of the
guest to be created, so that certain information about the PMU becomes
deterministic (if on a heterogeneous system) and becomes safe to be
exposed to the guest. It can be used as an umbrella flag to gate future
PMUv3 UAPI changes.
When no default PMU is created, kvm->arch.arm_pmu stays NULL until SET_PMU
runs, so kvm_arm_pmu_v3_init() now refuses to run if kvm->arch.arm_pmu
is NULL.

Add the missing power-domains property to associate DISPCC with RPMPD_CX.
This is to ensure the genpd performance state votes on the GDSC to get
propagated to the CX rail and to avoid the rail under-voltage conditions.
This change breaks ABI, as the power-domains property is marked as
required.

It's no longer used outside of mm/.
Since this means __alloc_pages_noprof() is no longer visible from gfp.h,
this also means moving the definition of alloc_pages_node_noprof into
the .c file.
Also remove references to this API from the documentation tree -
referring to the specific function name was already questionable but
now the function is not even public it definitely seems wrong.

The qcom,imem binding describes a single word in always-on SRAM shared
between the operating system (OS) and boot firmware. Before DDR is
initialized on the warm reset following a crash, firmware reads this
word to decide where to deliver the minidump, and the OS is expected to
select one of the destinations: either USB upload to a host PC or save
to on-device storage. If nothing is selected by the OS, USB is the
default.

Add a framework driver for Dreamchip RPPX1 ISP. The driver aims to
provide a framework for other V4L2 based drivers to drive the RPPX1
functionality. The reason for this split is that the RPPX1 IP itself do
not provide any DMA engines to drive data to/from the device, instead it
depends on other IP blocks to implement these features.
While the peripherals around the RPPX1 ISP used in different designs and
by different vendors are different the RPPX1 core itself is the same.
For this reason the framework solution to be able to split the Dreamchip
RPPX1 driver from vendors usage of it have been picked in hope to reduce
duplication of the common parts.
The design is to try and keep the surface of this framework as small as
possible. The intention of this change is to be able to fill all needs
of this.
* Two functions to create and destroy a RPPX1 instance, rppx1_create()
and rppx1_destory(). These are intended to be called in the users
probe and remove code paths.
* Two functions to start and stop the RPPX1 processing, rppx1_start()
and rppx1_stop(). These are intended to be called in the users
stream on and stream off code paths.
* One function to ask the RPPX1 to process parameters buffer prepared
by user space, rppx1_params(). The intention is to call this
function when the parameter buffer is queued to the V4L2 driver and
the result stored by the driver until the time it needs to be
written to the RPPX1. It's the users responsibility to write it
either using MMIO or other means.
* One function to fill in a statistic buffer based on the current
status of the RPPX1, rppx1_stats_fill_isr(). The intention is that
the user call's this in its interrupt handler when it knows the
RPPX1 is done processing a frame.
* One function to ack and retrieve the interrupts generated by the
RPPX1, rppx1_interrupt(). The intention is to call this function
when the users interrupt handler detects the RPPX1 have raised and
interrupt. There is no need for the user to understand, or act, on
the actual RPPX1 interrupt, but it can if it wants too.
The initial support in the framework is limited and do not implement any
ISP processing algorithms other then configuring the RPPX1 to process
any Bayer (8-, 10, or 12-bit) image and produce either a RGB or YUYV
output. It do however probe all function blocks of the RPPX1 and provide
an interface to interact with both parameter and statistic bufferers.
The user of the framework will not change as algorithms for the
different function blocks of the ISP are being added.

The Google Tensor G5 SoC (known as "laguna" and canonically written in
code as "lga") has a UART based on Designware IP. The UART appears to
work reasonably well, at least for serial console, with the existing
driver in Linux. Add a compatible for this UART based on the canonical
"lga" name for this SoC with a fallback to the existing
"snps,dw-apb-uart".

Older dtschema <2024.02 required custom select to avoid applying this
binding to anything having "syscon" compatible. That's not the case
anymore and this additional select has two headaches:
1. Duplicates all the compatibles listed in the schema.
2. Is error-prone, because it requires contributor to add the compatible
in two places, otherwise the schema will be silently ignored.
The select list already misses mentioning compatibles:
mediatek,mt8365-infracfg-nao and renesas,r9a08g046-lvds-cmn (with the
latter being reverted for different reasons).
This requires bumping minimum dtschema requirement to v2024.04, which
feels old enough to be a safe requirement.

"syscon" is a system controller with registers having their own
functions, thus not really a trivial MMIO simple bus. "simple-bus" on
the other hand is just a bus on which multiple devices sit and the
"simple" means no functions are allowed here.
Combination of both "syscon" and "simple-bus" is abuse of DT for easier
instantiating of Linux device drivers so add a schema to disallow that.
Unfortunately there are a few old cases of that patterns, so add
exceptions:
1. "cznic,turris1x-cpld" and "img,pistachio-cr-periph" are already used
in upstream DTS.
2. TI has several DTSI with a child of SCM device (e.g. "ti,am3-scm")
using "syscon" and "simple-bus" but without a dedicated compatible
documented anywhere. Add new compatibles for such cases.
Additionally, add comments around code enforcing two or three
compatibles: it is similar safeguard detecting incorrect bindings.

Large keepalive values can overflow the delayed-work delay on 32-bit
systems, causing the keepalive worker to be repeatedly scheduled.
A correct configuration should not require such large keepalive values,
and an upper limit of one day is already generous and unnecessary in
practice. Limit both the keepalive interval and timeout to 86400 seconds.
