Document the Synaptics TDDI (Touch/Display Integration) panel hardware.
Along with the MIPI-DSI panel, these devices also have an in-built LED
backlight device and a touchscreen, all packed together in a single chip.
Also, add compatibles for supported panels - TD4101 and TD4300. Both
have the '-panel' suffix so as to remove any ambiguity between the panel
and touchscreen chips.

Rework the current allOf: section such that all handling of
clocks/clock-names properties happens first, and all handling
of power-domains/power-domain-names happens second.
This allows the allOf section to limit various GPU models to
matching clocks count in the first half, and apply the same
for power-domains count in the second half, without conflating
the two limits together.
This makes addition of GPU models with different clocks and
power-domains count easier. No functional change intended.

"ARM:
- Fix the handling of ZCR_EL2 in NV VMs
- Pick the correct translation regime when doing a PTW on the back of
a SEA
- Prevent userspace from injecting an event into a vcpu that isn't
initialised yet
- Move timer save/restore to the sysreg handling code, fixing EL2
timer access in the process
- Add FGT-based trapping of MDSCR_EL1 to reduce the overhead of debug
- Fix trapping configuration when the host isn't GICv3
- Improve the detection of HCR_EL2.E2H being RES1
- Drop a spurious 'break' statement in the S1 PTW
- Don't try to access SPE when owned by EL3
Documentation updates:
- Document the failure modes of event injection
- Document that a GICv3 guest can be created on a GICv5 host with
FEAT_GCIE_LEGACY
Selftest improvements:
- Add a selftest for the effective value of HCR_EL2.AMO
- Address build warning in the timer selftest when building with
clang
- Teach irqfd selftests about non-x86 architectures
- Add missing sysregs to the set_id_regs selftest
- Fix vcpu allocation in the vgic_lpi_stress selftest
- Correctly enable interrupts in the vgic_lpi_stress selftest
x86:
- Expand the KVM_PRE_FAULT_MEMORY selftest to add a regression test
for the bug fixed by commit 3ccbf6f470 ("KVM: x86/mmu: Return
-EAGAIN if userspace deletes/moves memslot during prefault")
- Don't try to get PMU capabilities from perf when running a CPU with
hybrid CPUs/PMUs, as perf will rightly WARN.
guest_memfd:
- Rework KVM_CAP_GUEST_MEMFD_MMAP (newly introduced in 6.18) into a
more generic KVM_CAP_GUEST_MEMFD_FLAGS
- Add a guest_memfd INIT_SHARED flag and require userspace to
explicitly set said flag to initialize memory as SHARED,
irrespective of MMAP.
The behavior merged in 6.18 is that enabling mmap() implicitly
initializes memory as SHARED, which would result in an ABI
collision for x86 CoCo VMs as their memory is currently always
initialized PRIVATE.
- Allow mmap() on guest_memfd for x86 CoCo VMs, i.e. on VMs with
private memory, to enable testing such setups, i.e. to hopefully
flush out any other lurking ABI issues before 6.18 is officially
released.
- Add testcases to the guest_memfd selftest to cover guest_memfd
without MMAP, and host userspace accesses to mmap()'d private

Aside from the main CMA region, it can be useful to allow userspace to
allocate from the other CMA reserved regions.
Indeed, those regions can have specific properties that can be useful to
a specific us-case.
For example, one of them platform I've been with has ECC enabled on the
entire memory but for a specific region. Using that region to allocate
framebuffers can be particular beneficial because enabling the ECC has a
performance and memory footprint cost.
Thus, exposing these regions as heaps user-space can allocate from and
import wherever needed allows to cover that use-case.
For now, only shared-dma-pools regions with the reusable property (ie,
backed by CMA) are supported, but eventually we'll want to support other
DMA pools types.
Since we collected all the CMA regions created during boot, we can
simply iterate over all of them to create the heaps.
This has a weird interaction with the recent work on the CMA name, in
particular the backward compatibility code created by commit
854acbe75f ("dma-buf: heaps: Give default CMA heap a fixed name").
Indeed, the old name was either 'reserved', or the name of the
reserved-memory region device tree node if the linux,cma-default
property was set.
In both these cases, we have now collected this region during boot, and
we're using the same name. So we're now largely redundant with the
code to handle backward compatibility code, and we can thus remove it
and the associated Kconfig option.

Since we're going to introduce multiple instances of the CMA heap
driver, there's no single CMA heap anymore.
Let's use the heap name instead to differentiate between all the heaps
available in the system.
While we're at it, let's also rework the backward compatibility part to
make it easier to amend later on.
