arm64: defconfig: Add IOSCHED_BFQ to the default configs
ARM64 systems are often memory constrained and more often than not
use slow single-channel storage such as flash memory or MMC/SD-cards.
For any interactive systems (such as mobile phones, tablets,
chromebooks...) the BFQ I/O scheduler will be desireable.
Make sure the BFQ I/O scheduler is available on these systems.
ARM (32), Loongarch, MIPS, m68k, UM and S390 has also enabled BFQ in
their defconfigs, cf commit

arm64: defconfig: Fix unintentional disablement of PCI on i.MX
A recent update to support PCI endpoint mode on i.MX platforms
unintentionally disabled PCI host support for i.MX in defconfig. The
existing PCI_IMX6 was made a hidden option, selected by new options
PCI_IMX6_HOST (for the existing support) and PCI_IMX6_EP (for the
endpoint mode), but there has been no corresponding update to defconfig
so the PCI_IMX6 ends up getting disabled. Switch defconfig to
PCI_IMX6_HOST to preserve the existing functionality.

Merge tag 'clk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux
Pull clk updates from Stephen Boyd:
"We have one small patch to the clk core this time around. It fixes a
corner case with the CLK_OPS_PARENT_ENABLE flag combined with
clk_core_is_enabled() where it hangs the system. We'll simply assume
the clk is disabled if the parent is disabled and the flag is set.
Trying to turn on the parent to check the enable state of the clk runs
into system hangs at boot. We let this bake in -next for a couple
weeks to make sure there aren't any more issues because the last
attempt to fix this ran into hangs and had to be reverted.
Note: There were some more patches to the core framework around
sync_state and disabling unused clks, but I asked for that to be
reverted from the qcom PR because it isn't ready and we're still
discussing the best solution on the list.
Outside of the core clk framework, we have the usual collection of clk
driver updates and support for new SoCs (which seems to never stop).
The dirstat is dominated by Qualcomm because they added support for
quite a few SoCs this time around and also migrated quite a few of
their drivers to clk_parent_data. The other big diff is in the
Mediatek clk drivers that saw a significant rework this cycle to
similarly modernize the code, and we'll see that work continue in the
next cycle as well. Nothing really jumps out as scary here, except
that the significant churn in parent data descriptions can have typos
that go unnoticed. More details below.
Core:
- Honor CLK_OPS_PARENT_ENABLE in clk_core_is_enabled()
New Drivers:
- Add a new clk-gpr-mux clock type and use it on i.MX6Q to add ENET
ref clocks
- Support for Mediatek MT7891 SoC clks
- Support for many Qualcomm clk controllers:
- QDU1000/QRU1000 global clock controller
- SA8775P global clock controller
- SM8550 TCSR and display clock controller
- SM6350 clock controller
- MSM8996 CBF and APCS clock controllers
Updates:
- Various cleanups and improvements to Mediatek clk drivers to reduce
code size and modernize the drivers
- Support for Versa 5P49V60 clks
- Disable R-Car H3 ES1.*, as it was only available to an internal
development group and needed a lot of quirks and workarounds
- Add PWM, Compare-Match Timer (TIM), USB, SDHI, and eMMC clocks and
resets on Renesas RZ/V2M
- Add display clocks on Renesas R-Car V4H
- Add Camera Receiving Unit (CRU) clocks and resets on Renesas RZ/G2L
- Free the imx_uart_clocks even if imx_register_uart_clocks returns
early
- Get the stdout clocks count from device tree on i.MX
- Drop the clock count argument from imx_register_uart_clocks()
- Keep the uart clocks on i.MX93 for when earlycon is used
- Fix SPDX comment in i.MX6SLL clocks bindings header
- Drop some unnecessary spaces from i.MX8ULP clocks bindings header
- Add imx_obtain_fixed_of_clock() for allowing to add a clock that is
not configured via devicetree
- Fix the ENET1 gate configuration for i.MX6UL according to the
reference manual
- Add ENET refclock mux support for i.MX6UL
- Add support for USB host/device configuration on Renesas RZ/N1
- Add PLL2 programming support, and CAN-FD clocks on Renesas R-Car
V4H
- Add D1 CAN bus gates and resets for Allwinner
- Mark D1 CPUX clock as critical on Allwinner
- Reuse D1 driver for Allwinner R528/T113
- Cleanup sunxi-ng Kconfig
- Fix sunxi-ng kernel-doc issues
- Model Allwinner H3/H5 DRAM clock as fixed clock
- Use .determine_rate() instead of .round_rate() for the dualdiv,
mpll, sclk-div and cpu-dyn-div amlogic clock drivers
- DDR clocks were marked as critical in the proper clock driver for
each AT91 SoC such that drivers/memory/atmel-sdramc.c to be deleted
in the next releases as it only does clock enablement
- Patch to avoid compiling dt-compat.o for all AT91 SoCs as only some
of them may use it
- Support synchronous power_off requests in the qcom GDSC driver for
proper GPU power collapse
- Drop test clocks from various Qualcomm clk drivers
- Update parent references to use clk_parent_data/clk_hw in various
Qualcomm clk drivers
- Fixes for the Qualcomm MSM8996 CPU clock controller
- Transition Qualcomm MSM8974 GCC off the externally defined
sleep_clk
- Add GDSCs in the global clock controller for Qualcomm QCS404
- The SDCC core clocks on Qualcomm SM6115 are moved to floor_ops
- Programming of clk_dis_wait for GPU CX GDSC on Qualcomm SC7180 and
SDM845 are moved to use the recently introduced properties in the
GDSC struct
- Qualcomm's RPMh clock driver gains SM8550 and SA8775P clocks, and
the IPA clock is added on a variety of platforms
- De-duplicate identical clks in Qualcomm SMD RPM clk driver
- Add a few missing clocks across msm8998, msm8992, msm8916, qcs404
to Qualcomm SDM RPM clk driver
- Various Qualcomm clk drivers use devm_pm_runtime_enable() to
simplify"

Merge tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm
Pull kvm updates from Paolo Bonzini:
"ARM:
- Provide a virtual cache topology to the guest to avoid
inconsistencies with migration on heterogenous systems. Non secure
software has no practical need to traverse the caches by set/way in
the first place
- Add support for taking stage-2 access faults in parallel. This was
an accidental omission in the original parallel faults
implementation, but should provide a marginal improvement to
machines w/o FEAT_HAFDBS (such as hardware from the fruit company)
- A preamble to adding support for nested virtualization to KVM,
including vEL2 register state, rudimentary nested exception
handling and masking unsupported features for nested guests
- Fixes to the PSCI relay that avoid an unexpected host SVE trap when
resuming a CPU when running pKVM
- VGIC maintenance interrupt support for the AIC
- Improvements to the arch timer emulation, primarily aimed at
reducing the trap overhead of running nested
- Add CONFIG_USERFAULTFD to the KVM selftests config fragment in the
interest of CI systems
- Avoid VM-wide stop-the-world operations when a vCPU accesses its
own redistributor
- Serialize when toggling CPACR_EL1.SMEN to avoid unexpected
exceptions in the host
- Aesthetic and comment/kerneldoc fixes
- Drop the vestiges of the old Columbia mailing list and add [Oliver]
as co-maintainer
RISC-V:
- Fix wrong usage of PGDIR_SIZE instead of PUD_SIZE
- Correctly place the guest in S-mode after redirecting a trap to the
guest
- Redirect illegal instruction traps to guest
- SBI PMU support for guest
s390:
- Sort out confusion between virtual and physical addresses, which
currently are the same on s390
- A new ioctl that performs cmpxchg on guest memory
- A few fixes
x86:
- Change tdp_mmu to a read-only parameter
- Separate TDP and shadow MMU page fault paths
- Enable Hyper-V invariant TSC control
- Fix a variety of APICv and AVIC bugs, some of them real-world, some
of them affecting architecurally legal but unlikely to happen in
practice
- Mark APIC timer as expired if its in one-shot mode and the count
underflows while the vCPU task was being migrated
- Advertise support for Intel's new fast REP string features
- Fix a double-shootdown issue in the emergency reboot code
- Ensure GIF=1 and disable SVM during an emergency reboot, i.e. give
SVM similar treatment to VMX
- Update Xen's TSC info CPUID sub-leaves as appropriate
- Add support for Hyper-V's extended hypercalls, where "support" at
this point is just forwarding the hypercalls to userspace
- Clean up the kvm->lock vs. kvm->srcu sequences when updating the
PMU and MSR filters
- One-off fixes and cleanups
- Fix and cleanup the range-based TLB flushing code, used when KVM is
running on Hyper-V
- Add support for filtering PMU events using a mask. If userspace
wants to restrict heavily what events the guest can use, it can now
do so without needing an absurd number of filter entries
- Clean up KVM's handling of "PMU MSRs to save", especially when vPMU
support is disabled
- Add PEBS support for Intel Sapphire Rapids
- Fix a mostly benign overflow bug in SEV's
send|receive_update_data()
- Move several SVM-specific flags into vcpu_svm
x86 Intel:
- Handle NMI VM-Exits before leaving the noinstr region
- A few trivial cleanups in the VM-Enter flows
- Stop enabling VMFUNC for L1 purely to document that KVM doesn't
support EPTP switching (or any other VM function) for L1
- Fix a crash when using eVMCS's enlighted MSR bitmaps
Generic:
- Clean up the hardware enable and initialization flow, which was
scattered around multiple arch-specific hooks. Instead, just let
the arch code call into generic code. Both x86 and ARM should
benefit from not having to fight common KVM code's notion of how to
do initialization
- Account allocations in generic kvm_arch_alloc_vm()
- Fix a memory leak if coalesced MMIO unregistration fails
selftests:
- On x86, cache the CPU vendor (AMD vs. Intel) and use the info to
emit the correct hypercall instruction instead of relying on KVM to
patch in VMMCALL
- Use TAP interface for kvm_binary_stats_test and tsc_msrs_test"

Merge tag 'driver-core-6.3-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core
Pull driver core updates from Greg KH:
"Here is the large set of driver core changes for 6.3-rc1.
There's a lot of changes this development cycle, most of the work
falls into two different categories:
- fw_devlink fixes and updates. This has gone through numerous review
cycles and lots of review and testing by lots of different devices.
Hopefully all should be good now, and Saravana will be keeping a
watch for any potential regression on odd embedded systems.
- driver core changes to work to make struct bus_type able to be
moved into read-only memory (i.e. const) The recent work with Rust
has pointed out a number of areas in the driver core where we are
passing around and working with structures that really do not have
to be dynamic at all, and they should be able to be read-only
making things safer overall. This is the contuation of that work
(started last release with kobject changes) in moving struct
bus_type to be constant. We didn't quite make it for this release,
but the remaining patches will be finished up for the release after
this one, but the groundwork has been laid for this effort.
Other than that we have in here:
- debugfs memory leak fixes in some subsystems
- error path cleanups and fixes for some never-able-to-be-hit
codepaths.
- cacheinfo rework and fixes
- Other tiny fixes, full details are in the shortlog
All of these have been in linux-next for a while with no reported
problems"

that there's a pending report that has a fix that is queued up - Linus ]

Merge tag 'efi-next-for-v6.3' of git://git.kernel.org/pub/scm/linux/kernel/git/efi/efi
Pull EFI updates from Ard Biesheuvel:
"A healthy mix of EFI contributions this time:
- Performance tweaks for efifb earlycon (Andy)
- Preparatory refactoring and cleanup work in the efivar layer, which
is needed to accommodate the Snapdragon arm64 laptops that expose
their EFI variable store via a TEE secure world API (Johan)
- Enhancements to the EFI memory map handling so that Xen dom0 can
safely access EFI configuration tables (Demi Marie)
- Wire up the newly introduced IBT/BTI flag in the EFI memory
attributes table, so that firmware that is generated with ENDBR/BTI
landing pads will be mapped with enforcement enabled
- Clean up how we check and print the EFI revision exposed by the
firmware
- Incorporate EFI memory attributes protocol definition and wire it
up in the EFI zboot code (Evgeniy)
This ensures that these images can execute under new and stricter
rules regarding the default memory permissions for EFI page
allocations (More work is in progress here)
- CPER header cleanup (Dan Williams)
- Use a raw spinlock to protect the EFI runtime services stack on
arm64 to ensure the correct semantics under -rt (Pierre)
- EFI framebuffer quirk for Lenovo Ideapad (Darrell)"

Merge tag 'net-next-6.3' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next
Pull networking updates from Jakub Kicinski:
"Core:
- Add dedicated kmem_cache for typical/small skb->head, avoid having
to access struct page at kfree time, and improve memory use.
- Introduce sysctl to set default RPS configuration for new netdevs.
- Define Netlink protocol specification format which can be used to
describe messages used by each family and auto-generate parsers.
Add tools for generating kernel data structures and uAPI headers.
- Expose all net/core sysctls inside netns.
- Remove 4s sleep in netpoll if carrier is instantly detected on
boot.
- Add configurable limit of MDB entries per port, and port-vlan.
- Continue populating drop reasons throughout the stack.
- Retire a handful of legacy Qdiscs and classifiers.
Protocols:
- Support IPv4 big TCP (TSO frames larger than 64kB).
- Add IP_LOCAL_PORT_RANGE socket option, to control local port range
on socket by socket basis.
- Track and report in procfs number of MPTCP sockets used.
- Support mixing IPv4 and IPv6 flows in the in-kernel MPTCP path
manager.
- IPv6: don't check net.ipv6.route.max_size and rely on garbage
collection to free memory (similarly to IPv4).
- Support Penultimate Segment Pop (PSP) flavor in SRv6 (RFC8986).
- ICMP: add per-rate limit counters.
- Add support for user scanning requests in ieee802154.
- Remove static WEP support.
- Support minimal Wi-Fi 7 Extremely High Throughput (EHT) rate
reporting.
- WiFi 7 EHT channel puncturing support (client & AP).
BPF:
- Add a rbtree data structure following the "next-gen data structure"
precedent set by recently added linked list, that is, by using
kfunc + kptr instead of adding a new BPF map type.
- Expose XDP hints via kfuncs with initial support for RX hash and
timestamp metadata.
- Add BPF_F_NO_TUNNEL_KEY extension to bpf_skb_set_tunnel_key to
better support decap on GRE tunnel devices not operating in collect
metadata.
- Improve x86 JIT's codegen for PROBE_MEM runtime error checks.
- Remove the need for trace_printk_lock for bpf_trace_printk and
bpf_trace_vprintk helpers.
- Extend libbpf's bpf_tracing.h support for tracing arguments of
kprobes/uprobes and syscall as a special case.
- Significantly reduce the search time for module symbols by
livepatch and BPF.
- Enable cpumasks to be used as kptrs, which is useful for tracing
programs tracking which tasks end up running on which CPUs in
different time intervals.
- Add support for BPF trampoline on s390x and riscv64.
- Add capability to export the XDP features supported by the NIC.
- Add __bpf_kfunc tag for marking kernel functions as kfuncs.
- Add cgroup.memory=nobpf kernel parameter option to disable BPF
memory accounting for container environments.
Netfilter:
- Remove the CLUSTERIP target. It has been marked as obsolete for
years, and we still have WARN splats wrt races of the out-of-band
/proc interface installed by this target.
- Add 'destroy' commands to nf_tables. They are identical to the
existing 'delete' commands, but do not return an error if the
referenced object (set, chain, rule...) did not exist.
Driver API:
- Improve cpumask_local_spread() locality to help NICs set the right
IRQ affinity on AMD platforms.
- Separate C22 and C45 MDIO bus transactions more clearly.
- Introduce new DCB table to control DSCP rewrite on egress.
- Support configuration of Physical Layer Collision Avoidance (PLCA)
Reconciliation Sublayer (RS) (802.3cg-2019). Modern version of
shared medium Ethernet.
- Support for MAC Merge layer (IEEE 802.3-2018 clause 99). Allowing
preemption of low priority frames by high priority frames.
- Add support for controlling MACSec offload using netlink SET.
- Rework devlink instance refcounts to allow registration and
de-registration under the instance lock. Split the code into
multiple files, drop some of the unnecessarily granular locks and
factor out common parts of netlink operation handling.
- Add TX frame aggregation parameters (for USB drivers).
- Add a new attr TCA_EXT_WARN_MSG to report TC (offload) warning
messages with notifications for debug.
- Allow offloading of UDP NEW connections via act_ct.
- Add support for per action HW stats in TC.
- Support hardware miss to TC action (continue processing in SW from
a specific point in the action chain).
- Warn if old Wireless Extension user space interface is used with
modern cfg80211/mac80211 drivers. Do not support Wireless
Extensions for Wi-Fi 7 devices at all. Everyone should switch to
using nl80211 interface instead.
- Improve the CAN bit timing configuration. Use extack to return
error messages directly to user space, update the SJW handling,
including the definition of a new default value that will benefit
CAN-FD controllers, by increasing their oscillator tolerance.

Merge tag 'soc-dt-6.3' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc
Pull SoC DT updates from Arnd Bergmann:
"About a quarter of the changes are for 32-bit arm, mostly filling in
device support for existing machines and adding minor cleanups, mostly
for Qualcomm and Samsung based machines.
Two new 32-bit SoCs are added, both are quad-core Cortex-A7 chips from
Rockchips that have been around for a while but were lacking kernel
support so far: RV1126 is a Vision SoC with an NPU and is used in the
Edgeble Neural Compute Module 2(Neu2) board, while RK3128 is design
for TV boxes and so far only comes with a dts for its refernece
design.
The other 32-bit boards that were added are two ASpeed AST2600 based
BMC boards, the Microchip sam9x60_curiosity development board (Armv5
based!), the Enclustra PE1 FPGA-SoM baseboard, and a few more boards
for i.MX53 and i.MX6ULL.
On the RISC-V side, there are fewer patches, but a total of ten new
single-board computers based on variations of the Allwinner D1/T113
chip, plus one more board based on Microchip Polarfire.
As usual, arm64 has by far the most changes here, with over 700
non-merge changesets, among them over 400 alone for Qualcomm. The
newly added SoCs this time are all recent high-end embedded SoCs for
various markets, each on comes with support for its reference board:
- Qualcomm SM8550 (Snapdragon 8 Gen 2) for mobile phones
- Qualcomm QDU1000/QRU1000 5G RAN platform
- Rockchips RK3588/RK3588s for tablets, chromebooks and SBCs
- TI J784S4 for industrial and automotive applications
In total, there are 46 new arm64 machines:
- Reference platforms for each of the five new SoCs
- Three Amlogic based development boards
- Six embedded machines based on NXP i.MX8MM and i.MX8MP
- The Mediatek mt7986a based Banana Pi R3 router
- Six tablets based on Qualcomm MSM8916 (Snapdragon 410), SM6115
(Snapdragon 662) and SM8250 (Snapdragon 865)
- Two LTE dongles, also based on MSM8916
- Seven mobile phones, based on Qualcomm MSM8953 (Snapdragon 610),
SDM450 and SDM632
- Three chromebooks based on Qualcomm SC7280 (Snapdragon 7c)
- Nine development boards based on Rockchips RK3588, RK3568, RK3566
and RK3328.
- Five development machines based on TI K3 (AM642/AM654/AM68/AM69)
The cleanup of dtc warnings continues across all platforms, adding to
the total number of changes"

arm64: fix .idmap.text assertion for large kernels
When building a kernel with many debug options enabled (which happens in test configurations use by myself and syzbot), the kernel can become large enough that portions of .text can be more than 128M away from .idmap.text (which is placed inside the .rodata section). Where idmap code branches into .text, the linker will place veneers in the .idmap.text section to make those branches possible. Unfortunately, as Ard reports, GNU LD has bseen observed to add 4K of padding when adding such veneers, e.g. | .idmap.text 0xffffffc01e48e5c0 0x32c arch/arm64/mm/proc.o | 0xffffffc01e48e5c0 idmap_cpu_replace_ttbr1 | 0xffffffc01e48e600 idmap_kpti_install_ng_mappings | 0xffffffc01e48e800 __cpu_setup | *fill* 0xffffffc01e48e8ec 0x4 | .idmap.text.stub | 0xffffffc01e48e8f0 0x18 linker stubs | 0xffffffc01e48f8f0 __idmap_text_end = . | 0xffffffc01e48f000 . = ALIGN (0x1000) | *fill* 0xffffffc01e48f8f0 0x710 | 0xffffffc01e490000 idmap_pg_dir = . This makes the __idmap_text_start .. __idmap_text_end region bigger than the 4K we require it to fit within, and triggers an assertion in arm64's vmlinux.lds.S, which breaks the build: | LD .tmp_vmlinux.kallsyms1 | aarch64-linux-gnu-ld: ID map text too big or misaligned | make[1]: *** [scripts/Makefile.vmlinux:35: vmlinux] Error 1 | make: *** [Makefile:1264: vmlinux] Error 2 Avoid this by using an `ADRP+ADD+BLR` sequence for branches out of .idmap.text, which avoids the need for veneers. These branches are only executed once per boot, and only when the MMU is on, so there should be no noticeable performance penalty in replacing `BL` with `ADRP+ADD+BLR`. At the same time, remove the "x" and "w" attributes when placing code in .idmap.text, as these are not necessary, and this will prevent the linker from assuming that it is safe to place PLTs into .idmap.text, causing it to warn if and when there are out-of-range branches within .idmap.text, e.g. | LD .tmp_vmlinux.kallsyms1 | arch/arm64/kernel/head.o: in function `primary_entry': | (.idmap.text+0x1c): relocation truncated to fit: R_AARCH64_CALL26 against symbol `dcache_clean_poc' defined in .text section in arch/arm64/mm/cache.o | arch/arm64/kernel/head.o: in function `init_el2': | (.idmap.text+0x88): relocation truncated to fit: R_AARCH64_CALL26 against symbol `dcache_clean_poc' defined in .text section in arch/arm64/mm/cache.o | make[1]: *** [scripts/Makefile.vmlinux:34: vmlinux] Error 1 | make: *** [Makefile:1252: vmlinux] Error 2 Thus, if future changes add out-of-range branches in .idmap.text, it should be easy enough to identify those from the resulting linker errors.

Merge tag 'kvmarm-6.3' of git://git.kernel.org/pub/scm/linux/kernel/git/kvmarm/kvmarm into HEAD
KVM/arm64 updates for 6.3 - Provide a virtual cache topology to the guest to avoid inconsistencies with migration on heterogenous systems. Non secure software has no practical need to traverse the caches by set/way in the first place. - Add support for taking stage-2 access faults in parallel. This was an accidental omission in the original parallel faults implementation, but should provide a marginal improvement to machines w/o FEAT_HAFDBS (such as hardware from the fruit company). - A preamble to adding support for nested virtualization to KVM, including vEL2 register state, rudimentary nested exception handling and masking unsupported features for nested guests. - Fixes to the PSCI relay that avoid an unexpected host SVE trap when resuming a CPU when running pKVM. - VGIC maintenance interrupt support for the AIC - Improvements to the arch timer emulation, primarily aimed at reducing the trap overhead of running nested. - Add CONFIG_USERFAULTFD to the KVM selftests config fragment in the interest of CI systems. - Avoid VM-wide stop-the-world operations when a vCPU accesses its own redistributor. - Serialize when toggling CPACR_EL1.SMEN to avoid unexpected exceptions in the host. - Aesthetic and comment/kerneldoc fixes - Drop the vestiges of the old Columbia mailing list and add [Oliver] as co-maintainer This also drags in arm64's 'for-next/sme2' branch, because both it and the PSCI relay changes touch the EL2 initialization code. |

as documented by the bindings.

arm64: dts: qcom: sc7280: Adjust zombie PWM frequency
Tune the PWM to solve screen flashing issue and high frequency noise. While at it, the comment for the PWM settings incorrectly said we were using a 5kHz duty cycle. It should have said "period", not "duty cycle". Correct this while updating the values.

arm64: dts: qcom: sc8280xp-pmics: Specify interrupt parent explicitly
Nodes like pwrkey, resin, iadc, adc-tm, temp-alarm which are the grand children of spmi_bus node represent the interrupt generating devices but don't have "interrupt-parent" property. As per the devicetree spec v0.3, section 2.4: "The physical wiring of an interrupt source to an interrupt controller is represented in the devicetree with the interrupt-parent property. Nodes that represent interrupt-generating devices contain an interrupt-parent property which has a phandle value that points to the device to which the device’s interrupts are routed, typically an interrupt controller. If an interrupt-generating device does not have an interrupt-parent property, its interrupt parent is assumed to be its devicetree parent." This clearly says that if the "interrupt-parent" property is absent, then the immediate devicetree parent will be assumed as the interrupt parent. But the immediate parents of these nodes are not interrupt controllers themselves. This may lead to failure while wiring the interrupt for these nodes by an operating system. But a few operating systems like Linux, workaround this issue by walking up the parent nodes until it finds the "interrupt-cells" property. Then the node that has the "interrupt-cells" property will be used as the interrupt parent. But this workaround is not as per the DT spec and is not being implemented by other operating systems such as OpenBSD. Hence, fix this issue by adding the "interrupts-extended" property that explicitly specifies the spmi_bus node as the interrupt parent. Note that the "interrupts-extended" property is chosen over "interrupt-parent" as it allows specifying both interrupt parent phandle and interrupt specifiers in a single property.

Currently the dts contains a mix of status-as-first-property (old qcom style) and status-as-last-property (new style). Move all status properties down to the bottom once and for all so that the style is consistent between different nodes.
