The Linux Automation LXA TAC generation 3 is built around an
OSD32MP153x SiP with CPU, RAM, PMIC, Oscillator and EEPROM.
LXA TACs are a development tool for embedded devices with a focus on
embedded Linux devices.
Add compatible for the generation 3 based on the STM32MP153c.

Pull scheduler fixes from Borislav Petkov:
- Remove wrong enqueueing of a task for a later wakeup when a task
blocks on a RT mutex
- Do not setup a new deadline entity on a boosted task as that has
happened already
- Update preempt= kernel command line param
- Prevent needless softirqd wakeups in the idle task's context
- Detect the case where the idle load balancer CPU becomes busy and
avoid unnecessary load balancing invocation
- Remove an unnecessary load balancing need_resched() call in
nohz_csd_func()
- Allow for raising of SCHED_SOFTIRQ softirq type on RT but retain the
warning to catch any other cases
- Remove a wrong warning when a cpuset update makes the task affinity
no longer a subset of the cpuset

Each TAD provides eight 64-bit counters for monitoring
cache behavior.The driver always configures the same counter for
all the TADs. The user would end up effectively reserving one of
eight counters in every TAD to look across all TADs.
The occurrences of events are aggregated and presented to the user
at the end of running the workload. The driver does not provide a
way for the user to partition TADs so that different TADs are used for
different applications.
The performance events reflect various internal or interface activities.
By combining the values from multiple performance counters, cache
performance can be measured in terms such as: cache miss rate, cache
allocations, interface retry rate, internal resource occupancy, etc.
Each supported counter's event and formatting information is exposed
to sysfs at /sys/devices/tad/. Use perf tool stat command to measure
the pmu events. For instance:
perf stat -e tad_hit_ltg,tad_hit_dtg <workload>

Odyssey DRAM Subsystem supports eight counters for monitoring performance
and software can program those counters to monitor any of the defined
performance events. Supported performance events include those counted
at the interface between the DDR controller and the PHY, interface between
the DDR Controller and the CHI interconnect, or within the DDR Controller.
Additionally DSS also supports two fixed performance event counters, one
for ddr reads and the other for ddr writes.

Some NVIDIA PMUs like the NVLINK-C2C, CNVLINK, and PCIE PMU provide
port filtering. If the port filter is set to zero, the counter of
these PMUs will not capture any event. To avoid meaningless
experiment, the driver sets the port filter value to a default
non-zero value.

Add "stack_order" sysfs attribute which holds the order in which a live
patch module was loaded into the system. A user can then determine an
active live patched version of a function.
cat /sys/kernel/livepatch/livepatch_1/stack_order -> 1
means that livepatch_1 is the first live patch applied
cat /sys/kernel/livepatch/livepatch_module/stack_order -> N
means that livepatch_module is the Nth live patch applied

The Extcon (External Connector) subsystem driver lacked proper
documentation. This commit adds comprehensive documentation
explaining the purpose, key components, and usage of the Extcon
framework.
The new documentation includes:
- An overview of the Extcon subsystem
- Descriptions of key structures
- Explanations of core functions
- Information on the sysfs interface
- A usage example for driver developers

Add the adis16486, adis16487 and adis16489 Six Degrees
of Freedom Inertial Sensors to the list of compatible devices
of the adis16480 iio subsystem driver.
adis16486 is similar to adis16485, has the exact same channels
but acceleration and delta velocity scales are different.
adis16487 is fallback compatible with adis16485 and as a
consequence, dt-bindings list was updated to use oneOf.
adis16489 is similar to adis16488 but lacks the magnetometer
and has a different accelerometer scale.

Pull arm64 fixes from Catalin Marinas:
"Nothing major, some left-overs from the recent merging window (MTE,
coco) and some newly found issues like the ptrace() ones.
- MTE/hugetlbfs:
- Set VM_MTE_ALLOWED in the arch code and remove it from the core
code for hugetlbfs mappings
- Fix copy_highpage() warning when the source is a huge page but
not MTE tagged, taking the wrong small page path
- drivers/virt/coco:
- Add the pKVM and Arm CCA drivers under the arm64 maintainership
- Fix the pkvm driver to fall back to ioremap() (and warn) if the
MMIO_GUARD hypercall fails
- Keep the Arm CCA driver default 'n' rather than 'm'
- A series of fixes for the arm64 ptrace() implementation,
potentially leading to the kernel consuming uninitialised stack
variables when PTRACE_SETREGSET is invoked with a length of 0
- Fix zone_dma_limit calculation when RAM starts below 4GB and
ZONE_DMA is capped to this limit
- Fix early boot warning with CONFIG_DEBUG_VIRTUAL=y triggered by a
call to page_to_phys() (from patch_map()) which checks pfn_valid()
before vmemmap has been set up
- Do not clobber bits 15:8 of the ASID used for TTBR1_EL1 and TLBI
ops when the kernel assumes 8-bit ASIDs but running under a
hypervisor on a system that implements 16-bit ASIDs (found running
Linux under Parallels on Apple M4)
- ACPI/IORT: Add PMCG platform information for HiSilicon HIP09A as it
is using the same SMMU PMCG as HIP09 and suffers from the same
errata
- Add GCS to cpucap_is_possible(), missed in the recent merge"
