There are 3 scenarios that leads to a locked region:
1. A region is created on a root decoder with Fixed Device Confiuration
attribute.
2. CXL_HDM_DECODER0_CTRL_LOCK.
Both 1 & 1 are well described in:
commit 2230c4bdc412 ("cxl: Add handling of locked CXL decoder")
3) Platform that has region creation with PRMT address translation always
locks the region, regardless of the FIXED attribute or decoder ctrl bit.
Region locked means region destroy operations are not permitted. CXL
region driver returns -EPERM for region destroy operations.
Although the locked status of the corresponding root decoder implies the
region is also locked, exposing the region lock status directly to
userspace improves usability for users who may not be aware of this
relationship.
[ dj: Amended commit log with additional locking scenarios. ]

Document USB2PHY reset controller bindings for RZ/G3E ("R9A09G047") SoC.
The RZ/G3E USB2PHY reset controller is functionally identical to the one
found on the RZ/V2H(P), so no driver changes are needed. The existing
"renesas,r9a09g057-usb2phy-reset" will be used as a fallback compatible
for this IP.

Add the '#mux-state-cells' property to support describing the USB VBUS_SEL
multiplexer as a mux-controller in the Renesas RZ/V2H(P) USB2PHY binding.
The mux-controller cannot be integrated into the parent USB2PHY node
because the VBUS source selector is part of a separate hardware block,
not the USB2PHY block itself.
This is required to properly configure USB PHY power selection on
RZ/V2H(P) and RZ/G3E SoCs.

Add bindings for the Awinic AW86938 haptic chip which can be found in

but have a register layout that's not 100% compatible.
Still, because chip model is fully detectable via ID register, these
chips can be documnented in the same file.

DRM Rust changes for v7.1-rc1
- DMA:
- Rework the DMA coherent API: introduce Coherent<T> as a generalized
container for arbitrary types, replacing the slice-only
CoherentAllocation<T>. Add CoherentBox for memory initialization
before exposing a buffer to hardware (converting to Coherent when
ready), and CoherentHandle for allocations without kernel mapping.
- Add Coherent::init() / init_with_attrs() for one-shot initialization
via pin-init, and from-slice constructors for both Coherent and
CoherentBox
- Add uaccess write_dma() for copying from DMA buffers to userspace
and BinaryWriter support for Coherent<T>
- DRM:
- Add GPU buddy allocator abstraction
- Add DRM shmem GEM helper abstraction
- Allow drm::Device to dispatch work and delayed work items to driver
private data
- Add impl_aref_for_gem_obj!() macro to reduce GEM refcount
boilerplate, and introduce DriverObject::Args for constructor
context
- Add dma_resv_lock helper and raw_dma_resv() accessor on GEM objects
- Clean up imports across the DRM module
- I/O:
- Merged via a signed tag from the driver-core tree: register!() macro
and I/O infrastructure improvements (IoCapable refactor, RelaxedMmio
wrapper, IoLoc trait, generic accessors, write_reg /
LocatedRegister)
- Nova (Core):
- Fix and harden the GSP command queue: correct write pointer
advancing, empty slot handling, and ring buffer indexing; add mutex
locking and make Cmdq a pinned type; distinguish wait vs no-wait
commands
- Add support for large RPCs via continuation records, splitting
oversized commands across multiple queue slots
- Simplify GSP sequencer and message handling code: remove unused
trait and Display impls, derive Debug and Zeroable where applicable,
warn on unconsumed message data
- Refactor Falcon firmware handling: create DMA objects lazily, add
PIO upload support, and use the Generic Bootloader to boot FWSEC on
Turing
- Convert all register definitions (PMC, PBUS, PFB, GC6, FUSE, PDISP,
Falcon) to the kernel register!() macro; add bounded_enum macro to
define enums usable as register fields
- Migrate all DMA usage to the new Coherent, CoherentBox, and
CoherentHandle APIs
- Harden firmware parsing with checked arithmetic throughout FWSEC,
Booter, RISC-V parsing paths
- Add debugfs support for reading GSP-RM log buffers; replace
module_pci_driver!() with explicit module init to support
module-level debugfs setup
- Fix auxiliary device registration for multi-GPU systems
- Various cleanups: import style, firmware parsing refactoring,
framebuffer size logging
- Rust:
- Add interop::list module providing a C linked list interface
- Extend num::Bounded with shift operations, into_bool(), and const
get() to support register bitfield manipulation
- Enable the generic_arg_infer Rust feature and add EMSGSIZE error
code
- Tyr:
- Adopt vertical import style per kernel Rust guidelines
- Clarify driver/device type names and use DRM device type alias
consistently across the driver
- Fix GPU model/version decoding in GpuInfo
- Workqueue:
- Add ARef<T> support for work and delayed work

The opid monitor validates that wakeup and need_resched events only
occur with interrupts and preemption disabled by following the
preemptirq tracepoints.
As reported in [1], those tracepoints might be inaccurate in some
situations (e.g. NMIs).
Since the monitor doesn't validate other ordering properties, remove the
dependency on preemptirq tracepoints and convert the monitor to a hybrid
automaton to validate the constraint during event handling.
This makes the monitor more robust by also removing the workaround for
interrupts missing the preemption tracepoints, which was working on
PREEMPT_RT only and allows the monitor to be built on kernels without
the preemptirqs tracepoints.

Introduce the new max_open_zones option to allow specifying a limit on
the maximum number of open zones of a zloop device. This change allows
creating a zloop device that can more closely mimick the characteristics
of a physical SMR drive.
When set to a non zero value, only up to max_open_zones zones can be in
the implicit open (BLK_ZONE_COND_IMP_OPEN) and explicit open
(BLK_ZONE_COND_EXP_OPEN) conditions at any time. The transition to the
implicit open condition of a zone on a write operation can result in an
implicit close of an already implicitly open zone. This is handled in
the function zloop_do_open_zone(). This function also handles
transitions to the explicit open condition. Implicit close transitions
are handled using an LRU ordered list of open zones which is managed
using the helper functions zloop_lru_rotate_open_zone() and

On PolarFire SoC there are more GPIO interrupts than there are interrupt
lines available on the PLIC, and a runtime configurable mux is used to
decide which interrupts are assigned direct connections to the PLIC &
which are relegated to sharing a line.

Add the devicetree binding for PCIe M.2 Mechanical Key E connector defined
in the PCI Express M.2 Specification, r4.0, sec 5.1.2. This connector
provides interfaces like PCIe or SDIO to attach the WiFi devices to the
host machine, USB or UART+PCM interfaces to attach the Bluetooth (BT)
devices. Spec also provides an optional interface to connect the UIM card,
but that is not covered in this binding.
The connector provides a primary power supply of 3.3v, along with an
optional 1.8v VIO supply for the Adapter I/O buffer circuitry operating at
1.8v sideband signaling.
The connector also supplies optional signals in the form of GPIOs for fine
grained power management.

Add I2C device IDs for Renesas RAA228942 and RAA228943.
At the Linux PMBus hwmon interface level currently supported by this

controllers, so devicetree will use fallback compatibles and no
dedicated OF match entries are needed.

Add support for the ITE IT8689E Super I/O chip. The IT8689E supports
newer autopwm, 12mV ADC, 16-bit fans, six fans, six PWM channels,
PWM frequency 2, six temperature inputs, AVCC3, temperature offset,
and fan on/off control.
Give it8689 its own GPIO configuration block in it87_find() rather
than sharing the it8620/it8628 block. The shared block reads
IT87_SIO_PINX2_REG and either marks IN3 as internal AVCC or skips
IN9. Because it8689 declares FEAT_AVCC3, IN9 is already marked as
always-internal before the GPIO block is reached; applying the PINX2
check would either create duplicate AVCC labels on IN3 and IN9 or
incorrectly skip IN9.
Also update Documentation/hwmon/it87.rst and drivers/hwmon/Kconfig to
document the newly supported chip.

The G and J coefficients provided by T-Head TH1520 manual (which calls
them A and C coefficients and calls H coefficient in the binding as B)
have 1/100 degree Celsius precision (the values are 42.74 and -0.16
respectively), however the binding currently only allows coefficients as
precise as 100 milli-Celsius (1/10 degree Celsius).
Change the multipleOf value of these two coefficients to 10 (in the unit
of milli-Celsius) to satisfy the need of TH1520.
