47a347bae9 soc: fsl: cpm1: tsa: Fix tsa_write8() 
The tsa_write8() parameter is an u32 value. This is not consistent with
the function itself. Indeed, tsa_write8() writes an 8bits value.

Be consistent and use an u8 parameter value.

The TRNSYNC feature is available (and enabled) only in transparent mode.

Since commit 7cc9bda9c1 ("soc: fsl: cpm1: qmc: Handle timeslot entries
at channel start() and stop()") TRNSYNC register is updated in
transparent and hdlc mode. In hdlc mode, the address of the TRNSYNC
register is used by the QMC for other internal purpose. Even if no weird
results were observed in hdlc mode, touching this register in this mode
is wrong.

Update TRNSYNC only in transparent mode.

c2a96b7f18 Driver core changes for 6.11-rc1 
Here is the big set of driver core changes for 6.11-rc1.
 
 Lots of stuff in here, with not a huge diffstat, but apis are evolving
 which required lots of files to be touched.  Highlights of the changes
 in here are:
   - platform remove callback api final fixups (Uwe took many releases to
     get here, finally!)
   - Rust bindings for basic firmware apis and initial driver-core
     interactions.  It's not all that useful for a "write a whole driver
     in rust" type of thing, but the firmware bindings do help out the
     phy rust drivers, and the driver core bindings give a solid base on
     which others can start their work.  There is still a long way to go
     here before we have a multitude of rust drivers being added, but
     it's a great first step.
   - driver core const api changes.  This reached across all bus types,
     and there are some fix-ups for some not-common bus types that
     linux-next and 0-day testing shook out.  This work is being done to
     help make the rust bindings more safe, as well as the C code, moving
     toward the end-goal of allowing us to put driver structures into
     read-only memory.  We aren't there yet, but are getting closer.
   - minor devres cleanups and fixes found by code inspection
   - arch_topology minor changes
   - other minor driver core cleanups
 
 All of these have been in linux-next for a very long time with no
 reported problems.

60c6119cad remoteproc updates for v6.11 
The maximum amount of DDR memory used by the Mediatek MT8188/MT8195 SCP
 is increased, to handle new use cases. Handling of optional L1TCM memory
 is made actually optional.
 An optimization is introduced to only clear the unused portion of IPI
 shared buffers, rather than the entire buffer before writing the
 message.
 
 Detection for IPC-only mode in the TI K3 DSP remoteproc driver is
 corrected. The loglevel of a debug print in the same is lowered from
 error.
 
 Support for attaching to an running remote processor is added to the
 Xilinx R5F.
 
 An in-kernel implementation of the Qualcomm "protected domain mapper"
 (aka service registry) service is introduced, to remove the dependency
 on a userspace implementation to detect when the battery monitor and USB
 Type-C port manager becomes available. This is then integrated with the
 Qualcomm remoteproc driver.
 
 The Qualcomm PAS remoteproc driver gains support for attempting to bust
 hwspinlocks held by the remote processor when it crashed/stopped.
 
 The TI OMAP remoteproc driver is transitioned to use devres helpers for
 various forms of allocations.
 
 Parsing of memory-regions in the i.MX remoteproc driver is improved to
 avoid a NULL pointer dereference if the phandle reference is empty.
 of_node reference counting is corrected in the same.

 - MIDI2 time-base extension in ALSA sequencer API
 
 ASoC:
 - Syncing of features between simple-audio-card and the two
   audio-graph cards
 - Support for specifying the order of operations for components
   within cards to allow quirking for unusual systems
 - Lots of DT schema conversions
 - Continued SOF/Intel updates for topology, SoundWire, IPC3/4
 - New support for Asahi Kasei AK4619, Cirrus Logic CS530x, Everest
   Semiconductors ES8311, NXP i.MX95 and LPC32xx, Qualcomm LPASS
   v2.5 and WCD937x, Realtek RT1318 and RT1320 and Texas

Linus Torvalds
51835949dd Networking changes for 6.11. Not much excitement - a handful of large 
patchsets (devmem among them) did not make it in time.
 
 Core & protocols
 ----------------
 
  - Use local_lock in addition to local_bh_disable() to protect per-CPU
    resources in networking, a step closer for local_bh_disable() not
    to act as a big lock on PREEMPT_RT.
 
  - Use flex array for netdevice priv area, ensure its cache alignment.
 
  - Add a sysctl knob to allow user to specify a default rto_min at socket
    init time. Bit of a big hammer but multiple companies were
    independently carrying such patch downstream so clearly it's useful.
 
  - Support scheduling transmission of packets based on CLOCK_TAI.
 
  - Un-pin TCP TIMEWAIT timer to avoid it firing on CPUs later cordoned off
    using cpusets.
 
  - Support multiple L2TPv3 UDP tunnels using the same 5-tuple address.
 
  - Allow configuration of multipath hash seed, to both allow synchronizing
    hashing of two routers, and preventing partial accidental sync.
 
  - Improve TCP compliance with RFC 9293 for simultaneous connect().
 
  - Support sending NAT keepalives in IPsec ESP in UDP states. Userspace
    IKE daemon had to do this before, but the kernel can better keep
    track of it.
 
  - Support sending supervision HSR frames with MAC addresses stored in
    ProxyNodeTable when RedBox (i.e. HSR-SAN) is enabled.
 
  - Introduce IPPROTO_SMC for selecting SMC when socket is created.
 
  - Allow UDP GSO transmit from devices with no checksum offload.
 
  - openvswitch: add packet sampling via psample, separating the sampled
    traffic from "upcall" packets sent to user space for forwarding.
 
  - nf_tables: shrink memory consumption for transaction objects.
 
 Things we sprinkled into general kernel code
 --------------------------------------------
 
  - Power Sequencing subsystem (used by Qualcomm Bluetooth driver
    for QCA6390).
 
  - Add IRQ information in sysfs for auxiliary bus.
 
  - Introduce guard definition for local_lock.
 
  - Add aligned flavor of __cacheline_group_{begin, end}() markings for
    grouping fields in structures.
 
 BPF
 ---
 
  - Notify user space (via epoll) when a struct_ops object is getting
    detached/unregistered.
 
  - Add new kfuncs for a generic, open-coded bits iterator.
 
  - Enable BPF programs to declare arrays of kptr, bpf_rb_root, and
    bpf_list_head.
 
  - Support resilient split BTF which cuts down on duplication and makes
    BTF as compact as possible WRT BTF from modules.
 
  - Add support for dumping kfunc prototypes from BTF which enables both
    detecting as well as dumping compilable prototypes for kfuncs.
 
  - riscv64 BPF JIT improvements in particular to add 12-argument support
    for BPF trampolines and to utilize bpf_prog_pack for the latter.
 
  - Add the capability to offload the netfilter flowtable in XDP layer
    through kfuncs.
 
 Driver API
 ----------
 
  - Allow users to configure IRQ tresholds between which automatic IRQ
    moderation can choose.
 
  - Expand Power Sourcing (PoE) status with power, class and failure
    reason. Support setting power limits.
 
  - Track additional RSS contexts in the core, make sure configuration
    changes don't break them.
 
  - Support IPsec crypto offload for IPv6 ESP and IPv4 UDP-encapsulated ESP
    data paths.
 
  - Support updating firmware on SFP modules.
 
 Tests and tooling
 -----------------
 
  - mptcp: use net/lib.sh to manage netns.
 
  - TCP-AO and TCP-MD5: replace debug prints used by tests with
    tracepoints.
 
  - openvswitch: make test self-contained (don't depend on OvS CLI tools).

Linus Torvalds
cc0f7c3f97 soc: driver updates for 6.11 
The updates to the mediatek, allwinner, ti, tegra, microchip, stm32,
 samsung, imx, zynq and amlogic platoforms are farily small maintenance
 changes, either addressing minor mistakes or enabling additional hardware.
 
 The qualcomm platform changes add a number of features and are larger
 than the other ones combined, introducing the use of linux/cleanup.h
 across several drivers, adding support for Snapdragon X1E and other
 SoCs in platform drivers, a new "protection domain mapper" driver, and a
 "shared memory bridge" driver.
 
 The cznic "turris omnia" router based on Marvell Armada gets a platform
 driver that talks to the board specific microcontroller.
 
 The reset and cache subsystems get a few minor updates to SoC specific
 drivers, while the ff-a, scmi and optee firmware drivers get some

Merge tag 'soc-drivers-6.11' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc

Pull SoC driver updates from Arnd Bergmann:
 "The updates to the mediatek, allwinner, ti, tegra, microchip, stm32,
  samsung, imx, zynq and amlogic platoforms are fairly small maintenance
  changes, either addressing minor mistakes or enabling additional
  hardware.

  The qualcomm platform changes add a number of features and are larger
  than the other ones combined, introducing the use of linux/cleanup.h
  across several drivers, adding support for Snapdragon X1E and other
  SoCs in platform drivers, a new "protection domain mapper" driver, and
  a "shared memory bridge" driver.

  The cznic "turris omnia" router based on Marvell Armada gets a
  platform driver that talks to the board specific microcontroller.

  The reset and cache subsystems get a few minor updates to SoC specific
  drivers, while the ff-a, scmi and optee firmware drivers get some code
  refactoring and new features"

soc: samsung: exynos-pmu: add support for PMU_ALIVE non atomic registers 
Not all registers in PMU_ALIVE block support atomic set/clear operations.
GS101_SYSIP_DAT0 and GS101_SYSTEM_CONFIGURATION registers are two regs
where attempting atomic access fails.

As documentation on exactly which registers support atomic operations is
not forthcoming. We default to atomic access, unless the register is
explicitly added to the tensor_is_atomic() function. Update the comment
to reflect this as well.

 The X1Elite platform is added to uefisecapp allow list, to instantiate
 the efivars implementation.
 
 A new in-kernel implementation of the pd-mapper (or servreg) service is
 introduced, to replace the userspace dependency for USB Type-C and
 battery management.

 and a refcount imbalance issue is corrected.
 
 The LLCC support for recent platforms is corrected, and SA8775P support
 is added.

d69d804845 driver core: have match() callback in struct bus_type take a const * 
In the match() callback, the struct device_driver * should not be
changed, so change the function callback to be a const *.  This is one
step of many towards making the driver core safe to have struct
device_driver in read-only memory.

Because the match() callback is in all busses, all busses are modified
to handle this properly.  This does entail switching some container_of()
calls to container_of_const() to properly handle the constant *.

For some busses, like PCI and USB and HV, the const * is cast away in
the match callback as those busses do want to modify those structures at
this point in time (they have a local lock in the driver structure.)
That will have to be changed in the future if they wish to have their
struct device * in read-only-memory.

e49380c155 soc: qcom: smp2p: Use devname for interrupt descriptions 
When using /proc/interrupts to collect statistics on smp2p interrupt
counts, it is hard to distinguish the different instances of smp2p from
each other. For example to debug a processor boot issue, the ready and
handover interrupts are checked for sanity to ensure the firmware
reached a specific initialization stage.

Remove "smp2p" string from the irq request so that the irq will default
to the device name. Add an .irq_print_chip() callback to print the irq
chip name as the device name. These two changes allow for a unique name
to be used in /proc/interrupts as shown below.

/ # cat /proc/interrupts | grep smp2p
 18:  ...      ipcc 196610 Edge      smp2p-adsp

drivers/soc/litex: drop obsolete dependency on COMPILE_TEST 
Since commit 0166dc11be ("of: make CONFIG_OF user selectable"), it
is possible to test-build any driver which depends on OF on any
architecture by explicitly selecting OF. Therefore depending on
COMPILE_TEST as an alternative is no longer needed.

It is actually better to always build such drivers with OF enabled,
so that the test builds are closer to how each driver will actually be
built on its intended target. Building them without OF may not test
much as the compiler will optimize out potentially large parts of the
code. In the worst case, this could even pop false positive warnings.
Dropping COMPILE_TEST here improves the quality of our testing and
avoids wasting time on non-existent issues.

As a minor optimization, this also lets us drop of_match_ptr() and
ifdef-guarding, as we now know what they will resolve to, we might as
well save cpp some work.

For SoCs like gs101 that need a special regmap, register this with
of_syscon_register_regmap api, so it can be returned by
syscon_regmap_lookup_by_phandle() and friends.

For SoCs that don't require a custom regmap, revert back to syscon
creating the mmio regmap rather than duplicating the logic here.

exynos_get_pmu_regmap_by_phandle() api is also updated to retrieve
the regmap via syscon. The exynos_get_pmu_regmap_by_phandle() api
is kept around until fw_devlink support for syscon property is added
for the pinctrl-samsung driver that also runs at postcore_initcall
level.

All other exynos client drivers can revert back to
syscon_regmap_lookup_by_phandle().

dc18836435 soc: qcom: icc-bwmon: Allow for interrupts to be shared across instances 
The multiple BWMONv4 instances available on the X1E80100 SoC use the
same interrupt number. Mark them are shared to allow for re-use across
instances.

Using IRQF_SHARED coupled with devm_request_threaded_irq implies that
the irq can still trigger during/after bwmon_remove due to other active
bwmon instances. Handle this race by relying on bwmon_disable to disable
the interrupt and coupled with explicit request/free irqs.

b65e697a7c dim: make DIMLIB dependent on NET 
DIMLIB's capabilities are supplied by the dim, net_dim, and
rdma_dim objects, and dim's interfaces solely act as a base for
net_dim and rdma_dim and are not explicitly used anywhere else.
rdma_dim is utilized by the infiniband driver, while net_dim
is for network devices, excluding the soc/fsl driver.

In this patch, net_dim relies on some NET's interfaces, thus
DIMLIB needs to explicitly depend on the NET Kconfig.

The soc/fsl driver uses the functions provided by net_dim, so
it also needs to depend on NET.
