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.

9722c3b66e of: remove internal arguments from of_property_for_each_u32() 
The of_property_for_each_u32() macro needs five parameters, two of which
are primarily meant as internal variables for the macro itself (in the
for() clause). Yet these two parameters are used by a few drivers, and this
can be considered misuse or at least bad practice.

Now that the kernel uses C11 to build, these two parameters can be avoided
by declaring them internally, thus changing this pattern:

  struct property *prop;
  const __be32 *p;
  u32 val;

  of_property_for_each_u32(np, "xyz", prop, p, val) { ... }

to this:

  u32 val;

  of_property_for_each_u32(np, "xyz", val) { ... }

However two variables cannot be declared in the for clause even with C11,
so declare one struct that contain the two variables we actually need. As
the variables inside this struct are not meant to be used by users of this
macro, give the struct instance the noticeable name "_it" so it is visible
during code reviews, helping to avoid new code to use it directly.

Most usages are trivially converted as they do not use those two
parameters, as expected. The non-trivial cases are:

 - drivers/clk/clk.c, of_clk_get_parent_name(): easily doable anyway
 - drivers/clk/clk-si5351.c, si5351_dt_parse(): this is more complex as the
   checks had to be replicated in a different way, making code more verbose
   and somewhat uglier, but I refrained from a full rework to keep as much
   of the original code untouched having no hardware to test my changes

All the changes have been build tested. The few for which I have the
hardware have been runtime-tested too.

acc5965b9f Char/Misc and other driver changes for 6.11-rc1 
Here is the "big" set of char/misc and other driver subsystem changes
 for 6.11-rc1.  Nothing major in here, just loads of new drivers and
 updates.  Included in here are:
   - IIO api updates and new drivers added
   - wait_interruptable_timeout() api cleanups for some drivers
   - MODULE_DESCRIPTION() additions for loads of drivers
   - parport out-of-bounds fix
   - interconnect driver updates and additions
   - mhi driver updates and additions
   - w1 driver fixes
   - binder speedups and fixes
   - eeprom driver updates
   - coresight driver updates
   - counter driver update
   - new misc driver additions
   - other minor api updates
 
 All of these, EXCEPT for the final Kconfig build fix for 32bit systems,
 have been in linux-next for a while with no reported issues.  The
 Kconfig fixup went in 29 hours ago, so might have missed the latest
 linux-next, but was acked by everyone involved.

 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

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.

f08d4bdad6 bus: mhi: host: pci_generic: Use unique 'mhi_pci_dev_info' for product families 
Currently, a single 'mhi_pci_dev_info' is shared across different product
families. Even though it makes the device functional, it misleads the users
by sharing the common product name.

For instance, below message will be printed for Foxconn SDX62 modem during
boot:

"MHI PCI device found: foxconn-sdx65"

But this is quite misleading to the users since the actual modem plugged in
could be 'T99W373' which is based on SDX62.

So fix this issue by using a unique 'mhi_pci_dev_info' for product
families. This allows us to specify a unique product name for each product
family. Also, once this name is exposed to client drivers, they may use
this name to identify the modems and use any modem specific configuration.

Modems of unknown product families are not impacted by this change.

c7d0b2db5b bus: mhi: ep: Do not allocate memory for MHI objects from DMA zone 
MHI endpoint stack accidentally started allocating memory for objects from
DMA zone since commit 62210a26cd ("bus: mhi: ep: Use slab allocator
where applicable"). But there is no real need to allocate memory from this
naturally limited DMA zone. This also causes the MHI endpoint stack to run
out of memory while doing high bandwidth transfers.

So let's switch over to normal memory.

2c92ca849f tracing/treewide: Remove second parameter of __assign_str() 
With the rework of how the __string() handles dynamic strings where it
saves off the source string in field in the helper structure[1], the
assignment of that value to the trace event field is stored in the helper
value and does not need to be passed in again.

This means that with:

  __string(field, mystring)

Which use to be assigned with __assign_str(field, mystring), no longer
needs the second parameter and it is unused. With this, __assign_str()
will now only get a single parameter.

There's over 700 users of __assign_str() and because coccinelle does not
handle the TRACE_EVENT() macro I ended up using the following sed script:

  git grep -l __assign_str | while read a ; do
      sed -e 's/\(__assign_str([^,]*[^ ,]\) *,[^;]*/\1)/' $a > /tmp/test-file;
      mv /tmp/test-file $a;
  done

I then searched for __assign_str() that did not end with ';' as those
were multi line assignments that the sed script above would fail to catch.

Note, the same updates will need to be done for:

  __assign_str_len()
  __assign_rel_str()
  __assign_rel_str_len()

I tested this with both an allmodconfig and an allyesconfig (build only for both).

1b294a1f35 Networking changes for 6.10. 
Core & protocols
 ----------------
 
  - Complete rework of garbage collection of AF_UNIX sockets.
    AF_UNIX is prone to forming reference count cycles due to fd passing
    functionality. New method based on Tarjan's Strongly Connected Components
    algorithm should be both faster and remove a lot of workarounds
    we accumulated over the years.
 
  - Add TCP fraglist GRO support, allowing chaining multiple TCP packets
    and forwarding them together. Useful for small switches / routers which
    lack basic checksum offload in some scenarios (e.g. PPPoE).
 
  - Support using SMP threads for handling packet backlog i.e. packet
    processing from software interfaces and old drivers which don't
    use NAPI. This helps move the processing out of the softirq jumble.
 
  - Continue work of converting from rtnl lock to RCU protection.
    Don't require rtnl lock when reading: IPv6 routing FIB, IPv6 address
    labels, netdev threaded NAPI sysfs files, bonding driver's sysfs files,
    MPLS devconf, IPv4 FIB rules, netns IDs, tcp metrics, TC Qdiscs,
    neighbor entries, ARP entries via ioctl(SIOCGARP), a lot of the link
    information available via rtnetlink.
 
  - Small optimizations from Eric to UDP wake up handling, memory accounting,
    RPS/RFS implementation, TCP packet sizing etc.
 
  - Allow direct page recycling in the bulk API used by XDP, for +2% PPS.
 
  - Support peek with an offset on TCP sockets.
 
  - Add MPTCP APIs for querying last time packets were received/sent/acked,
    and whether MPTCP "upgrade" succeeded on a TCP socket.
 
  - Add intra-node communication shortcut to improve SMC performance.
 
  - Add IPv6 (and IPv{4,6}-over-IPv{4,6}) support to the GTP protocol driver.
 
  - Add HSR-SAN (RedBOX) mode of operation to the HSR protocol driver.
 
  - Add reset reasons for tracing what caused a TCP reset to be sent.
 
  - Introduce direction attribute for xfrm (IPSec) states.
    State can be used either for input or output packet processing.
 
 Things we sprinkled into general kernel code
 --------------------------------------------
 
  - Add bitmap_{read,write}(), bitmap_size(), expose BYTES_TO_BITS().
    This required touch-ups and renaming of a few existing users.
 
  - Add Endian-dependent __counted_by_{le,be} annotations.
 
  - Make building selftests "quieter" by printing summaries like
    "CC object.o" rather than full commands with all the arguments.
 
 Netfilter
 ---------
 
  - Use GFP_KERNEL to clone elements, to deal better with OOM situations
    and avoid failures in the .commit step.
 
 BPF
 ---
 
  - Add eBPF JIT for ARCv2 CPUs.
 
  - Support attaching kprobe BPF programs through kprobe_multi link in
    a session mode, meaning, a BPF program is attached to both function entry
    and return, the entry program can decide if the return program gets
    executed and the entry program can share u64 cookie value with return
    program. "Session mode" is a common use-case for tetragon and bpftrace.
 
  - Add the ability to specify and retrieve BPF cookie for raw tracepoint
    programs in order to ease migration from classic to raw tracepoints.
 
  - Add an internal-only BPF per-CPU instruction for resolving per-CPU
    memory addresses and implement support in x86, ARM64 and RISC-V JITs.
    This allows inlining functions which need to access per-CPU state.
 
  - Optimize x86 BPF JIT's emit_mov_imm64, and add support for various
    atomics in bpf_arena which can be JITed as a single x86 instruction.
    Support BPF arena on ARM64.
 
  - Add a new bpf_wq API for deferring events and refactor process-context
    bpf_timer code to keep common code where possible.
 
  - Harden the BPF verifier's and/or/xor value tracking.
 
  - Introduce crypto kfuncs to let BPF programs call kernel crypto APIs.
 
  - Support bpf_tail_call_static() helper for BPF programs with GCC 13.
 
  - Add bpf_preempt_{disable,enable}() kfuncs in order to allow a BPF
    program to have code sections where preemption is disabled.
 
 Driver API
 ----------
 
  - Skip software TC processing completely if all installed rules are
    marked as HW-only, instead of checking the HW-only flag rule by rule.
 
  - Add support for configuring PoE (Power over Ethernet), similar to
    the already existing support for PoDL (Power over Data Line) config.
 
  - Initial bits of a queue control API, for now allowing a single queue
    to be reset without disturbing packet flow to other queues.
 
  - Common (ethtool) statistics for hardware timestamping.
 
 Tests and tooling
 -----------------
 
  - Remove the need to create a config file to run the net forwarding tests
    so that a naive "make run_tests" can exercise them.
 
  - Define a method of writing tests which require an external endpoint
    to communicate with (to send/receive data towards the test machine).
    Add a few such tests.
 
  - Create a shared code library for writing Python tests. Expose the YAML
    Netlink library from tools/ to the tests for easy Netlink access.
 
  - Move netfilter tests under net/, extend them, separate performance tests
    from correctness tests, and iron out issues found by running them
    "on every commit".
 
  - Refactor BPF selftests to use common network helpers.
 
  - Further work filling in YAML definitions of Netlink messages for:
    nftables, team driver, bonding interfaces, vlan interfaces, VF info,
    TC u32 mark, TC police action.
 
  - Teach Python YAML Netlink to decode attribute policies.
 
  - Extend the definition of the "indexed array" construct in the specs
    to cover arrays of scalars rather than just nests.
 
  - Add hyperlinks between definitions in generated Netlink docs.
 
 Drivers
 -------
 
  - Make sure unsupported flower control flags are rejected by drivers,
    and make more drivers report errors directly to the application rather
    than dmesg (large number of driver changes from Asbjørn Sloth Tønnesen).
 
  - Ethernet high-speed NICs:

      - support ring reset using the queue control API

      - expose flow hash from RSS to XDP
      - per-queue statistics
      - add selftests

     situations and avoid failures in the .commit step.

  BPF:

   - Add eBPF JIT for ARCv2 CPUs.

   - Support attaching kprobe BPF programs through kprobe_multi link in
     a session mode, meaning, a BPF program is attached to both function
     entry and return, the entry program can decide if the return
     program gets executed and the entry program can share u64 cookie
     value with return program. "Session mode" is a common use-case for
     tetragon and bpftrace.

   - Add the ability to specify and retrieve BPF cookie for raw
     tracepoint programs in order to ease migration from classic to raw
     tracepoints.

   - Add an internal-only BPF per-CPU instruction for resolving per-CPU
     memory addresses and implement support in x86, ARM64 and RISC-V
     JITs. This allows inlining functions which need to access per-CPU
     state.

   - Optimize x86 BPF JIT's emit_mov_imm64, and add support for various
     atomics in bpf_arena which can be JITed as a single x86
     instruction. Support BPF arena on ARM64.

   - Add a new bpf_wq API for deferring events and refactor
     process-context bpf_timer code to keep common code where possible.

   - Harden the BPF verifier's and/or/xor value tracking.

   - Introduce crypto kfuncs to let BPF programs call kernel crypto
     APIs.

   - Support bpf_tail_call_static() helper for BPF programs with GCC 13.

   - Add bpf_preempt_{disable,enable}() kfuncs in order to allow a BPF
     program to have code sections where preemption is disabled.

  Driver API:

   - Skip software TC processing completely if all installed rules are
     marked as HW-only, instead of checking the HW-only flag rule by
     rule.

   - Add support for configuring PoE (Power over Ethernet), similar to
     the already existing support for PoDL (Power over Data Line)
     config.

   - Initial bits of a queue control API, for now allowing a single
     queue to be reset without disturbing packet flow to other queues.

   - Common (ethtool) statistics for hardware timestamping.

  Tests and tooling:

   - Remove the need to create a config file to run the net forwarding
     tests so that a naive "make run_tests" can exercise them.

   - Define a method of writing tests which require an external endpoint
     to communicate with (to send/receive data towards the test
     machine). Add a few such tests.

   - Create a shared code library for writing Python tests. Expose the
     YAML Netlink library from tools/ to the tests for easy Netlink
     access.

   - Move netfilter tests under net/, extend them, separate performance
     tests from correctness tests, and iron out issues found by running
     them "on every commit".

   - Refactor BPF selftests to use common network helpers.

   - Further work filling in YAML definitions of Netlink messages for:
     nftables, team driver, bonding interfaces, vlan interfaces, VF
     info, TC u32 mark, TC police action.

   - Teach Python YAML Netlink to decode attribute policies.

   - Extend the definition of the "indexed array" construct in the specs
     to cover arrays of scalars rather than just nests.

   - Add hyperlinks between definitions in generated Netlink docs.

  Drivers:

   - Make sure unsupported flower control flags are rejected by drivers,
     and make more drivers report errors directly to the application
     rather than dmesg (large number of driver changes from Asbjørn
     Sloth Tønnesen).

   - Ethernet high-speed NICs:
      - Broadcom (bnxt):
         - support multiple RSS contexts and steering traffic to them
         - support XDP metadata
         - make page pool allocations more NUMA aware
      - Intel (100G, ice, idpf):
         - extract datapath code common among Intel drivers into a library
         - use fewer resources in switchdev by sharing queues with the PF
         - add PFCP filter support
         - add Ethernet filter support
         - use a spinlock instead of HW lock in PTP clock ops
         - support 5 layer Tx scheduler topology
      - nVidia/Mellanox:
         - 800G link modes and 100G SerDes speeds
         - per-queue IRQ coalescing configuration
      - Marvell Octeon:
         - support offloading TC packet mark action

   - Ethernet NICs consumer, embedded and virtual:
      - stop lying about skb->truesize in USB Ethernet drivers, it
        messes up TCP memory calculations
      - Google cloud vNIC:
         - support changing ring size via ethtool
         - support ring reset using the queue control API
      - VirtIO net:
         - expose flow hash from RSS to XDP
         - per-queue statistics
         - add selftests
      - Synopsys (stmmac):
         - support controllers which require an RX clock signal from the
           MII bus to perform their hardware initialization
      - TI:
         - icssg_prueth: support ICSSG-based Ethernet on AM65x SR1.0 devices
         - icssg_prueth: add SW TX / RX Coalescing based on hrtimers

48f98496b1 bus: mhi: host: pci_generic: Add generic edl_trigger to allow devices to enter EDL mode 
Some of the MHI modems like SDX65 based ones are capable of entering the
EDL mode as per the standard triggering mechanism defined in the MHI spec
v1.2. So let's add a common mhi_pci_generic_edl_trigger() function that
triggers the EDL mode in the device when user writes to the
/sys/bus/mhi/devices/.../trigger_edl file.

As per the spec, the EDL mode can be triggered by writing a cookie to the
EDL doorbell register and then resetting the device.

Devices supporting this standard way of entering EDL mode can set the
mhi_pci_dev_info::edl_trigger flag.

Some controllers may want to access a specific doorbell register. Hence add
a new API that reads the CHDBOFF register and returns the offset of the

Add sysfs entry to allow users of MHI bus to force device to enter EDL
(Emergency Download) mode to download the device firmware. Since there is
no guarantee that all the devices will support EDL mode, the sysfs entry
is kept as an optional one and will appear only for the supported devices.

Controllers supporting the EDL mode are expected to provide edl_trigger()

We are wrongly checking SYSC_QUIRK_NO_RESET_ON_INIT flag in sysc_reset(),
it can be called also after init from sysc_reinit_module(). Let's move
the check to the init code in preparation for adding reset control support
in the future.

Note that this change is not needed as a fix as there are no known issues
caused by it currently.

5c9668cfc6 firewall: introduce stm32_firewall framework 
Introduce a STM32 firewall framework that offers to firewall consumers
different firewall services such as the ability to check their access
rights against their firewall controller(s).

The STM32 firewall framework offers a generic API for STM32 firewall
controllers that is defined in their drivers to best fit the
specificity of each firewall.

There are various types of firewalls:
-Peripheral firewalls that filter accesses to peripherals
-Memory firewalls that filter accesses to memories or memory regions
-No type for undefined type of firewall

813e0ae613 bus: mhi: host: Add mhi_power_down_keep_dev() API to support system suspend/hibernation 
Currently, ath11k fails to resume from system suspend/hibernation on some
the x86 host machines with below error message:

```
ath11k_pci 0000:06:00.0: timeout while waiting for restart complete
```

This happens because, ath11k powers down the MHI stack during suspend and
that leads to destruction of the struct device associated with the MHI
channels. And during resume, ath11k calls calling mhi_sync_power_up() to
power up the MHI subsystem and that eventually calls the driver framework's
device_add() API from mhi_create_devices(). But the PM framework blocks the
struct device creation during device_add() and this leads to probe deferral
as below:

```
mhi mhi0_IPCR: Driver qcom_mhi_qrtr force probe deferral
```

The reason for deferring device creation during resume is explained in
dpm_prepare():

        /*
         * It is unsafe if probing of devices will happen during suspend or
         * hibernation and system behavior will be unpredictable in this
         * case. So, let's prohibit device's probing here and defer their
         * probes instead. The normal behavior will be restored in
         * dpm_complete().
         */

Due to the device probe deferral, qcom_mhi_qrtr_probe() API is not getting
called during resume and thus MHI channels are not prepared. So this blocks
the QMI messages from being transferred between ath11k and firmware,
resulting in a firmware initialization failure.

After consulting with Rafael, it was decided to not destroy the struct
device for the MHI channels during system suspend/hibernation because the
device is bound to appear again during resume.

So to achieve this, a new API called mhi_power_down_keep_dev() is
introduced for MHI controllers to keep the struct device when required.
This API is similar to the existing mhi_power_down() API, except that it
keeps the struct device associated with MHI channels instead of destroying
them.

Here is the big set of char/misc and a number of other driver subsystem
 updates for 6.9-rc1.  Included in here are:
   - IIO driver updates, loads of new ones and evolution of existing ones
   - coresight driver updates
   - const cleanups for many driver subsystems
   - speakup driver additions
   - platform remove callback void cleanups
   - mei driver updates
   - mhi driver updates
   - cdx driver updates for MSI interrupt handling
   - nvmem driver updates
   - other smaller driver updates and cleanups, full details in the

 All of these have been in linux-next for a long time with no reported
 issue, other than a build warning with some older versions of gcc for a
 speakup driver, fix for that will come in a few days when I catch up
 with my pending patch queues.

The build warning hits clang and is a gcc (and C23) extension, and is
fixed up in the merge.

78c3925c04 ARM: late SoC changes for 6.9 
These are changes that for some reason ended up not making it into the
 first four branches but that should still make it into 6.9:
 
  - A rework of the omap clock support that touches both drivers and
    device tree files
 
  - The reset controller branch changes that had a dependency on late
    bugfixes. Merging them here avoids a backmerge of 6.8-rc5 into the
    drivers branch
 
  - The RISC-V/starfive, RISC-V/microchip and ARM/Broadcom devicetree
    changes that got delayed and needed some extra time in linux-next
    for wider testing.

core can properly handle constant struct device_type. Move the

a52354173b bus: mhi: host: Change the trace string for the userspace tools mapping 
User space tools can't map strings if we use directly, as the string
address is internal to kernel.

So add trace point strings for the user space tools to map strings
properly.

f0397e27d1 Revert "bus: mhi: core: Add support for reading MHI info from device" 
This reverts commit 3316ab2b45.

The MHI spec owner pointed out that the SOC_HW_VERSION register is part
of the BHIe segment, and only valid on devices which implement BHIe.
Only a small subset of MHI devices implement BHIe so blindly accessing
the register for all devices is not correct. Also, since the BHIe
segment offset is not used when accessing the register, any
implementation which moves the BHIe segment will result in accessing
some other register.  We've seen that accessing this register on AIC100
which does not support BHIe can result in initialization failures.

We could try to put checks into the code to address these issues, but in
the roughly 4 years this functionality has existed, no one has used it.
Easier to drop this dead code and address the issues if anyone comes up
with a real world use for it.
