RISC-V Patches for the 6.11 Merge Window, Part 2
* Support for NUMA (via SRAT and SLIT), console output (via SPCR), and cache info (via PPTT) on ACPI-based systems. * The trap entry/exit code no longer breaks the return address stack predictor on many systems, which results in an improvement to trap latency. * Support for HAVE_ARCH_STACKLEAK. * The sv39 linear map has been extended to support 128GiB mappings. * The frequency of the mtime CSR is now visible via hwprobe. -----BEGIN PGP SIGNATURE----- iQJHBAABCAAxFiEEKzw3R0RoQ7JKlDp6LhMZ81+7GIkFAmaj2EYTHHBhbG1lckBk YWJiZWx0LmNvbQAKCRAuExnzX7sYiVG3D/9kNHTI09iPDJd6fTChE3cpMxy7xXXE URX3Avu+gYsJmIbYyg4RnQ8FGFN7icKBCrQqs7JmLliU0NU+YMcCcjsJA2QaivbD VAlaex1qNcvNGteHrpbqhr3Zs4zw8GlBkB3KFTLyPAp61bybGo0a/A5ONJ7ScQIW RWHewAPgb86cQ0Q34JpO87TqvMM0KMvhQP5dip+olaFjLRBzhXmGFZfHqA80kTWl 0ytYclVCHZMtO/5mnQpuIOVs1IKw9L4wa0sivOQF0iLTqfKDFALa6yZsThHA/w3e JVuBAdQhcPZ3fgO2fUfJPlW16GmRC2/tdiFg5NFw8k4vo7DYBwX55ztPKXqDrJDM 8ah85IeLiPar/A/uHdn6bPjK+aGMuzklKF50r62XXAc2fL8mza1sdvKCVOy2EOLn JyGI9c/10KpvN/DW8g7hPefhvbx4+tCKkFcPqf++VQha6W8cQdCKi+Li0Pm8TTnp XPQjIvSlDDG1Pl4ofgBSFoyB8pkBXNzvv8NZp+YYtnqSOLAKaZuP+KwA8TwHdvGM pdCXcL3KHiLy4/pJWEoNTutD0mbJ7PUIb2P/KkjqYDgp4F1n0Hg+/aeSIp+7a4Pv yTBctIGxrlriQMIdtWCR8tyhcPP4pDpGYkW0K15EE16G0NK0fjD89LEXYqT6ae2R C0QgiwnVe/eopg== =zeUn -----END PGP SIGNATURE----- Merge tag 'riscv-for-linus-6.11-mw2' of git://git.kernel.org/pub/scm/linux/kernel/git/riscv/linux Pull more RISC-V updates from Palmer Dabbelt: - Support for NUMA (via SRAT and SLIT), console output (via SPCR), and cache info (via PPTT) on ACPI-based systems. - The trap entry/exit code no longer breaks the return address stack predictor on many systems, which results in an improvement to trap latency. - Support for HAVE_ARCH_STACKLEAK. - The sv39 linear map has been extended to support 128GiB mappings. - The frequency of the mtime CSR is now visible via hwprobe. * tag 'riscv-for-linus-6.11-mw2' of git://git.kernel.org/pub/scm/linux/kernel/git/riscv/linux: (21 commits) RISC-V: Provide the frequency of time CSR via hwprobe riscv: Extend sv39 linear mapping max size to 128G riscv: enable HAVE_ARCH_STACKLEAK riscv: signal: Remove unlikely() from WARN_ON() condition riscv: Improve exception and system call latency RISC-V: Select ACPI PPTT drivers riscv: cacheinfo: initialize cacheinfo's level and type from ACPI PPTT riscv: cacheinfo: remove the useless input parameter (node) of ci_leaf_init() RISC-V: ACPI: Enable SPCR table for console output on RISC-V riscv: boot: remove duplicated targets line trace: riscv: Remove deprecated kprobe on ftrace support riscv: cpufeature: Extract common elements from extension checking riscv: Introduce vendor variants of extension helpers riscv: Add vendor extensions to /proc/cpuinfo riscv: Extend cpufeature.c to detect vendor extensions RISC-V: run savedefconfig for defconfig RISC-V: hwprobe: sort EXT_KEY()s in hwprobe_isa_ext0() alphabetically ACPI: NUMA: replace pr_info with pr_debug in arch_acpi_numa_init ACPI: NUMA: change the ACPI_NUMA to a hidden option ACPI: NUMA: Add handler for SRAT RINTC affinity structure ... |

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.

Merge patch series "Add ACPI NUMA support for RISC-V"
Haibo Xu <haibo1.xu@intel.com> says:
This patch series enable RISC-V ACPI NUMA support which was based on
the recently approved ACPI ECR[1].
Patch 1/4 add RISC-V specific acpi_numa.c file to parse NUMA information
from SRAT and SLIT ACPI tables.
Patch 2/4 add the common SRAT RINTC affinity structure handler.
Patch 3/4 change the ACPI_NUMA to a hidden option since it would be selected
by default on all supported platform.
Patch 4/4 replace pr_info with pr_debug in arch_acpi_numa_init() to avoid
potential boot noise on ACPI platforms that are not NUMA.
Based-on: https://github.com/linux-riscv/linux-riscv/tree/for-next
[1] https://drive.google.com/file/d/1YTdDx2IPm5IeZjAW932EYU-tUtgS08tX/view?usp=sharing
Testing:
Since the ACPI AIA/PLIC support patch set is still under upstream review,
hence it is tested using the poll based HVC SBI console and RAM disk.
1) Build latest Qemu with the following patch backported

ACPI: NUMA: replace pr_info with pr_debug in arch_acpi_numa_init
There are lots of ACPI enabled systems that aren't NUMA and If the firmware didn't provide the SRAT/SLIT, then there will be a message "Failed to initialise from firmware" from arch_acpi_numa_init() which adding noise to the boot on all of those kind of systems. Replace the pr_info with pr_debug in arch_acpi_numa_init() to avoid it.

regmap: maple: work around gcc-14.1 false-positive warning
With gcc-14.1, there is a false-postive -Wuninitialized warning in
regcache_maple_drop:
drivers/base/regmap/regcache-maple.c: In function 'regcache_maple_drop':
drivers/base/regmap/regcache-maple.c:113:23: error: 'lower_index' is used uninitialized [-Werror=uninitialized]
113 | unsigned long lower_index, lower_last;
| ^~~~~~~~~~~
drivers/base/regmap/regcache-maple.c:113:36: error: 'lower_last' is used uninitialized [-Werror=uninitialized]
113 | unsigned long lower_index, lower_last;
| ^~~~~~~~~~
I've created a reduced test case to see if this needs to be reported
as a gcc, but it appears that the gcc-14.x branch already has a change
that turns this into a more sensible -Wmaybe-uninitialized warning, so
I ended up not reporting it so far.
The reduced test case also produces a warning for gcc-13 and gcc-12
but I don't see that with the version in the kernel.

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).

spi: Updates for v6.11
There's some quite exciting core work in this release, we've got the
beginnings of support for hardware initiated transfers which is itself
independently useful for optimising fast paths in existing drivers.
We also have a rework of the DMA mapping which allows finer grained
decisions about DMA mapping messages and also helps remove some bodges
that we'd had.
Otherwise it's a fairly quiet release, a few new drivers and features
for existing drivers, together with various cleanups and DT binding
conversions.
One regmap SPI fix made it's way in here too which I should probably
have sent as a regmap fix instead.
- Support for pre-optimising messages, reducing the overhead for
messages that are repeatedly used (eg, reading the interrupt status
from a device). This will also be used for hardware initiated
transfers in future.
- A reworking of how DMA mapping is done, introducing a new helper and
allowing the DMA mapping decision to be done per transfer instead of
per message.
- Support for Atmel SAMA7D64, Freescale LX2160A DSPI and WCH CH341A.

driver core: auxiliary bus: show auxiliary device IRQs
PCI subfunctions (SF) are anchored on the auxiliary bus. PCI physical and virtual functions are anchored on the PCI bus. The irq information of each such function is visible to users via sysfs directory "msi_irqs" containing files for each irq entry. However, for PCI SFs such information is unavailable. Due to this users have no visibility on IRQs used by the SFs. Secondly, an SF can be multi function device supporting rdma, netdevice and more. Without irq information at the bus level, the user is unable to view or use the affinity of the SF IRQs. Hence to match to the equivalent PCI PFs and VFs, add "irqs" directory, for supporting auxiliary devices, containing file for each irq entry. For example: $ ls /sys/bus/auxiliary/devices/mlx5_core.sf.1/irqs/ 50 51 52 53 54 55 56 57 58 Cc: Simon Horman <horms@kernel.org> Reviewed-by: Przemek Kitszel <przemyslaw.kitszel@intel.com> Reviewed-by: Parav Pandit <parav@nvidia.com> Reviewed-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Signed-off-by: Shay Drory <shayd@nvidia.com> Signed-off-by: Saeed Mahameed <saeedm@nvidia.com> --- v9-v10: - remove Przemek RB - add name field to auxiliary_irq_info (Greg and Przemek) - handle bogus IRQ in auxiliary_device_sysfs_irq_remove (Greg) v8-v9: - add Przemek RB - use guard() in auxiliary_irq_dir_prepare (Paolo) v7-v8: - use cleanup.h for info and name fields (Greg) - correct error flow in auxiliary_irq_dir_prepare (Przemek) - add documentation for new fields of auxiliary_device (Simon) v6-v7: - dynamically creating irqs directory when first irq file created (Greg) - removed irqs flag and simplified the dev_add() API (Greg) - move sysfs related new code to a new auxiliary_sysfs.c file (Greg) v5-v6: - removed concept of shared and exclusive and hence global xarray (Greg) v4-v5: - restore global mutex and replace refcount_t with simple integer (Greg) v3->4: - remove global mutex (Przemek) v2->v3: - fix function declaration in case SYSFS isn't defined v1->v2: - move #ifdefs from drivers/base/auxiliary.c to include/linux/auxiliary_bus.h (Greg) - use EXPORT_SYMBOL_GPL instead of EXPORT_SYMBOL (Greg) - Fix kzalloc(ref) to kzalloc(*ref) (Simon) - Add return description in auxiliary_device_sysfs_irq_add() kdoc (Simon) - Fix auxiliary_irq_mode_show doc (kernel test boot) |

It is helpful if multiple non- sequential registers need to be read in a single operation which would otherwise have to be mutex protected.

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. Cc: Rafael J.

cpumask: Add enabled cpumask for present CPUs that can be brought online
The 'offline' file in sysfs shows all offline CPUs, including those that aren't present. User-space is expected to remove not-present CPUs from this list to learn which CPUs could be brought online. CPUs can be present but not-enabled. These CPUs can't be brought online until the firmware policy changes, which comes with an ACPI notification that will register the CPUs. With only the offline and present files, user-space is unable to determine which CPUs it can try to bring online. Add a new CPU mask that shows this based on all the registered CPUs.

drivers: core: synchronize really_probe() and dev_uevent()
Synchronize the dev->driver usage in really_probe() and dev_uevent().
These can run in different threads, what can result in the following
race condition for dev->driver uninitialization:
Thread #1:
==========
really_probe() {
...
probe_failed:
...
device_unbind_cleanup(dev) {
...
dev->driver = NULL; // <= Failed probe sets dev->driver to NULL
...
}
...
}
Thread #2:
==========
dev_uevent() {
...
if (dev->driver)
// If dev->driver is NULLed from really_probe() from here on,
// after above check, the system crashes
add_uevent_var(env, "DRIVER=%s", dev->driver->name);
...
}
really_probe() holds the lock, already. So nothing needs to be done
there. dev_uevent() is called with lock held, often, too. But not
always. What implies that we can't add any locking in dev_uevent()
itself. So fix this race by adding the lock to the non-protected
path. This is the path where above race is observed:
dev_uevent+0x235/0x380
uevent_show+0x10c/0x1f0 <= Add lock here
dev_attr_show+0x3a/0xa0
sysfs_kf_seq_show+0x17c/0x250
kernfs_seq_show+0x7c/0x90
seq_read_iter+0x2d7/0x940
kernfs_fop_read_iter+0xc6/0x310
vfs_read+0x5bc/0x6b0
ksys_read+0xeb/0x1b0
__x64_sys_read+0x42/0x50
x64_sys_call+0x27ad/0x2d30
do_syscall_64+0xcd/0x1d0
entry_SYSCALL_64_after_hwframe+0x77/0x7f
Similar cases are reported by syzkaller in
https://syzkaller.appspot.com/bug?extid=ffa8143439596313a85a
But these are regarding the *initialization* of dev->driver
dev->driver = drv;
As this switches dev->driver to non-NULL these reports can be considered
to be false-positives (which should be "fixed" by this commit, as well,
though).
The same issue was reported and tried to be fixed back in 2015 in
https://lore.kernel.org/lkml/1421259054-2574-1-git-send-email-a.sangwan@samsung.com/
already.

platform: Make platform_driver::remove() return void
struct platform_driver::remove returning an integer made driver authors
expect that returning an error code was proper error handling. However
the driver core ignores the error and continues to remove the device
because there is nothing the core could do anyhow and reentering the
remove callback again is only calling for trouble.
To prevent such wrong assumptions, change the return type of the remove
callback to void. This was prepared by introducing an alternative remove
callback returning void and converting all drivers to that. So .remove()
can be changed without further changes in drivers.
This corresponds to step b) of the plan outlined in commit

regmap-i2c: Subtract reg size from max_write
Currently, when an adapter defines a max_write_len quirk, the data will be chunked into data sizes equal to the max_write_len quirk value. But the payload will be increased by the size of the register address before transmission. The resulting value always ends up larger than the limit set by the quirk. Avoid this error by setting regmap's max_write to the quirk's max_write_len minus the number of bytes for the register and padding. This allows the chunking to work correctly for this limited case without impacting other use-cases.

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).

regmap: kunit: Fix array overflow in stride() test
Force the max_register of the test regmap to be one register longer than the number of test registers, to prevent an array overflow in the test loop. The test defines num_reg_defaults = 6. With 6 registers and stride == 2 the valid register addresses would be 0, 2, 4, 6, 8, 10. However the loop checks attempting to access the odd address, so on the final register it accesses address 11, and it writes entry [11] of the read/written arrays. Originally this worked because the max_register of the regmap was hardcoded to be BLOCK_TEST_SIZE (== 12). commit |

powerpc updates for 6.10
- Enable BPF Kernel Functions (kfuncs) in the powerpc BPF JIT.
- Allow per-process DEXCR (Dynamic Execution Control Register) settings via
prctl, notably NPHIE which controls hashst/hashchk for ROP protection.
- Install powerpc selftests in sub-directories. Note this changes the way
run_kselftest.sh needs to be invoked for powerpc selftests.
- Change fadump (Firmware Assisted Dump) to better handle memory add/remove.
- Add support for passing additional parameters to the fadump kernel.
- Add support for updating the kdump image on CPU/memory add/remove events.
- Other small features, cleanups and fixes.

Merge tag 'powerpc-6.10-1' of git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux
Pull powerpc updates from Michael Ellerman:
- Enable BPF Kernel Functions (kfuncs) in the powerpc BPF JIT.
- Allow per-process DEXCR (Dynamic Execution Control Register) settings
via prctl, notably NPHIE which controls hashst/hashchk for ROP
protection.
- Install powerpc selftests in sub-directories. Note this changes the
way run_kselftest.sh needs to be invoked for powerpc selftests.
- Change fadump (Firmware Assisted Dump) to better handle memory
add/remove.
- Add support for passing additional parameters to the fadump kernel.
- Add support for updating the kdump image on CPU/memory add/remove
events.
- Other small features, cleanups and fixes.

arch/topology: Fix variable naming to avoid shadowing
Using 'hw_pressure' for local variable name is confusing in regard to the
per-CPU 'hw_pressure' variable that uses the same name:
include/linux/arch_topology.h:DECLARE_PER_CPU(unsigned long, hw_pressure);
... which puts it into a global scope for all code that includes
<linux/topology.h>, shadowing the local variable.
Rename it to avoid compiler confusion & Sparse warnings.

driver core: Add device_show_string() helper for sysfs attributes
For drivers wishing to expose an unsigned long, int or bool at a static memory location in sysfs, the driver core provides ready-made helpers such as device_show_ulong() to be used as ->show() callback. Some drivers need to expose a string and so far they all provide their own ->show() implementation. arch/powerpc/perf/hv-24x7.c went so far as to create a device_show_string() helper but kept it private. Make it public for reuse by other drivers. The pattern seems to be sufficiently frequent to merit a public helper. Add a DEVICE_STRING_ATTR_RO() macro in line with the existing DEVICE_ULONG_ATTR() and similar macros to ease declaration of string attributes.

sched/cpufreq: Rename arch_update_thermal_pressure() => arch_update_hw_pressure()
Now that cpufreq provides a pressure value to the scheduler, rename arch_update_thermal_pressure into HW pressure to reflect that it returns a pressure applied by HW (i.e. with a high frequency change) and not always related to thermal mitigation but also generated by max current limitation as an example. Such high frequency signal needs filtering to be smoothed and provide an value that reflects the average available capacity into the scheduler time scale.

IIO: 1st set of new device support, features and cleanup for 6.10
The Analog Device team (Paul Cercueil and Nuno Sa) have been working on
improving high speed device handling. They have had some support in their
own tree for many years, so it is great to see them bring it to upstream.
Some of that is seen here, with the first output device using the
IIO dmaengine infrastructure and a new DAC backend FPGA IP driver.
This makes use of a new set of interfaces to allow backend and
front end driver communication in a fashion that in theory at least
allows for a single driver for a given ADC / DAC independent of
the IP to which is being used to deal with the data bus and DMA aspects
of working with these devices. It is early days for this new
generic way of handling split devices, but as it's kernel internals only
we can merrily change anything about it as a wider diversity of devices
show up and we get a better feel for what works.
Alongside the usual set of new drivers and features we have
the automatic cleanup of fwnode_handle_put() which didn't quite make
it in last cycle. The equivalent DT version was merged by Rob Herring
via the DT binding tree and one patch using that in IIO can also be
found in this pull request. Rob has been making extensive use of that
infrastructure in the DT core which is good to see and provides more
evidence this basic approach is useful.
In some cases, the IIO driver was converted over from DT only to
using the generic firmware description handling of property.h
including using the new macros. The general preference for IIO
is to use this more generic handling where possible - a bunch of other
drivers have been converted this cycle as well.
New device support
==================
adi,ad7173
- New driver supporting AD7172-2, AD7172-4 AD7173-9, AD7175-2, AD7175-8,
AD7176-2 and AD7177-2 ADCs.
- Follow up fix for an accidental use of logic not instead of bitwise.
adi,ad7944
- New driver supporting AD7944, AD7985 and AD7986 pin compatible ADCs.
- Later patch added use of new spi_optimize_message() to reduce overheads
of setting up a reused message.
- Additional changes later in series reduced code duplication.
adi,ad9739a RF DAC
- New driver for this 14-bit 2.5 GSPS DAC via an LVDS interface.
adi,axi-dac
- Support for this FPGA IP used to send data to high performance DACs over
an interface such as JESD204B/C or parallel interfaces. Used in
conjunction with a DAC driver. The initial user is the ad9739a.
The dmaengine-buffer needed various changes to make it bidirectional.
avago,apds9306
- New driver for this ambient light sensor.
- Fix much later in this pull for an off by 1 error.
New device IDs
==============
For these at most an ID and a instance of chip specific data was needed.
Always nice to see manufacturers sticking to an existing software interface
for new parts.
allwinner,sun20i
- Add support for h616.
invensense,mpu6050
- Add support for ICM42688
maxim,max30102
- Add compatible for MAX30101
ti,dac5571
- Add compatible for DAC081C081
General
=======
fwnode_handle
- Support for cleanup.h based __free(fwnode_handle)
- Loop macro using this for looping over child nodes without needing to
call fwnode_handle_put() in ever early exit from the loop.
- Used in:
* adi,ad3552r
* adi,ad4130
* adi,ad5770r

* adi,ad7124
* adi,ad7292
* freescale,fsl-imx25-gcq
- Other conversions to fwnode where the new cleanup handling isn't useful
* adi,ad7192
* avia,hx711
* freescale,mma8452
* nxp,fxls8962af
* st,spear
* ti,twl4030
Features
========
adi,adxl345
- Support SPI_3WIRE mode.
adi,ad9944
- Support 3-wire mode, note this isn't normal 3-wire SPI (unlike the
adxl345 change above), but rather a wiring scheme where the SPI
chip select is used to trigger conversions rather than using a
separate pin.
- Add some device specific documentation, mostly around the various wiring
schemes.
invensense,mpu6050
- Add Wake on Motion support as an IIO event and as a wake-up source.
linear,ltc2983
- Add vdd-supply.
ti,hdc3020
- Add power management using trigger on demand mode and adding suspend and
resume handling.
- Use reset GPIO if available.
Cleanup and fixes
================
iio core
- Use the various autocleanup and lock guards from cleanup.h to simplify
the IIO core.
- Don't set the pointer used for iio_priv() if it is zero sized as that
points beyond the end of the allocation. No driver actually uses it
in that case but good to clean this up.
various drivers
- Drop unnecessary casts of other pointer types to void *
docs
- Add missing ABI entry for in_temp_input.
adi,adx345
- General cleanup prior to adding spi-3wire mode.
adi,axi-adc
- Be more flexible and allow minor version changes as these are expected
to be backwards compatible.
avago,apds9300/9600
- Merge near identical bindings. The drivers are quite different, but
the bindings can be shared. The apds9306 binding introduced in this
series uses this shared binding doc as well.
- Add missing vdd-supply
- Update binding to use IRQ_TYPE_LEVEL_LOW instead of 8.
bosch,bmp280
- Organize headers
freescale,fxl-imx25-gcq
- Use devm_ for remaining probe() time setup allowing dropping
of specific error handling and remove() functions.
infineon,dps310
- Fix handling of negative temperatures
- Bring style of other similar calls inline with the form needed
for temperatures
- Ensure error handling of regmap calls is consistent within the driver.
- Simplify scale reading logic.
invensense,mpu6050
- Flip logic in binding to exclude devices without i2c-gate instead
of opting in. The list is expected to be much shorter as all recent
devices support this feature.
honeywell,hsc030pa
- Use spi_read() instead of opening coding.
renesas,rcar
- Use device_for_each_child_of_node_scoped() to remove need to manually
release. Left over from series the rest of which went in during 6.9.
st,ab8500
- Fix naming of function parameters in kernel-doc

ti,hdc3020
- Add power management using trigger on demand mode and adding suspend and
resume handling.
- Use reset GPIO if available.
Cleanup and fixes
================
iio core
- Use the various autocleanup and lock guards from cleanup.h to simplify
the IIO core.
- Don't set the pointer used for iio_priv() if it is zero sized as that
points beyond the end of the allocation. No driver actually uses it
in that case but good to clean this up.
various drivers
- Drop unnecessary casts of other pointer types to void *
docs
- Add missing ABI entry for in_temp_input.
adi,adx345
- General cleanup prior to adding spi-3wire mode.
adi,axi-adc
- Be more flexible and allow minor version changes as these are expected
to be backwards compatible.
avago,apds9300/9600
- Merge near identical bindings. The drivers are quite different, but
the bindings can be shared. The apds9306 binding introduced in this
series uses this shared binding doc as well.
- Add missing vdd-supply
- Update binding to use IRQ_TYPE_LEVEL_LOW instead of 8.
bosch,bmp280
- Organize headers
freescale,fxl-imx25-gcq
- Use devm_ for remaining probe() time setup allowing dropping
of specific error handling and remove() functions.
infineon,dps310
- Fix handling of negative temperatures
- Bring style of other similar calls inline with the form needed
for temperatures
- Ensure error handling of regmap calls is consistent within the driver.
- Simplify scale reading logic.
invensense,mpu6050
- Flip logic in binding to exclude devices without i2c-gate instead
of opting in. The list is expected to be much shorter as all recent
devices support this feature.
honeywell,hsc030pa
- Use spi_read() instead of opening coding.
renesas,rcar
- Use device_for_each_child_of_node_scoped() to remove need to manually
release. Left over from series the rest of which went in during 6.9.
st,ab8500
- Fix naming of function parameters in kernel-doc

regmap: kunit: Fix an NULL vs IS_ERR() check
The kunit_device_register() function returns error pointers, not NULL.
Passing an error pointer to get_device() will lead to an Oops. Also
get_device() returns the same device you passed to it. Fix it! ;)

module: don't ignore sysfs_create_link() failures
The sysfs_create_link() return code is marked as __must_check, but the module_add_driver() function tries hard to not care, by assigning the return code to a variable. When building with 'make W=1', gcc still warns because this variable is only assigned but not used: drivers/base/module.c: In function 'module_add_driver': drivers/base/module.c:36:6: warning: variable 'no_warn' set but not used [-Wunused-but-set-variable] Rework the code to properly unwind and return the error code to the caller. My reading of the original code was that it tries to not fail when the links already exist, so keep ignoring -EEXIST errors. Fixes: |

regmap: kunit: Add cache-drop test with multiple cache blocks
Add a test case for dropping only some cache blocks and leaving others unchanged. The regmap is divided into 8 register ranges, and only 4 of these are written with values. This creates 4 non-contiguous ranges of registers with cached values. One whole range is then dropped, and part of another range. A cache sync is then performed to check that the correct registers were written, and the correct values were written to these registers.

regmap: kunit: Add more cache-sync tests
Extend the testing of cache-sync. - cache_sync() renamed cache_sync_marked_dirty() for clarity of what conditions it is testing. - cache_sync_defaults() renamed cache_sync_defaults_marked_dirty() for clarity. Added code to write the register back to its default value to check that a dirty sync doesn't write out the default value. - Added cache_sync_after_cache_only(). Tests syncing the cache without calling regcache_mark_dirty(). A register written while in cache-only should be written out by regcache_sync(). - Added cache_sync_default_after_cache_only. This is similar to cache_sync_after_cache_only(), but the register is changed to its default value while in cache-only. Because regcache_mark_dirty() was NOT called, regacache_sync() should write out the register.
