Merge tag 'iio-for-6.9a' of git./linux/kernel/git/jic23/iio into char-misc-next

Jonathan writes:

IIO: 1st set of new device support, features and cleanup for 6.9

IIO Backend support
===================

New approach from Nuno Sa to the problem of reuse of drivers with
IIO devices that are actually the combination of a highspeed chip
and an FPGA core handling the data capture and flows. It will hopefully
also apply to some other split designs. The ad9467 and axi-adi drivers
are converted over to this framework.

New device support
==================

adi,admfm2000
- New driver for this dual microwave down converter.
ams,as73211
- Add support for as7331 UV sensor.
richtek,rtq6056
- Add support for related parts RTQ6053 and RTQ6059
st,lsm6dsx
- Add ASM330LHHXG1 accelerometer and gyro support (mainly IDs)
ti,ads1298
- New driver for this medical ADC.

Features
========

tests
- Unit tests for the gain-time-scale helper library.
bosch,bmi088
- I2C support.
bosh,bmi160
- Add 10EC5280 ACPI ID. Used in a number of devices that won't get fixed.
  The ID is actually a PCI ID belonging to realtech. No response was received
  to earlier attempts to notify them of this.
  The manufacturers of some devices have replied to say they will not fix
  this incorrect ID. Add the ID and hope it isn't a problem.
bosch,bmi323
- Add BOSC0200 ACPI ID. Note this is a duplicate of one in the bmc150
  driver (it appears these parts share a windows driver).
  Both drivers perform an ID check that is safe on the other part before
  successfully probing.
hid-sensors-als
- Add color temperature and chromaticity support. Note this is a replacement
  for the series reverted in 6.8 that correctly handles all the potential
  channel combinations.
honeywell,hsc030pa
- Triggered buffer support (after driver cleanup).
honeywell,mprls00025pa
- Improved error handling.
- New DT binding to allow use of part number triplet as provided in data sheet
  to specify equivalent of most of the binding more efficiently.
- SPI support.
memsic,mxc4005
- ACPI ID MDA6655 as seen in the Chuwi Minibook X 2023
ti,hdc3020
- Add threshold event support (after some driver cleanup)
veml,vcnl4000
- Switch to high resolution proximity measurement.

Cleanup
=======
Various minor typo fixes and better use of defines etc.

Treewide
- Stop using ACPI_PTR(). The savings in space are small and not worth
  the complexity of __maybe_unused of ifdef guards.  To avoid use in
  new IIO drivers based on copy and paste, clean it out.
- cleanup.h based handling of iio_device_claim_direct_mode()/
  iio_device_release_direct_mode() using scope_cond_guard().
  In many drivers this is combined with other automated cleanup
  to give maximum simplifications.
  An initial set of drivers are converted over to this infrastructure.

Tools
- Use rewinddir() instead of seekdir() to return to start of file.

core
- Make iio_bus_type constant.

adi,ad16475
- Use irq_get_trigger_type() instead of opencoding.
adi,ad16480
- Use irq_get_trigger_type() instead of opencoding.
adi,ad-sigma-delta
- Avoid overwriting IRQ flags if provided by firmware.
ams,as73211
- Use IIO_VAL_FRACTIONAL for scales to simplify the code and potentially
  improve accuracy.
gts-library
- Use a div64_u64() instead of a loop to do a division.
honeywell,mprls00025pa
- Clean up dt-binding doc.
- Drop defaults when DT binding not providing values. Very unlikely
  these were useful given they were wrong for vast majority of supported
  devices.
- Whitespace cleanup
miramems,da280
- Use i2c_get_match_data() to replace hand rolled ACPI matching code.
semtech,sx9324
- Avoid unnecessary copying of property strings.
st,lsm6dsx
- Improve docs, particularly wrt to making addition of new device
  support less noisy.
st,lsm9ds0
- Use dev_err_probe() in all probe() error handling.
- Improved header includes.
- Tidy up termination of ID tables.
ti,ads1014
- Correct upper bound on PGA (wrong value had no actual impact)
ti,afe4403/4404
- devm_ useage to simplify error handling in probe() and allow() remove to
  be dropped.
voltage-divider
- Add dt-binding for io-channel-cells to allow such a device to be both
  an IIO consumer and IIO producer at the same time.

iio: adc: ad9467: convert to backend framework

Convert the driver to use the new IIO backend framework. The device
functionality is expected to be the same (meaning no added or removed
features).

Also note this patch effectively breaks ABI and that's needed so we can
properly support this device and add needed features making use of the
new IIO framework.

Given the lack of features (and devices supported) in the ad9467 driver
compared with the ADI out of tree version, we don't expect any user of
the upstream driver so no one should notice the ABI breakage. However,
if someone is affected by this, ADI will happily support transitioning
to the backend framework.

iio: add the IIO backend framework

This is a Framework to handle complex IIO aggregate devices.

The typical architecture is to have one device as the frontend device which
can be "linked" against one or multiple backend devices. All the IIO and
userspace interface is expected to be registers/managed by the frontend
device which will callback into the backends when needed (to get/set
some configuration that it does not directly control).

The basic framework interface is pretty simple:
 - Backends should register themselves with @devm_iio_backend_register()
 - Frontend devices should get backends with @devm_iio_backend_get()

dt-bindings: adc: axi-adc: update bindings for backend framework

'adi,adc-dev' is now deprecated and must not be used anymore. Hence,
also remove it from being required.

The reason why it's being deprecated is because the axi-adc CORE is now
an IIO service provider hardware (IIO backends) for consumers to make use
of. Before, the logic with 'adi,adc-dev' was the opposite (it was kind
of consumer referencing other nodes/devices) and that proved to be wrong
and to not scale.

Now, IIO consumers of this hardware are expected to reference it using the
io-backends property. Hence, the new '#io-backend-cells' is being added
so the device is easily identified as a provider.

Add 10EC5280 to bmi160_i2c ACPI IDs to allow binding on some devices

"10EC5280" is used by several manufacturers like Lenovo, GPD, or AYA (and
probably others) in their ACPI table as the ID for the bmi160 IMU. This
means the bmi160_i2c driver won't bind to it, and the IMU is unavailable
to the user. Manufacturers have been approached on several occasions to
try getting a BIOS with a fixed ID, mostly without actual positive
results, and since affected devices are already a few years old, this is
not expected to change. This patch enables using the bmi160_i2c driver for
the bmi160 IMU on these devices.

Here is the relevant extract from the DSDT of a GPD Win Max 2 (AMD 6800U
model) with the latest firmware 1.05 installed. GPD sees this as WONTFIX
with the argument of the device working with the Windows drivers.

Matti Vaittinen [Mon, 15 Jan 2024 14:26:07 +0000 (16:26 +0200)]
iio: test: test gain-time-scale helpers

Some light sensors can adjust both the HW-gain and integration time.
There are cases where adjusting the integration time has similar impact
to the scale of the reported values as gain setting has.

IIO users do typically expect to handle scale by a single writable 'scale'
entry. Driver should then adjust the gain/time accordingly.

It however is difficult for a driver to know whether it should change
gain or integration time to meet the requested scale. Usually it is
preferred to have longer integration time which usually improves
accuracy, but there may be use-cases where long measurement times can be
an issue. Thus it can be preferable to allow also changing the
integration time - but mitigate the scale impact by also changing the gain
underneath. Eg, if integration time change doubles the measured values,
the driver can reduce the HW-gain to half.

The theory of the computations of gain-time-scale is simple. However,
some people (undersigned) got that implemented wrong for more than once.
Hence some gain-time-scale helpers were introduced.

Add some simple tests to verify the most hairy functions.

   - Don't source the VFIO Kconfig twice

   - Fix protected-mode locking order between kvm and vcpus

   - Fix steal-time related sparse warnings

  x86:

   - Cleanup gtod_is_based_on_tsc() to return "bool" instead of an "int"

   - Make a KVM_REQ_NMI request while handling KVM_SET_VCPU_EVENTS if
     and only if the incoming events->nmi.pending is non-zero. If the
     target vCPU is in the UNITIALIZED state, the spurious request will
     result in KVM exiting to userspace, which in turn causes QEMU to
     constantly acquire and release QEMU's global mutex, to the point
     where the BSP is unable to make forward progress.

   - Fix a type (u8 versus u64) goof that results in pmu->fixed_ctr_ctrl
     being incorrectly truncated, and ultimately causes KVM to think a
     fixed counter has already been disabled (KVM thinks the old value
     is '0').

   - Fix a stack leak in KVM_GET_MSRS where a failed MSR read from
     userspace that is ultimately ignored due to ignore_msrs=true
     doesn't zero the output as intended.

  Selftests cleanups and fixes:

   - Remove redundant newlines from error messages.

   - Delete an unused variable in the AMX test (which causes build
     failures when compiling with -Werror).

   - Fail instead of skipping tests if open(), e.g. of /dev/kvm, fails
     with an error code other than ENOENT (a Hyper-V selftest bug
     resulted in an EMFILE, and the test eventually got skipped).

   - Fix TSC related bugs in several Hyper-V selftests.

   - Fix a bug in the dirty ring logging test where a sem_post() could
     be left pending across multiple runs, resulting in incorrect
     synchronization between the main thread and the vCPU worker thread.

   - Relax the dirty log split test's assertions on 4KiB mappings to fix
     false positives due to the number of mappings for memslot 0 (used
     for code and data that is NOT being dirty logged) changing, e.g.

Merge tag 'trace-v6.8-rc4' of git://git./linux/kernel/git/trace/linux-trace

Pull tracing fixes from Steven Rostedt:

 - Fix the #ifndef that didn't have the 'CONFIG_' prefix on
   HAVE_DYNAMIC_FTRACE_WITH_REGS

   The fix to have dynamic trampolines work with x86 broke arm64 as the
   config used in the #ifdef was HAVE_DYNAMIC_FTRACE_WITH_REGS and not
   CONFIG_HAVE_DYNAMIC_FTRACE_WITH_REGS which removed the fix that the
   previous fix was to fix.

 - Fix tracing_on state

   The code to test if "tracing_on" is set incorrectly used
   ring_buffer_record_is_on() which returns false if the ring buffer
   isn't able to be written to.

   But the ring buffer disable has several bits that disable it. One is
   internal disabling which is used for resizing and other modifications
   of the ring buffer. But the "tracing_on" user space visible flag
   should only report if tracing is actually on and not internally
   disabled, as this can cause confusion as writing "1" when it is
   disabled will not enable it.

   Instead use ring_buffer_record_is_set_on() which shows the user space
   visible settings.

 - Fix a false positive kmemleak on saved cmdlines

   Now that the saved_cmdlines structure is allocated via alloc_page()
   and not via kmalloc() it has become invisible to kmemleak. The
   allocation done to one of its pointers was flagged as a dangling
   allocation leak. Make kmemleak aware of this allocation and free.

 - Fix synthetic event dynamic strings

   An update that cleaned up the synthetic event code removed the return
   value of trace_string(), and had it return zero instead of the
   length, causing dynamic strings in the synthetic event to always have
   zero size.
