Merge tag 'iio-for-6.14a' of ssh://gitolite.kernel.org/pub/scm/linux/kernel/git/jic23/iio into char-misc-next

Pull IIO updaate from Jonathan:

IIO: 1st set of new device support, features and cleanup for 6.14

Fairly quiet cycle. Usual mix of new drivers, device support in
existing drivers, features and more general rework and cleanup.
There are a few late breaking or long standing but complex fixes
in here as well.

There is one expected merge conflict due to an upstream fix touching
neighboring code in ti-ads1119. The trivial resolution is the right one with
the result ending up as:

	struct {
		s16 sample;
		aligned_s64 timestamp;
	} scan;

New device support
==================

adi,ad4000
- Add support for many Pulsar ADC devices: AD7685, AD7686, AD7687, AD7688,
  AD7690, AD7691, AD7693, AD7942, AD7946, AD7980, AD7982, AD7983, AD7984,
  AD7988-1 and AD7988-5 ADCs. Generally similar to the AD4000 series
  but with lower sampling rates and no configuration registers.
  Includes addition of timestamp channels.
adi,adis16480
- Add support for ADIS16486, ADIS16487 and ADIS16489 IMUs. Required a few tweaks
  to existing driver and addition of tables.
kionix,kx022a
- Add support for KX134ACR-LBZ accelerometer that is similar to the
  KX132ACR-LBZ but with a wider (+-64G) sensor range.
- Add support for KX134-1211 accelerometer that is similar to the
  KX132-1211 but with a wider (+-16G) sensor range.
nxp,fxls8962af
- Add support for fxls8974cf and fxls8967af accelerometers, Both are
  compatible with fxls8962af but with different device IDs which are used in
  presence checks.
renesas,rzg2l
- Add support for Renesas RZ/GS3 SoC ADCs (various driver refactors
  precede this to allow for chip differences).
rohm,bd79704
- New driver for this 6 channel DAC.
st,mpu6050
- Support he IAM20380 which is effectively a cut down IAM20608 IMU with only
  a gyroscope (no accelerometer).
st,stm-timmer-trigger
- Add support for ADC trigger use case for the STM32MP25 SOC. Do not support
  the counter functionality in this driver as that is handled by the
  counter subsystem.
ti,opt4060
- New driver for this RGBW color sensor.

Driver drop
===========

rohm,bu20008
- Drop as decision was made to not mass produce this light sensor after
  Matti had done all the work to get a driver upstream.

Features
========

adi,ad_sigma_delta library + ad7124
- Allow for GPIO to check interrupt status, enabling this device on
  more platforms that don't obey prior (non general) assumptions on
  how the interrupt chips work.
- Allow variation in reset sequence length allowing chip specific
  optimizations rather than always using worst case.
adi,ad7124
- Add temperature channel support.
adi,ad7173
- Add support calibration modes for this family of ADCs.
adi,adxl345
- Binding update to allow specification of which interrupt line is
  connected (or none).
- Support interrupts and FIFO based data capture.
bosch,bme680
- Add regulators support. Note this required a new binding doc rather than
  use of trivial-devices
- Runtime PM support.
microchip,pac1921
- Add ACPI support including _DSM for shunt value and label.
renesas,rzg2l
- Enable runtime autosuspend.
- Add suspend and resume support.
tyhx,hx9023s
- Add loading of a firmware file used to set defaults for some
  configuration registers.
vishay,veml6030
- Support triggered buffers allowing efficient data capture at
  higher speeds.
- Add regmap cache to reduce access to device.

Cleanup and minor fixes
=======================

cross-tree
- Another batch of conversions to devm_regulator_get_enable_read_voltage()
  helper and related conversions to full devm that this enables.
- Various patches using guard() to allow early returns and simpler
  code flow.
- Various conversions from s64 timestamp __aligned(8) to aligned_s64 type.
  Includes a few cleanups where this unsigned and it should have been
  signed.
- Fix up some missing types for drive-open-drain in dt-binding docs.
core
- Add missing documentation for iio_dmaengine_buffer_setup_ext()
- Add check that all buffers passed to iio_read_channel_ext_info()
  and iio_read_channel_label() are page sized and page aligned.
  Done this way because the callbacks are almost always only used
  to fill sysfs attributes. The check covers the tiny percentage
  of cases where use is made of this data in a consumer driver.
- Mark scan_timestamp memory of struct iio_dev private ensuring no
  drivers change the value which belongs to the IIO core.
documentation
- Various missing ABI docs added.
- ABI docs made to use Y consistently as the wildcard for channel
  number.
- Combine duplicate in_currentY_raw entries in ABI docs.
iio-mux
- Fix alignment of buffers passed to iio_channel_read_ext_info().
adi,ad_sigma_delta library
- Respect keep_cs_asserted flag in read path.
- Close a race condition around irq enabling and disabling.
- Use explicit unsigned int in place of unsigned.
adi,ad6695
- Move dt-binding header under adc sub-directory and fix include path in dt
  example.
adi,ad7124
- Check number of channels in DT doesn't exceed what the driver can handle.
- Check input specified in DT are possible.
- Improved error reporting during probe.
adi,ad7173
- Drop unused structure element.
adi,ad7293
- Ensure power is turned on before resetting.
adi,adxl345
- Some documentation simplification and parameter renames.
- Add a function than unifies handling of power up and power down.
- Add defines to have a complete set of registers defined.
- Add missing \n to end of error messages.
amlogic,meson_saradc
- Simplify handling of the REG11 register access.
awinic,aw96104
- Constify iio_info structure.
bosch,bmp085
- Add to dt-binding to indicate devices support SPI.
bosch,bmp280
- Use sizeof() to replace a somewhat magic 2.
- Rename sleep related variables so the unit is included and use
  fsleep() to replace usleep_range() calls.
bosch,bno055
- Constify struct bin_attribute
capella,cm3232
- Reset device before checking hardware ID inline with suggested flow
  from datasheet.
diolan,dln2
- Simplify zeroing of structure used to gather up data by just
  clearing the whole thing before writing rather than trying to
  clear out he padding after write.
freescale,vf610
- Use devm_ and dev_error_probe() to simplify code and allow dropping
  of explicit remove() callback.
invensense,timestamp library
- Use a cast to remove possibility of integer overflow.
kionix,kx022a
- Increase reset delay a little.
maxim,max1363
- Use a buffer of sufficient size in iio_priv() rather than allocating
  variable sized buffer at use time.
microchip,mcp4725
- Replace of_property_read_bool() with of_property_present() for
  detecting presence of regulator which is obviously not a bool.
nxp,fxls8962af
- Add wakeup-source property to the dt binding to allow these sensors
  to wake the system up from suspend.
- Enable finer grained build when not all bus types need to be supported.
renesas,rzg2l
- Use dev_err_probe(), improving handling of probe errors and simplifying
  code.
- Convert to devm_ based cleanup.
- Remove unnecessary runtime PM complexity as clocks are managed through
  PM domains.
- Switch pm_ptr() removing need for __maybe_unused markings.
- use read_poll_timeout() to replace open coded equivalent.
samsung, ssp_sensors
- Simplify code by always providing timestamp whether or not it
  is enabled.
st,lsm6dsx
- Avoid need to include linux/i3c/master by using i3cdev_to_dev() to
  get to the contained struct device.
st,stm32-timer-trigger
- Check for clk_enable() fails.
vishay,veml6030
- Use new gts-helper functions and fix the _scale attribute to take into
  account changes in gain and integration time.

Various other typo fixes in variable names + documentation and help text.
A few whitespace cleanup patches.
