IIO: New device support, features and cleanup for 6.19
The usual bunch of new device support, but also quite a bit of cleanup
of the core and older drivers which is always good to see.
New device support
------------------
adi,ad4080
- Add support for AD4081, AD4083, AD4084, AD4086 and AD4087 ADCs with
slightly different features to existing supported parts (max CNV clock
count, resolution etc)
adi,adxl380
- Add support for ADXL318 and ADXL319 which have reduced functionality
compared to other supported parts, particularly around event detection.
aosong,adp810
- New driver for this differential pressure and temperature sensor.
aspeed,adc
- Add support for the AST2700 SoC ADCs which differ in small ways from
already supported parts.
bosch,sm330
- New driver for this IMU (accelerometer + gyroscop) with I2C and SPI bus
support.
invensense,icm45600
- New driver for this family of IMUs with sub drivers for accelerometer
and gyroscope elements. I2C, I3C and SPI busses all supported.
* Supports ICM45605, ICM45606, ICM45608, ICM45634, ICM45686, ICM45687,
ICM45688P, ICM45689.
* Support basic features and FIFO.
maxim,max14001
- New driver for the MAX14001 and MAX14002 ADCs.
renesas,rzt2h
- New driver supporting the RZ/T2H and RZ/N2H ADCs found in various SoCs.
renesas,rznl
- New driver supporting the RZ/NL ADC found in various SoCs.
Features
--------
adi,ad5446
- Add a DT binding doc for the 29 variants currently covered by the driver.
- Add adi,ad5542 which is compatiable with the adi,ad5542a which was
already supported.
bosch,bma220
- I2C support including an I2C bus watchdog.
- Power supply control
- Data ready trigger.
- Low pass filter control.
- Debugfs register access.
- Add Petre Rodan as a maintainer of this driver (thanks!)
bosch,bmi270
- Add support for motion events.
fsl,mpl3115
- Add a dataready trigger and related sampling frequency control.
- Add threshold events.
infineon,dps310
- Add a specific device tree binding.
maxim,max30100
- Allow control of LED pulse-width in dt-binding. Optimum value depends
on physical characteristics of the device which contains this sensor.
mediatek,mt2701
- Add dt compatible for the mt8189.
rockchip,saradc
- Add rk3506 compatible which is functionally the same as the already
supported rk3528 (which is therefore the fallback)
st,lsm6dsx
- Make sampling more flexible when both fifo and events are of interest
by decoupling the FIFO fill rate from actual sampling.
Cleanup and minor fixes
-----------------------
core
- Document and add might_sleep() to iio_push_to_buffers_with_ts_unaligned()
as it allocates a buffer, typically just on 1st call.
- Add documentation for iio_push_to_buffers_with_ts() which is being used
to replace iio_push_to_buffers_with_timestamp() in new code as it
validates the buffer size. Make the deprecation of the old function
clear.
- Document that the store_to() callback in struct iio_buffer_access_funcs
may be called from contexts that cannot sleep.
- Document that the cb() provided to a callback buffer may be called
from contexts that cannot sleep.
- Cleanup up industrialio-backend.c comments.
- Call mutex_destroy() in cleanup of buffers.
- Call device_initialize() later to avoid having to call device_put()
before configuration is otherwise complete.
- Use mutex_init_with_key() to replace opencoded version.
- Use dma_buf_unmap_attachment_unlocked() to replace opencoded version.
- Reorder Makefile for pressure sensors.
various
- Uses sysfs_emit() to replace sprintf() in read_label() and other
callbacks that typically are used to write data to sysfs buffers.
- Switch to REGCACHE_MAPLE in various drivers.
adi,docs
- Fix up formatting of cross references and other kernel-doc issues.
adi,ad4080
- Fix wrong masking of product IDs.
adi,ad5446
- Use DMA safe buffers as needed for SPI.
- Drop a duplicate device chip specific data structure where two parts
are functionally identical.
- Fail probe if reference is not available.
- Split up the massive array of chip type specific structures into
separate structures as this tends to be easier to read and maintain.
- Add explicit of_device_id entries for all supported parts.
- Split I2C and SPI parts away from core to avoid ifdef complexity.
- Switch to devm_mutex_init().
- Make use of guard() to simplify code.
- Applying IWYU principles and reorder headers.
- Various other minor cleanup.
adi,ad7124
- Add debugfs to support single cycle mode, typically only used for cases
such as validate performance of the ADC.
- Various other minor cleanup including removing some layers of indirection
that weren't necessary.
- Add extended attributes to the temperature channel which follows the same
signal path as other channels.
- Replace the setup register allocation strategy with a simpler more
predictable one (a fix for OOB from this code follows later in this pull
request).
adi,adxl345
- Ensure dt-binding allows for both interrupt wired at the same time.
arm,scmi
- Replace const_ilog2() with the resulting value which ends up simpler
to read.
bosch,bma220
- Add correct SPI mode specification to the device tree binding.
- Fix up interrupt type in dt binding example to match that the driver
expects.
- Relax hard constraint on matching chip ID with a message only so as to
enable fallback DT compatibles to work.
- Use local struct device *dev to replaces lots of indirect look ups.
- Improve includes on approximate IWYU basis.
- Explicit of_match_table.
- Reset some registers during probe.
- Move to regmap.
- Ensure a timestamp is available when filling the buffer by using a
locally acquired one rather than relying on trigger top half running.
- Add a utility function to search value pair tables for a match.
- Various other minor improvements.
- Move code to avoid a false dependency of the core code on the I2C module.
bosch,bma400
- Improve register and field naming + organization. Use with FIELD_GET()
and FIELD_PREP() to allow dropping of shift defines.
- Use macros to define event related fields.
- Switch to an address lookup based on an index variable to replace lots of
very similar register macros.
- Rename activity_event_en() to generic_event_en() to better reflect what
it does.
- Improve comments around interrupt register handling.
fsl,mpl3115
- Factor out code for triggered buffer data collection.
- Use more consistent register field naming style.
- Use get_unaligned_be24() to get the pressure.
invensense,mpu6050
- Drop false requirement in DT binding for the interrupt. The driver will
be able to do less if one is not provided, but some features are still
available.
invensense,icm45600_i3c
- Fix missing return on failure to match part.
linear,ltc2688
- Use devm_mutex_init() so mutex_destroy() is called in tear down path.
- Use guard() to simplify lock handling in error return paths.
qcom,vadc
- Fix up some kernel-doc related warnings.
rohm,bd79112 and bd79124
- Use regmap_reg_range() helper to set the ranges.
st,lsm6dsx
- Fix units of ODR in structure documentation.
ti,am335x
- Add range checks to avoid a compiler warning.
ti,pac1934
- Switch to system_percpu_wq.
Various other minor typo fixes etc.
