Second set of IIO new device support, features and cleanups.
There are also a couple of fixes that can wait for the coming merge
window.
Core new features
* Support for phase channels (used in time of flight sensors amongst
other things)
* Support for deep UV light channel modifier.
New Device Support
* AD4758 DAC
- New driver and dt bindings.
* adxl345
- Support the adxl375 +-200g part which is register compatible.
* isl29501 Time of flight sensor.
- New driver
* meson-saradc
- Support the Meson8m2 Socs - right now this is just an ID, but there will
be additional difference in future.
* mpu6050
- New ID for 6515 variant.
* si1133 UV sensor.
- New driver
* Spreadtrum SC27xx PMIC ADC
- New driver and dt bindings.
Features
* adxl345
- Add calibration offset readback and writing.
- Add sampling frequency control.
Fixes and Cleanups
* ad5933
- Use a macro for the channel definition to reduce duplication.
* ad9523
- Replace use of core mlock with a local lock. Part of ongoing efforts
to avoid confusing the purpose of mlock which is only about iio core
state changes.
- Fix displayed phase which was out by a factor of 10.
* adxl345
- Add a link to the datasheet.
- Rework the use of the address field in the chan_spec structures to
allow addition of more per channel information.
* adis imu
- Mark switch fall throughs.
* at91-sama5d2
- Fix some casting on big endian systems.
* bmp280
- Drop some DT elements that aren't used and should mostly be done from
userspace rather than in DT.
* hx711
- add clock-frequency dt binding and resulting delay to deal with capacitance
issue on some boards.
- fix a spurious unit-address in the example.
* ina2xx
- Avoid a possible kthread_stop with a stale task_struct.
* ltc2632
- Remove some unused local variables (assigned but value never used).
* max1363
- Use device_get_match_data to remove some boilerplate.
* mma8452
- Mark switch fall throughs.
* sca3000
- Fix a missing return in a switch statement (a bad fallthrough
previously!)
* sigma-delta-modulator
- Drop incorrect unit address from the DT example.
* st_accel
- Use device_get_match_data to drop some boiler plate.
- Move to probe_new for i2c driver as second parameter not used.
* st_sensors library
- Use a strlcpy (safe in this case).
* st_lsm6dsx
- Add some error logging.
* ti-ads7950
- SPDX
- Allow simultaneous buffered and polled reads. Needed on a Lego Mindstorms
EV3 where some channels are used for power supply monitoring at a very low
rate.
* ti-dac5571
- Remove an unused variable.
* xadc
- Drop some dead code.
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
