Second set of new device support, features and cleanup for IIO in the 4.18 cycle
Usual mixture of new devices support and other stuff. A couple of
staging graduations in here and some old driver drops.
New device support
* ad5686
- Add support for AD5691R, AD5692R, AD5693 and AD5693R i2c DACs
- Add support for AD5681R, AD5682R, AD5683 and AD5683R SPI DACs
* lmp91000
- Add ID for LMP91002
* stm32-dfsdm
- Add support for the stm32mp1 devices.
Drivers dropped
* ADE7753
- No longer easily available, no users came forward and needs a lot
of work to move out of staging.
* ADE7754
* ADE7758
* ADE7759
Staging graduations
- ad2s1200 - good cleanup from David Veenstra.
- tsl2772 (was tsl2x7x) - Brian's quest is at an end and
staging/iio/light is no more!
Features
* tools
- loop forever on a negative number of loops being specified.
* ltc 2632
- add of_match_table
- support an external reference regulator.
* mag3110
- Support continuous mode when running fast as it increases the
posssible sampling rate.
* ti-ads8688
- Add trigger and buffer support to this ADC.
Cleanups / minor tweaks.
* tools
- tidy up types in iio_generic_buffer.
* ad2s1200
- Whitespace cleanup.
- Drop pointless initializations.
- Improve kernel docs.
- Reorder to setup the SPI prior to device registration (race fix).
- Change to modern gpiod framework.
- Drop platform data and move to DT bindings. There are no in
kernel users of the platform data. Any out of tree boards will
need changes.
- Add an explicit compatible table.
- Provide _scale for angular velocity and angle channels.
- Add David Veenstra to copyright notice as this cleanup was non
trivial.
* ade8366
- Avoid a race by ensuring channel init is before registration
with the subsystem.
* afe
- binding spelling fix.
* imx7d-adc
- typo fix in Freescale
* inv_mpu6050
- tidy up an ugly loop to take advantage of known entry condition.
- add a comment explaining why the sensible sampling frequencies
are more limited than might be immediately apparent (aliasing).
* mma8452
- reduce the sleep time on data not ready when running at high
frequency.
* stm32-dfsdm
- add missing header.
* tsl2583
- fix integration_time_availabe which was in microsecs rather the
millisecs.
* tsl2x7x/tsl2772
- Whitespace cleanup.
- Change to direct returns where sensible.
- Turn the chip off in the registration error path.
- Use macro to reduce repition when setting up the device_info
structures.
- Change the _available attributes over to read_avail callback,
and the range definitions that supports.
- Fix some wrong period values.
- Add some range checkign for _write_raw.
- Rename the driver to tsl2772 to avoid wild card clash problems
in future.
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.
