Greg Kroah-Hartman 43fbd50649 1st set of IIO new device support, features and cleanup for 6.6
New device support
 * adi,ad8366
   - Add support for the HMC792 digital attenuator (mostly chip specific data)
 * alwinner,sun20i-gpadc
   - New driver for the integrated ADC on a number of allwinner SoCs
     including dt-binding documentation.
 * microchip,mcp4728
   - New driver for this quad channel DAC. Includes dt-bindings.
 * miramems, da280
   - Add ID for DA217 accelerometer which is compatible with the da280.
 * murata,irs-d200
   - New driver for this passive infrared sensor typically used for human
     detection. Includes bindings and a few pieces of new ABI to
     cover a case of needing to count a number of repeats of an event
     before reporting it.
 * rohm,bu27008
   - Add initial support for the BU27010 RGB + flickering sensor to this
     driver. Substantial refactoring was needed to enable this.
 
 Features
 * adi,admv8818
   - Add mode that bypasses the input and output filters.
 * amlogic,meson
   - Support control of the MUX on channel 7, exposed as multiple channels.
   - Support channel labels.
 * sensirion,scd4x
   - Add pressure compensation. Controlled via an 'output' pressure channel.
 * ti,lmp92040
   - Add IIO buffered supported (read via chrdev).
 * vishay,vcnl4000
   - Add proximity interrupt support for vcnl4200.
   - Add proximity integration time control for vcnl4200.
   - Add illuminance integration time control for vcnl4040 and vcnl4200.
   - Add calibration bias, proximity and illuminance event period, and
     oversampling ratio control for vcnl4040 and vncl4200.
 
 Cleanup and minor fixes
 * core
   - Tidy up handling of set_trigger_state() callback return values
     to consistently assume no positive return values.
   - Use min() rather than min_t() in a case where types were clearly
     the same.
   - Drop some else statements that follow continue with a loop or
     a returns.
   - White space and comment format cleanup.
   - Use sysfs_match_string() helper to improve readability.
   - Use krealloc_array() to make it explicit a krealloc is for an array
     of structures, not just one.
 * tools
   - Tidy up potential overflow in array index.
 * tree wide
   - Fix up includes for DT related headers.
   - Drop some error prints in places where as similar error message
     is printed by the function being called.
   - Tidy up handling of return value from platform_get_irq() to no longer
     take into account 0 as a value that might be returned. Similar for
     fwnode_irq_get().
 * adi,ad7192
   - Add missing error check and improved debug logging.
   - Use sysfs_emit_at() rather than open coded variant.
 * adi,adis16475
   - Drop unused scan element enum entries.
   - Specify that a few more devices support burst32 mode.
 * adi,admv1013
   - Enable all required regulators and document as required in the
     dt-binding.
 * adi,admv1014
   - Make all regulators required in the dt-binding as the device needs
     them all enabled.
 * adi,adxl313
   - Fix wrong enum values being used in the i2c_device_id table.
   - Use i2c_get_match_data() to reduce open coded handling of the
     various id tables.
 * allwinner,gpadc
   - Make the kconfig text more specific to make space for separate drivers
     for other Allwinner devices.
 * amlogic,meson
   - Drop unused timestamp channels as no buffer support.
   - Various minor reorganizations to enable addition of support channel 7
     MUX.
   - Initialize some default values to account for potential previous user
     since reboot.
 * qcom,spmi-adc5
   - Add ADC5_GPIO2_100K_PU support to driver to line up with bindings.
 * qcom,spmi-adc7
   - Use predefined channel ID definitions rather than values.
 * invensense, common
   - Factor out the timestamp handling to a module used by both mpu6050 and
     icm42600.
 * invensense,mpu6050
   - Read as many FIFO elements as possible in one bus access.
 * men,s188
   - Drop redundant initialization of driver owner field.
 * microchip,mcp4018 and mcp4531
   - Use i2c_get_match_data() instead of open coding. Includes making the
     data format the same for the i2c_device_id and firmware match
     tables.
 * semtech,sx9310
   - dt-bindings: Add reference to IIO schema to provide the label property.
 * semtech,sx9324
   - dt-bindings: Add reference to IIO schema to provide the label property.
 * st,stm32-adc
   - Use devm_platform_get_and_ioremap_resource() instead of open coded
     version.
 * st,stm-lptimer-trigger
   - Drop setting platform drvdata as it wasn't then used.
 * ti,ads1015
   - Fix wrong dt binding description of ti,datarate for some devices.
 * vishay,vcnl4200
   - Move to switch statements for channel type checking to make later
     additions simpler.

README

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.

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.
