  iio: accel: bma180: BMA254 support (2019-12-30 16:29:09 +0000)

----------------------------------------------------------------
First set of new device support, features and cleanups for IIO in the 5.6 cycle

New device support

* ad7091r5 ADC
  - New driver with follow up patch adding scale and vref support.
  - DT bindings
* ad7923
  - Support for ad7908, ad7918 and ad7928 added to driver.
* bma180
  - Support the BMA254 accelerometer. Required fairly substantial rework
    to allow for small differences between this an existing parts.
* bma400 accelerometer
  - New driver with follow up patch for regulator support.
  - DT bindings.
* asc dlhl60d
  - New driver support this range of pressure and temperature sensors.
  - DT bindings.
* ltc2496 ADC
  - New driver to support this ADC.
  - Split the existing LTC2497 driver generic component out and reuse.
  - DT bindings.
* parallax ping
  - New driver supporting ultrasonic and laser tof distance sensors.
  - Bindings for these sensors.

New features

* core
  - New char type for read_raw returns, used for thermocouple types.
  - Rename read_first_n callback to read.   The reasons behind the original
    naming are lost to the mists of time.
* ad799x
  - Allow pm_ops to disable device completely allowing regulator power down.
* bma180
  - Enable basic regulator support.
* dmaengine buffer
  - Report platform data alignment requirements via new ABI.
* max31856
  - Add option to set mains filter rejection frequency and document
    new in_temp_filter_notch_center_frequency ABI.
  - Add support for configuring HW averaging (oversampling ratio)
  - Add runtime configuration of thermocouple type and document new ABI.
* maxim-thermocouple
  - Add read only access to thermocouple type using new ABI, includes
    adding more specific compatibles to reflect which variant of the
    chip is being used.
* mpu6050
  - Provide option to support the PMU9150 in package magnetometer directly
    rather than via auxiliary bus.
* stm32_adc
  - Add overrun interrupt checks to detect if this happens.
* st_lsm6dsx
  - Enable the sensor-hub support for lsm6dsm. Includes various reworks to
    allow this.

Cleanups and minor fixes

* Subsystem wide
  - Tidy up indentation in Kconfig and fix alphabetical order of AD7091R5.
  - Drop linux/gpio.h and linux/of_gpio.h from drivers that don't use them.
* ad7266
  - Convert to GPIO descriptors.
* ad7303
  - Avoid a dance with checking if the regulator is supplied by just
    using the optional request interface.
* ad7887
  - Simplify channel specification assignment to enable adding more devices.
* ad7923
  - Drop some unused and largely pointless defines of BOB_N==N variety.
  - Tidy up checkpatch warnings.
  - Add missing of_device_id table.
* adf4350
  - Convert to GPIO descriptors.
* ak8975
  - Convert to GPIO descriptors.
* ADIS library and drivers
  - Expand scope of txrx_lock to cover all state and rename as state_lock
  - Add unlocked read / write to allow grouping of consecutive calls under
    single lock / unlock.
  - Add unlocked check_status, reset to allow grouping under single
    lock / unlock.
  - Remove remaining uses of core mlock for local state protection.
    mlock should never be used directly as it protects tightly defined
    core IIO device management state.
* adis16240
  - Enforce only supported SPI mode on driver load + add DT binding doc.
* atlas-ph-sensor
  - Rename to atlas-sensor given it now covers things beyond ph sensors.
* bma180
  - Use local dev variable to tidy up code.
  - Use c99 style explicity .member assignment to make driver more readable.
* bmp280
  - Drop ACPI support. No evidence this was used and appropriate ID is not
    registered.
  - Allow ACPI to bind device via PRP0001
* dmaengine buffer
  - Use dma_request_chan instead of dma_request_slave_channel_reason as that
    ABI is going away.
  - Add module info to avoid tainting the kernel.
* hts221
  - Avoid magic number defines when only used to fill structure elements
    that are self describing.
* lm3533
  - Drop a stray semicolon.
* max9611
  - Cleanup enum handling to be more resilient to future changes.
* mpu6050
  - Delete MPU9150 from supported SPI devices as doesn't provide SPI.
  - Select I2C_MUX again after kbuild issue fixed elsewhere.
* stm32-timer
  - Drop an unnecessary register update.
* ssp_sensors
  - Convert to GPIO descriptors.
* st_sensors
  - drop !CONFIG_ACPI defines as ACPI_PTR() will stop them being used
    anyway.
  - Make default platform data structures __maybe_unsued.
  - Fill in some missing kernel-doc function parameters.
* st_lsm6dsx
  - white space fixes.
  - Mark some constants that aren't always used as __maybe_unused.
  - Drop of ID table guards as they just pervent use under ACPI.
  - Switch to device properties to allow ACPI usage.
* st_uvis25
  - Drop acpi.h include as no ACPI APIs used.
* ti-ads1015
  - Drop legacy platform data as no one seems to be using it.
  - Use the device property API instead of OF specific.
* ti-ads7950
  - typo fix in error message.
