      iio: imu: lsm6dsx: Support SMO8B30 ACPI ID for LSM6DS3TR-C · bd66b6ac
      Jonathan Cameron authored
      ID seen in the wild and it is a valid ST micro ID.
      An offset of 1 for the device ID enum is needed when adding support for
      retrieving the ID from device_get_match_data() to allow detection of
      NULL pointer and fallback to i2c_device_id table.

      Jonathan writes:
      
      1st set of IIO new device support, features and cleanups for the 6.4 cycle.
      
      New device support
      * bosch,bmp280
        - Add support for BMP580 - includes significant refactoring and general
          driver cleanup + support for non-volatile memory for trimming and config
          parameters.
      * rohm BU27034
        - New driver for this 3 channel ambient light sensor.
        - New support library for devices where both integration time and
          amplifier gain are configurable.  In these cases a scale change
          may require changing bother underlying values. This library module
          provides code to help with this.
      * st,accel
        - Add support for IIS328DQ (ID only as compatible wtih LIS331DL)
      * st,lsm6dsx
        - Add support for ASM330LHB automotive MEMS sensor.
      * ti,ads1100, ads1000
        - New driver for these 16 bit ADCs.
      * ti,tmp117
        - Add support for older tmp116 device. Includes some general driver cleanup.
      
      Staging driver drops
      * adi,ade7854
        - Driver was a very long way from compliant with IIO infrastructure and ABI.
          If anyone wants a non staging version of this driver they are better off
          starting from scratch. Hence drop it and the associated meter.h header.
      
      Features
      * adi,ad7441r
        - Add DT binding to set sink current for digital input.
      * semtech,sx9324,9360
        - Support older register mapping from firmware designed for windows.
      
      Core improvements.
      * Move iio_trigger_poll() docs to next to the implementation and add a note
        on expected caller context.
      * Rename iio_trigger_poll_chained() to iio_trigger_poll_nested() so
        as to use more standard / common terminology.
      * Improve main ABI docs references to offset and scale for raw values by
        making them consistent and clear.
      
      Cleanups and minor fixes:
      * adi,ad5592r
        - Add GPIO names - useful for debug.
      * adi,ad7441r
        - Fix current input, loop powered mode configuration setup.
      * adi,adis16475
        - Fix wrong commented value for minimum advised lower rate.
      * adi,admv1013
        - Use devm_clk_get_enabled() to reduce boilerplate.
      * adi,ads1210
        - Fix wrong bits for writing config register (late fix and has
          been broken a long time so not rushed upstream)
      * amlogic,meson-saradc
        - Improve cleanup in error handling if BL30 handshake fails.
      * apex-embedded,stx104
        - Migrate to regmap and use regmap_read_poll_timeout() to neatly handle
          retries.
        - Add local mutex to close various races.
        - Use define U16_MAX rather than value for limit.
        - Improve code readability with minor reorganization.
      * atmel,ad91-sama5d2
        - Drop trivial dead code.
      * kionix,kx022a
        - Drop unused structure element.
      * linear,ltc2983
        - Reorganize bindings doc to enable unevaluatedProperties to be set
          in one place for all child nodes.
        - Make binding for adi,custom-thermocouple accept signed values.
      * maxim,max44000
        - Add OF Device matching (of_match_table was not correctly set).
      * maxim,max5522
        - Missing static
      * measurement-computing,cio-dac
        - Fix wrong part name in comments.
        - Migrate to regmap.
        - Improve includes by replacing bitops.h with more direct bits.h
      * qcom,pm8xxx-xoadc
        - Remove a check that can never fail.
      * renesas,rcar-gyroadc
        - DT binding documentation improvements.
        - Tidy up an unused warning with __maybe_unused.
      * semtech,sx_common
        - Drop docs for a structure element that doesn't exist.
      * semtech,sx9500
        - Drop ACPI_PTR() and of_match_ptr() protections that just complicate
          the code / block some firmware registration types that would otherwise
          work.
      * sensiron,sps30
        - Comment formatting tidy up.
      * st,sensors
        - Drop duplicate text in DT binding.
      * st,stm32-adc
        - Add some missing static markings.
      * ti,ads1100
        - Use correct return code in dev_err_probe() call.
      * x-powers,axp20x_adc - precursor series to simplify addition of AXP192.
        - General code cleanup / minor refactoring for better readabilty of code.
        - Switch from boolean value to mask for adc_en2 field to avoid hard coding
          a mask that will be different in AXP192

      Pull compute express link (cxl) fixes from Dan Williams:
       "Several fixes for driver startup regressions that landed during the
        merge window as well as some older bugs.
      
        The regressions were due to a lack of testing with what the CXL
        specification calls Restricted CXL Host (RCH) topologies compared to
        the testing with Virtual Host (VH) CXL topologies. A VH topology is
        typical PCIe while RCH topologies map CXL endpoints as Root Complex
        Integrated endpoints. The impact is some driver crashes on startup.
      
        This merge window also added compatibility for range registers (the
        mechanism that CXL 1.1 defined for mapping memory) to treat them like
        HDM decoders (the mechanism that CXL 2.0 defined for mapping
        Host-managed Device Memory). That work collided with the new region
        enumeration code that was tested with CXL 2.0 setups, and fails with
        crashes at startup.
      
        Lastly, the DOE (Data Object Exchange) implementation for retrieving
        an ACPI-like data table from CXL devices is being reworked for v6.4.
        Several fixes fell out of that work that are suitable for v6.3.
      
        All of this has been in linux-next for a while, and all reported
        issues [1] have been addressed.
      
        Summary:
      
         - Fix several issues with region enumeration in RCH topologies that
           can trigger crashes on driver startup or shutdown.
      
         - Fix CXL DVSEC range register compatibility versus region
           enumeration that leads to startup crashes
      
         - Fix CDAT endiannes handling
      
         - Fix multiple buffer handling boundary conditions
      
         - Fix Data Object Exchange (DOE) workqueue usage vs
           CONFIG_DEBUG_OBJECTS warn splats"
