Jonathan writes:

First set of new device support, features and cleanup for IIO in 5.10 cycle, take 2

A few changes to how I write this cover letter.
* Started to use manufacturer prefixes to group changes better.
* Stop list minor formatting etc changes.
* Whilst I appreciate those changes, we don't need to call them out here.

New device support:
* adi,adxrs290
  - New driver for this gyroscope with dt bindings. One fix follows.
* ams,as73211
  - New driver for this colour sensor with dt bindings. Also includes
    docs for XYZ modifiers as used for the CIE colour space. Sysfs docs.
* atlas,atlas-ezo-sensor
  - Support O_2 sensor, includes new modifier for concentration.
  - Support humidity sensor.
* ti,hdc2010
  - New driver support hdc2010 and hdc2080 humidity sensors. Includes dt
    bindings.

Cleanup, minor fixes and features
* core
  - Make the trigger related stub functions static inline, avoiding some build
   warnings.
  - buffer-dmaengine. Allow adjusting bytes_used with residue info.
* dev_error_probe to replace open coded equivalent in many drivers.
* docs and comment fixes
  - Fix some typos, doubled words, capitalisation and punctuation.
* dt binding conversions to yaml
  - lltc,ltc2497
  - lltc,ltc2632
  - maxim,max11100
  - maxim,max1118
  - maxim,max9611

  - microchip,mcp342x (add to trivial devices)
  - ti,adc0832
  - ti,adc108s102
  - ti,adc128s052
  - ti,adc161s626
  - ti,ads8344
  - ti,tlc4541 (includes adding an accidentally dropped original binding doc)
* adi,adi-axi-adc
  - Use kobj_to_dev instead of open coding.
* adi,ad5686
  - Constify iio_chan_spec
* adi,ad8366
  - Add HMC1119 to kconfig help text as the driver supports it.
* adi,ad9523
  - Use devm for reset of probe and drop remove.
* adi,adxl372
  - Tidy up alignment
  - Add OF table
  - Add peak mode support with some docs.
* bosch,bma220 (general tidy up)
  - Fix some return codes.
  - Use read_avail callback rather than open coding attrs.
  - Use dev_get_drvdata rather than dance via to_spi_device()
  - Mark PM functions as __maybe_unused rather than #ifdef fun.
  - Drop ACPI_PTR protections and ifdefs.
  - Tidy up header ordering.
  - BIT and GENMASK
* broadcom,bcm_iproc
  - Drop of_match_ptr protection and switch to mod_devicetable.h
    Part of general move to get this anti-pattern out of IIO.
* melexis,mlx90614
  - Simplify some calculations.
  - Add some kernel_doc
  - Use regmap poll loop rather than open coding.
  - Add extended calibration option.
* sensortec,sx9310, wide ranging set of fixes and cleanups.
  - Document dt-binding.
  - Rename some macros to align better with spec sheet
  - Fix some issues with irq handling.
  - Drop of_match_ptr and ACPI_PTR macros to avoid unused warnings etc.
  - Switch to probe_new
  - Fix memory alignment for iio_push_to_buffers_with_timestamp()
  - Use long for bitmaps to allow use of for_each_bit_set()
  - Use regmap_read_poll instead of opencoding.
  - Simplify error paths
  - Enabled regulators at probe.
  - Use trigger flags from firmware rather than forcing them in the driver.
* ti,adc081c
  - Drop ACPI IDs that are not likely to be official ones and we don't believe
    anyone is using.
* ti,adc108s102
  - Drop CONFIG_OF and of_match_ptr protections.
* ti,adc128s052
  - Drop of_match_ptr protection and include mod_devicetable.h
* ti,dac5571
  - Support powerdown for mutlichannel usecases.
* xpowers,axp20x
  - Convert from OF to generic fw / device properties. Unlikely anyone will
    use this with anything other than devicetree, but this is part of a
    general move across IIO.

      staging: tegra-vde: fix common struct sg_table related issues · 76f50ad9
      Marek Szyprowski authored 
      The Documentation/DMA-API-HOWTO.txt states that the dma_map_sg() function
returns the number of the created entries in the DMA address space.
However the subsequent calls to the dma_sync_sg_for_{device,cpu}() and
dma_unmap_sg must be called with the original number of the entries
passed to the dma_map_sg().

struct sg_table is a common structure used for describing a non-contiguous
memory buffer, used commonly in the DRM and graphics subsystems. It
consists of a scatterlist with memory pages and DMA addresses (sgl entry),
as well as the number of scatterlist entries: CPU pages (orig_nents entry)
and DMA mapped pages (nents entry).

It turned out that it was a common mistake to misuse nents and orig_nents
entries, calling DMA-mapping functions with a wrong number of entries or
ignoring the number of mapped entries returned by the dma_map_sg()
function.

To avoid such issues, lets use a common dma-mapping wrappers operating
directly on the struct sg_table objects and use scatterlist page
iterators where possible. This, almost always, hides references to the
nents and orig_nents entries, making the code robust, easier to follow
and copy/paste safe.
