Subject: [PATCH v4 00/13] Support more parts in LTC2983

Add support for the following parts:
 * LTC2984
 * LTC2986
 * LTM2985

The LTC2984 is a variant of the LTC2983 with EEPROM.
The LTC2986 is a variant of the LTC2983 with only 10 channels,
EEPROM and support for active analog temperature sensors.
The LTM2985 is software-compatible with the LTC2986.

Also, make bulk write buffer DMA-safe.
Besides that, refine the binding.

V1 -> V2:
 * add Fixes tag
 * add patch that fixes the regmap_bulk_write() call with stack allocated
   buffer
 * add patch that refines the binding in preperation for adding new
   parts support to it
 * do not use stack allocated buffer for writing the EEPROM key

V2 -> V3:
 * drop minItems if equal to maxItems
 * drop adi,single-ended conditions because of recent dtschema
   restrictions (even though they're valid in jsonschema and the last
   dtschema tag)
 * drop "allocate iio channels once" patch since it's been picked as a fix

V3 -> V4:
  * add pipe for 'adi,mux-delay-config-us' description
  * add pipe for 'adi,rtd-curve' description
  * keep newlines after descriptions
  * move 'adi,current-rotate' to conditional
  * put 'adi,custom-steinhart' in the original place
  * keep 'minItems' for 'adi,custom-steinhart'
  * override 'enum' to forbid auto-range in 'adi,excitation-current-nanoamp'
    when using custom thermistors
  * split refine patch into multiple patches
    - use generic node name in example
    - describe broken mux delay property
    - refine descriptions
    - change default excitation for custom thermistors
    - require 4 wire rtd for current rotate
    - require custom sensor tables
    - describe matrix items
    - remove qutations from phandle ref
    - use hex for sensor address
    - add default values
