[v3,0/4] Support more parts in LTC2983

Message

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.

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

  iio: temperature: ltc2983: make bulk write buffer DMA-safe
  dt-bindings: iio: temperature: ltc2983: refine
  dt-bindings: iio: temperature: ltc2983: support more parts
  iio: temperature: ltc2983: support more parts
