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

From: Cosmin Tanislav
Date: Tue Oct 25 2022 - 04:19:10 EST


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

Cosmin Tanislav (4):
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
