Subject: [PATCH v2 0/2] iio: adc: ad7944: new driver
Date: Fri, 16 Feb 2024 13:46:17 -0600

This is a new driver for the Analog Devices AD7944/AD7985/AD7986 family
of ADCs. These are fairly simple chips (e.g. no configuration registers).
The initial driver is only supporting the 'multi' (4-wire) SPI mode. We
plan to follow up with support for the 'single' (3-wire) SPI mode.

This work is done on behalf of Analog Devices, Inc., hence the
MAINTAINERS are @analog.com folks.

Changes in v2:
- Added limit to spi-max-frequency for chain mode in DT bindings
- Added spi-cpol property to DT bindings
- Renamed '3-wire' mode to 'single' mode (to avoid confusion with spi-3wire)
- Renamed '4-wire' mode to 'multi' mode
- Dropped adi,reference property - now using only ref-supply and 
  refin-supply to determine the reference voltage source
- Fixed spelling of TURBO
- Renamed t_cnv to t_conv to match datasheet name and fixed comment
- Fixed wrong timestamp pushed to buffer
- Fixed scaling for chips with signed data
- Make use of sysfs_match_string() function
- Link to v1: https://lore.kernel.org/r/20240206-ad7944-mainline-v1-0-bf115fa9474f@baylibre.com
