[PATCH v3 0/3] iio: dac: ltc2632: add support for LTC2654 DAC family

[David Marinović]

From: David Marinovic <david.marinovic@xxxxxxxx>

Greetings!

This is v3 of the LTC2654 DAC support patch series.

The LTC2654 is a quad-channel, 16-/12-bit DAC with internal
reference voltage and SPI interface, sharing the same 24-bit
SPI protocol as the LTC2632/2634/2636 family.

The LTC2654L-16 variant was tested on a Phytec phyCORE-STM32MP1
board with the DAC connected via SPI1. The driver probes successfully
and all 4 channels are accessible via IIO sysfs.

Changes in v3:
- Patch 1 unchanged
- DT bindings use fallback compatibles for LTC2654-L12 and
  LTC2654-H12, which are register-compatible with LTC2634-L12
  and LTC2634-H12
- LTC2654-L16 and LTC2654-H16 keep separate compatible strings
  as no existing compatible supports 16-bit resolution
- 12-bit variants reuse existing LTC2634 chip_info structures,
  so only two new chip_info structures are added for 16-bit variants


David Marinovic (3):
  iio: dac: ltc2632: drop enum and use individual chip_info objects
  dt-bindings: iio: dac: ltc2632: add LTC2654 compatible strings
  iio: dac: ltc2632: add support for LTC2654 DAC family
