[PATCH v2 0/3] iio: dac: ltc2632: add support for LTC2654 DAC family

[David Marinović]

From: David Marinovic <david.marinovic@xxxxxxxx>

Greetings!

I have mangled the first cover letter which may have caused confusion.
It's my first time submitting a kernel patch so apologies in advanced.

This is v2 of the LTC2654 DAC support patch series, addressing
review feedback from Andy Shevchenko and Krzysztof Kozlowski.

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 has been tested on a Phytec phyCORE-STM32MP1
board with the DAC connected via SPI1. The driver probes successfully
and all 4 channels are accessible via the IIO sysfs interface.

Changes in v2:
- Added refactor patch dropping the enum and using individual
  chip_info objects as requested by Andy Shevchenko
- DT bindings patch now comes before the driver patch
- DT bindings commit message now describes hardware not driver
- DT bindings patch tested with make dt_binding_check and
  scripts/checkpatch.pl --strict with no errors or warnings

Question for Krzysztof Kozlowski. You mentioned "Several look compatible
to me, so express it with fallback and drop unneeded entries in the driver."
Does this mean a complete refactor of the existing entries?
