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
