This series adds an IIO driver for the Texas Instruments DAC7562, DAC7563,
DAC8162, DAC8163, DAC8562, and DAC8563 dual-channel voltage-output DACs.
These devices are pin-compatible 12-, 14-, and 16-bit variants sharing the
same 24-bit SPI command interface. Each device provides two independently
addressable output channels and includes a 2.5 V, 4 ppm/°C internal
reference that can be enabled via device tree, or an external reference
supplied through a regulator. The register and command structure differs
from already existing drivers which makes adding a new driver a
reasonable choice in my opinion.
The driver supports:
- All six device variants via a shared chip info table
- DAC updates in synchronous mode
- Configurable internal or external voltage reference
- Optional LDAC GPIO which has to be asserted permanently when using
synchronous updates.
- IIO_CHAN_INFO_RAW and IIO_CHAN_INFO_SCALE attributes per channel
Datasheet (DAC8163):

The driver was tested with a DAC8163 on a custom STM32MP157F board with
external reference enabled.
