[PATCH 0/2] iio: dac: add support for AD5413

[Bruce Tsao via B4 Relay]

This series adds support for the Analog Devices AD5413: a single-channel,
14-bit, serial-input DAC with software-selectable voltage (+/-10.5 V) and
current (0-24 mA) outputs. The SPI interface runs in mode 1 and carries a
CRC-8 on every frame, which the device has enabled out of reset.

Patch 1 documents the device-tree binding; patch 2 adds the IIO driver.

Tested on an EVAL-AD5413SDZ with a Raspberry Pi 5 and an NXP i.MX93 FRDM
board (probe, voltage- and current-output, scale/offset, powerdown/resume).
