iio: dac: ad3530r: Add driver for AD3530R

kseerp · kseerp · commit ddd710f3eefc · 2024-12-20T23:37:15.000+08:00
The AD3530R/AD3530 are low power, 8-channel, 16-bit, buffered voltage
output, DACs that include a 2.5V internal reference (disabled by
default), and a gain bit field, resulting in a full-scale output span
of 2.5V (gain = 1) or 5V (gain = 2) for a reference voltage of 2.5V.
