Subject: [PATCH 0/4] Add driver for AD3530R and AD3531R DACs

The AD3530R/AD3530 is an 8-Channel, 16-Bit Voltage Output DAC, while the
AD3531R/AD3531 is a 4-Channel, 16-Bit Voltage Output DAC. These devices
include software-programmable gain controls that provide full-scale
output spans of 2.5V or 5V for reference voltages of 2.5V. They operate
from a single supply voltage range of 2.7V to 5.5V and are guaranteed to
be monotonic by design. Additionally, these devices features a 2.5V,
5ppm/°C internal reference, which is disabled by default.

The AD3531R/AD3531 is not yet released, so the only available datasheet
for now is the AD3530R/AD3530. The only differences between the two is
the number of channels, and register addresses of some registers.
