The AD5710R (16-bit) and AD5711R (12-bit) are 8-channel, low-power,
configurable current/voltage output DACs with an on-chip 2.5V reference.
Each channel can be independently configured as a voltage output
(0V to VREF or 0V to 2xVREF) or a current output (0mA to 50mA).

This series adds support for these parts:
 - ABI documentation for the high_z powerdown mode and the current-output
   powerdown attributes
 - device tree bindings for the AD5710R/AD5711R
 - basic IIO DAC driver, supporting per-channel voltage/current output
   selection, per-channel powerdown, software or hardware (LDAC) DAC
   updates, optional output range doubling, internal or external
   reference, and hardware reset (with a software-reset fallback).

Changes in v2:
- Drop the standalone ad5710r driver and fold AD5710R/AD5711R support
  into the existing ad3530r driver.
- Add a preparatory patch parameterizing the DAC resolution in ad3530r
  so the 12-/16-bit AD5711R/AD5710R can reuse the raw/scale paths.
- ABI: drop the "high_z" powerdown mode, which is a synonym of the
  existing "three_state" and use "three_state" instead.
