[PATCH 1/2] iio: ABI: Add DAC 500ohm, 3.85kohm, and 16kohm powerdown modes
From: Kim Seer Paller
Date: Tue May 05 2026 - 00:42:20 EST
Add powerdown mode entries for DACs with 500 Ohm, 3.85 kOhm, and
16 kOhm resistor to ground output impedance states. These are used
by the AD3531/AD3531R 4-channel DAC.
