[PATCH 0/2] Fix AD3531/AD3531R powerdown modes

[Kim Seer Paller]

The AD3531/AD3531R has different powerdown output impedance modes from
the AD3530/AD3530R. The driver currently uses the AD3530R modes (1k,
7.7k, 32k) for all variants, which is incorrect for the AD3531/AD3531R
which has 500 Ohm, 3.85 kOhm, and 16 kOhm modes per the datasheet.

This series adds the missing ABI entries for the new powerdown modes
and fixes the driver to use the correct mode strings for AD3531/AD3531R
chip variants.
