After looking more closely, the register map is the same as the AD3530R family.
I originally kept it separate because of the functional differences: per channel
VDAC/IDAC selection described in device tree via adi,ch-func, selectable 12/16 bit
resolution, and current output path. But those can be fit the existing chip_info
abstraction. Given that, I'm leaning toward extending ad3530r to support the
ad5710r/ad5711r and dropping the standalone driver. Does that direction work for
you? If so, I will do it in v2.
