Depending on version, the voltage table might be different. Add version compatibility to the regulator information in order to select correct voltage table.

Does it match the data sheet in some way? If not, it might be better to name this something like "tps6586x_ldo4_voltages" and "tps65863_ldo4_voltages".

Why rename the macro? There's an embedded TAB before "nbits".

TPS6586X_SYS_REGULATOR(),
- TPS6586X_LDO(LDO_0, "vinldo01", ldo0, SUPPLYV1, 5, 3, ENC, 0, END, 0),...

Rather than changing all the macros and table entries, wouldn't it be much simpler to: 1) Make tps6586x_regulator[] only contain all the common regulator definitions. 2) Add new version-specific tables for each version of regulator, so tps6586x_other_regulator[] and tps65863_regulator[]. 3) Have probe() walk multiple tables of regulators, selecting which tables to walk based on version. That would result in a much smaller and less invasive diff.
