I'd put the #define below the ldo4 table. This doesn't actually matter
for the preprocessor, but it makes it easier to read the code. Also an
additional blank line would help with readability.

Perhaps reduce the indentation here so there's more room in case this
ever needs to be extended?

Why the prefix "reg_"?

Perhaps instead of repeating the function calls this could be:
switch (version) {
case TPS6586XYZ:
num = ARRAY_SIZE(tps6586xyz_regulator);
table = tps6586xys_regulator;
break;
...
}
if (table)
ri = find_regulator_info(id, table, num);
That's slightly longer, but I find that to be more intuitive. Perhaps
a bit more future-proof since you only have a single call. But that's
perhaps subjective, so I'm fine with your alternative, too.
