This should be bool and the related changes like using true/false.
Actually, on reviewing this code even more, I really suggest you first
do some clean up to this driver and then just change this to:
int nr_ldo;
Then use that instead of LDO_NB.
buck_configured[] should be bool as well.

The tps65224_multiphases[] array is never used except to get the
ARRAY_SIZE(). Neither of these are necessary. Just use
multi_regs[multi].supply_name instead.

Unrelated to your patch but this should be:
if (strcmp(npname, tps6594_multiphases[multi]) == 0) {
The == means that the strings are equal. No need for a delta variable.

No need for size_add/mul(). These are small constants so it's not
going to integer overflow.
The other suggestion here would be to do a clean up of the driver first
so instead of marking the last buck_configured[4] = 1; we would instead
say "nr_buck = 4;" Then the math become easier and we can remove the
comments and the confusing subtractions.
if (tps->chip_id == LP8764) {
nr_buck = 4;
nr_ldo = 0;

nr_buck = ARRAY_SIZE(tps65224_buck_regs);

There are too many unrelated white space changes in this patch.

Now that we have introduced a nr_ldo variable we can delete the
/* LP8764 doesn't have LDO */ comment and the if LP8764 statement and
the if (ldo_configured[i] == 1) condition.
for (i = 0; i < nr_ldo; i++) {
rdev = devm_regulator_register(&pdev->dev, &ldo_regs[i], &config);
The BUCK loop would only loop nr_buck times as well.

Declare an irq_types pointer.

Unrelated.
