I guess it is because: PMBUS_REGULATOR_STEP("buck", 0, MPQ7932_N_VOLTAGES, creates regulator name as buck+id (so buck0). However as Rob pointed out, driver can handle buck for this variant. We want the bindings to be independent from Linux implementation and this patch here adds such dependency. Therefore I still believe this should be just "buck", unless the datasheet says it is "buck0". Which I doubt. Best regards, Krzysztof
