5 This text describes the regulator interface for consumer device drivers.
9 1. Consumer Regulator Access (static & dynamic drivers)
12 A consumer driver can get access to its supply regulator by calling ::
14 regulator = regulator_get(dev, "Vcc");
17 then finds the correct regulator by consulting a machine specific lookup table.

21 To release the regulator the consumer driver should call ::
