 * Several regulators may be controlled via external signals instead of via

14
 * software. These constants describe the possible signals for such regulators

15
 * and generally correspond to the respecitve on-chip pins.

16
 *

17
 * S2MPG10 regulators supporting these are:

18
 * - buck1m .. buck7m buck10m

19
 * - ldo3m .. ldo19m

20
 *

21
 * ldo20m supports external control, but using a different set of control

22
 * signals.

24
 * S2MPG11 regulators supporting these are:

25
 * - buck1s .. buck3s buck5s buck8s buck9s bucka buckd

26
 * - ldo1s ldo2s ldo8s ldo13s
