Hello Martin,

I haven't looked at your regulator driver in detail so this is not a
full review but I just noticed something so I wanted mention.

I see that you are defining these constants in your driver too (albeit
with slightly different names). These kind of constants that are
shared between the driver implementation and the Device Tree source
files should be added to include/dt-bindings/regulator/ and included
in both the driver and the DTS.

Best regards,
Javier
