Allow up to 9 phandles. 9? Sounds like a driver detail and pretty arbitrary. Is this linkage 2-way meaning 2 coupled regulators both have links to the other one? If so, then what happens when you have a high number? If not, how does one decide which regulator has this property? > +- regulator-coupled-max-spread: Max spread between voltages of coupled regulators > + in microvolts. > > Deprecated properties: > - regulator-compatible: If a regulator chip contains multiple > -- > 2.7.4 > -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
