Viresh Kumar 579c49efdf PM / OPP: Reword binding supporting multiple regulators per device ... On certain platforms (like TI), DVFS for a single device (CPU) requires configuring multiple power supplies. The OPP bindings already contains binding and example to explain this case, but it isn't sufficient. - There is no way for the code parsing these bindings to know which voltage values belong to which power supply. - It is not possible to know the order in which the supplies need to be configured while switching OPPs. This patch clarifies on those details by mentioning that such information is left for the implementation specific bindings to explain. They may want to hardcode such details or implement their own properties to get such information. All implementations using multiple regulators for their devices must provide a binding document explaining their implementation.
