This would need to be an array of supplies, relatively few devices need only a single power supply. This is also not something that should be handled in I2C, power is not something that's uniquely needed by devices on an I2C bus.
Additional regulators can be handled in the driver, or "parent"-scheme can be used. Is not it?
Given how common it is to have multiple supplies it seems sensible to just handle that in the core - it's common to have a digital supply and an analogue supply for example. The regulator framework already has APIs for working with multiple regulators in a single call so it's not going to be much more effort on the framework side. -------------- next part -------------- A non-text attachment was scrubbed...
