I don't know how many different panels (each with different powering It would be sensible to make sure that the framework is done in such a way that drivers can use it - there will be drivers (perhaps not display ones) that have a known power sequence and which could benefit from the ability to use library code to implement it based on the user simply supplying named resources.
