I understand the logic behind handling powering sequences in the device
driver, but as we discussed for some classes of devices this might just
not
scale. 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.

Not sure I understand what you mean, but things should be working this way 
already - regulators and PWMs are acquired by name using the standard 
regulator_get() and pwm_get() functions. GPIOs do not, AFAIK, have a way to be 
referenced by name so their number is used instead.
