Both these models require an enable GPIO so we can safely assume that if the property is not there, then we should try to get the power sequencer. Due to how the pwrseq lookup works - checking the provider at run-time - we cannot really do it the other way around as we'd get stuck forever on -EPROBE_DEFER. If the relevant OF node does have the 'enable-gpios' property, we fallback to the existing code for backward compatibility with older DTs.
