I rather dislike some of the property descriptions using PMIC version
numbers to distinguish between peripheral versions and others using
WLEDx version numbers.

Could the property description be rephrased to use WLED3/4/5 terminology
instead?

Similar thing here, is PMI8998 simply a synonym for WLED4 or there
something special about the PMIC versioning that requires it to be used?
