After considering the feedback received regarding the context of the 
leaf driver for max5970, it has been recommended to specifically use 
"max5970" instead of a general designation like "max597x." However, for 
support related to max5978, the documentation can be referred to.

Therefore, this change is necessary in order to unblock the leaf driver 
and address the feedback received.
