All I was saying is that when you introduce a DT property, > it should not be specific to that driver. Yes sounds like it would be a usable generic binding. Not sure that it should be called slot-name though, maybe you can use the MMC driver instance name instead? I don't think much any drivers support multiple MMC slots although it's in the original MMC spec. If setting up the generic binding is expected to take a while, you can naturally pass it in pdata while waiting for the generic binding to get merged.
