Isn't this the name of the pad on the SoC, i.e. the consumer? Does the
regulator output have a more suitable name?
I don't see any references to this node and you got it "boot-on", what
happens when the regulator core tuns it off? Or this isn't an issue
until we actually try to support sdhci (guessing based on the voltages)?
