Is this actually controlling VMMC though, or is it some other control? If it's not controlling VMMC then it shouldn't say that it is. > I don't know if something similar can be done done in SPI case, but > I'm sure this is not the first your-so-called regulator misuse. It's not the first but that doesn't make controlling something other than a regulator through the regulator API any less broken.
