Wait a second. This is all part of an MFD device. I think this whole
binding does not make sense on it's own. The DT should describe the
PMIC, not necessarily some sub-component of it. Perhaps there are sub
nodes of the PMIC node, but that would be all part of the PMIC
binding. Having sub drivers for an MFD is really a Linux problem that
doesn't belong in DT.
