No that is not what I am proposing.  And never have.  I support keeping the MFD
devices in the MFD directory and only pulling out the single function devices as we have
debated over and over again.

Change was copy and pasted don't know why I need to rephrase the same exact
change only for a different part but I can modify it.

I do see what I can update here.  As you said I will fix up the ti-lmu binding in
such a way that the dedicated LED driver bindings point to the common binding for the TI-LMU
framework.
