Perhaps you should add a note that only the regulator component is currently supported. <snip> > new file mode 100644 > index 0000000..8c61640 > --- /dev/null > +++ b/drivers/mfd/tps65218.c > @@ -0,0 +1,281 @@ > +/* > + * TPS65218 chip family multi-function driver Instead of calling it an MFD driver (is there such a thing?)
