The TPS65217 is missing of_compatible string in the mfd_cell for its
subdevices. This compatible string is necessary to use functions like
of_find_backlight_by_node in backlight.c.

This is now confusing.  Please make it clear that this part of the
documentation is now referencing the sub-node.

This shouldn't be in this patch.

I will add a Subnode properties label, to make it clearer.
