Hi all,
This series update the STMPE MFD driver to use of_compatible to probe for
sub-functions instead of using hardcoded names.  Matching by name does not seems
in general a good idea, in this specific case it is even worst since the node
name are not compliant to the current naming convention (they are not generic
and they do include underscores), and because of that recently
we had a regression introduced [1].

This change was suggested by Ahmad Fatoum [2].

[1] commit 56086b5e ("ARM: dts: imx6qdl-apalis: Avoid underscore in node name")
