Hi Amelie,

thanks a lot for your patches!

So I take it that the department creating the STMPE
"ST MPE" or "ST Microelectronics MultiPurpose Expander"
Now created a new set of circuits?

Can we first establish whether this new family is really so
different from STMPE that it really needs a new driver in
MFD and GPIO (and I guess pin control as well)?

I would be annoyed to see later that it is just a few bytes
separating it from the STMPE, in that case I think it is
better to just reuse/improve the good old stmpe driver
and take it from there.

Yours,
Linus Walleij
