Hi Rob,

quoted

+- compatible		: must be "st,stmfts"

Seems too generic. Is this a single device?

the device is precisely called ST-Microelectronics FingerTip S
(stmfts). There are variants, but they all have the same name and
same datasheet.

Maybe I can be more specific in the description, sometimes I
omitted the 'S'.
