Looking more closely there is actually a proper binding document which
got added by Lee Jones:
commit 84e6de813b2d1bdb127943d3c8edf1c1afaa90da
Author: Lee Jones <lee.jones@xxxxxxxxxx>
Date: Mon Nov 5 16:10:34 2012 +0100
Subject: Documentation: Describe bindings for STMPE Multi-Functional
Device driver
Documentation/devicetree/bindings/mfd/stmpe.txt
Required properties:
- compatible : "st,stmpe[811|1601|2401|2403]"
