[PATCH 3/5] mfd/stmpe: Add support for stmpe variant 610

From: Viresh Kumar
Date: Wed Nov 16 2011 - 06:26:42 EST


STMPE610 is very much like STMPE811, except the number of gpio pins, which is 8
in 811 and 6 in 610. This patch adds support for variant 610. STMPE610 will
share most of the code with STMPE811.
