From 1cda2394e95415f1469ab8eaffd081395e112551 Mon Sep 17 00:00:00 2001 From: Viresh Kumar Date: Thu, 17 Nov 2011 11:02:22 +0530 Subject: mfd: Add support for stmpe variant 610 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.
