From 25cf25073a4e1e0563c288908481f10f98acb19a Mon Sep 17 00:00:00 2001 From: Mathias Nyman Date: Tue, 24 Apr 2012 11:02:49 +0100 Subject: gpio: add MSIC gpio driver Add gpio support for Intel MSIC chips found in Intel Medfield platforms. MSIC supports totally 24 GPIOs with 16 low voltage and 8 high voltage pins. Driver uses MSIC mfd interface for MSIC access.
