From 5e96adec6b6bc616259d8bd64e8a80d6dfc4403a Mon Sep 17 00:00:00 2001 From: Eric Miao Date: Wed, 3 Sep 2008 09:47:42 +0800 Subject: [PATCH] [ARM] pxa/spitz: convert to use new MFP API Original patch from Dmitry Baryshkov's initial scoop gpio conversion work at http://git.infradead.org/users/dbaryshkov/zaurus-2.6.git. TODO: figure out the MFP configuration of the SSP2 which looks like to be already configured by the boot loader, though.
