From 26b4c8dddd98ba9f759f1986e0116adaa9dce710 Mon Sep 17 00:00:00 2001 From: Eric Miao Date: Fri, 18 Jul 2008 09:05:17 +0800 Subject: [PATCH] [ARM] pxa/poodle: convert to use the new MFP API to configure pins The MFP configuration table is reverse engineered from those magic GAFRx_{L|U} values, and it looks much better now. Also, the deprecated pxa_gpio_mode() invocations are removed.
