From 8f5260c8c1a1f9b25dfedd5ca749e4faef1b3eb9 Mon Sep 17 00:00:00 2001 From: Lothar Waßmann Date: Tue, 26 Oct 2010 14:28:31 +0200 Subject: ARM: i.MX IOMUX-V3 replace struct pad_desc with bitmapped cookie MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The following patch is a first step to convert the 'struct pad_desc' to a bitmapped cookie to facilitate adding platform specific pullup or drive strength definitions to existing pad definitions without need to rewrite the complete pad def. The patch wraps 'struct pad_desc' in an opaque data type and introduces macros to access the individual members. This patch does not constitute any functional change!
