From cfd701b5f3eefc98cf699143d34e8a8b737b90a5 Mon Sep 17 00:00:00 2001 From: Alison Wang Date: Mon, 27 May 2013 22:55:41 +0000 Subject: arm: vf610: Add IOMUX support for Vybrid VF610 This patch adds the IOMUX support for Vybrid VF610 platform. There is a little difference for IOMUXC module between VF610 and i.MX platform, the muxmode and pad configuration share one 32bit register on VF610, but they are two independent registers on I.MX platform. A CONFIG_IOMUX_SHARE_CONFIG_REG was introduced to fit this difference.
