From 95d6791b4f8aad51caea657236234f21b50a4559 Mon Sep 17 00:00:00 2001 From: Yauhen Kharuzhy Date: Thu, 6 Jan 2011 13:04:33 +0900 Subject: ARM: S3C24XX: Add address map and clock definitions for HSMMC0 Define maps for HSMMC devices. S3C2443 has one HSMMC device with base address 0x4A800000. S3C2416 has HSMMC0 at 0x4AC00000 and HSMMC1 at 0x4A800000. So suppose that S3C2443 has only HSMMC1. Define clock for hsmmc0 device and register it.
