From e61b170139225ccb808eb98a047dd2a8d3af830d Mon Sep 17 00:00:00 2001 From: Jonghun Han Date: Thu, 21 Jul 2011 15:46:26 +0900 Subject: ARM: EXYNOS4: Add platform device and helper functions for FIMD This patch adds platform device s5p_device_fimd0 for EXYNOS4 FIMD0. EXYNOS4 has two FIMDs(FIMD0, FIMD1). FIMD1 will be added later. Some definitions used to enable EXYNOS4 FIMD0 are added.
