From e2e1338900208ab36e3b86349ffdb3eba52302f8 Mon Sep 17 00:00:00 2001 From: Leela Krishna Amudala Date: Fri, 21 Sep 2012 16:52:15 +0530 Subject: [PATCH] drm/exynos: add platform_device_id table and driver data for drm fimd Two device ids are created for exynos4-fb and exynos5-fb. Also, added driver data for exynos4 and exynos5 to pick the timing base address at runtime to write data into appropriate register address.
