From 45c480c9f6dbb80c7af721f451b4df5a32402899 Mon Sep 17 00:00:00 2001 From: Ajay Kumar Date: Fri, 5 Sep 2014 16:53:33 +0530 Subject: video: exynos_fimd: Add framework to disable FIMD sysmmu On Exynos5420 and newer versions, the FIMD sysmmus are in "on state" by default. We have to disable them in order to make FIMD DMA work. This patch adds the required framework to exynos_fimd driver, and disables FIMD sysmmu on Exynos5420.
