From f7074ab348e29c8068a2daaaf89920aebc903a98 Mon Sep 17 00:00:00 2001 From: Sylwester Nawrocki Date: Sun, 18 Aug 2013 16:14:27 -0300 Subject: [PATCH] [media] s5p-jpeg: Add initial device tree support for S5PV210/Exynos4210 SoCs This patch enables the JPEG codec on S5PV210 and Exynos4210 SoCs. There are some differences in newer versions of the JPEG codec IP on SoCs like Exynos4x12 and Exynos5 series and support for them will be added in subsequent patches.
