From 57ae1605c0f511bca212787d28d79a3f82c0a7f9 Mon Sep 17 00:00:00 2001 From: Jingoo Han Date: Thu, 10 Oct 2013 16:41:19 +0900 Subject: [PATCH] USB: ehci-s5p: Remove non-DT support The non-DT for EXYNOS SoCs is not supported from v3.11. Thus, there is no need to support non-DT for Exynos EHCI driver. The 'include/linux/platform_data/usb-ehci-s5p.h' file has been used for non-DT support. Thus, the 'usb-ehci-s5p.h' file can be removed.
