From 483e49bfd775adb15102418a72c7fb02ef51fd79 Mon Sep 17 00:00:00 2001 From: Joonyoung Shim Date: Wed, 21 Jan 2015 13:51:32 +0900 Subject: [PATCH] EXYNOS5: Add function to enable exynos5420 usbdev phy ctrl Exynos5420 has different registers with other exynos5 SoCs to control usb device phy, so need separated function to enable exynos5420 usb device phy.
