Chnages in v2: - Removed setting of SYSREG registers and moved to system.c. - Enabling and Disabling of USB_PHY_CTRL was moved to single function. Changes in v3: - Removed function to set PS_HOLD as it was not required for USB. - Renamed power_enable_usb_phy and exynos5_enable_usb_phy to set_usb_phy_ctrl and exynos5_set_usb_phy_ctrl. - Added defination for POWER_USB_HOST_PHY_CTRL_DISABLE.

We have usb device also. How about usbhost_phy instead of usb_phy?

- struct exynos5_power *power =
