Subject: [PATCH v5 0/4] Adding usb2.0 host-phy support for exynos5250

Changes from v4:
 - Moved architecture side changes out of this patch-set.
 - Added support for multiple usbphy phandle parsing and
   doing all pmu_isolation() and phy_cfg_sel() related changes
   in samsung-usbphy driver only instead of architecture
   as in v4 patch-set.
 - Removed unnecessary multi line definitions for macros.

Changes from v3:
 - Moved enums S5P_USB_PHY_DEVICE, S5P_USB_PHY_HOST from machine to file
   include/linux/usb/samsung_usb_phy.h as USB_PHY_TYPE_DEVICE and
   USB_PHY_TYPE_HOST to make it more generic. Further resolve its
   dependencies.
 - Introduced a function 'samsung_usbphy_set_type()' which takes
   care of setting up the phy_type: HOST/DEVICE. This function
   can be called by host/otg drivers to setup phy_type prior to
   handling the respective PHYs.
 - Added an error-path for HOST type phy in s5p_usb_phy_pmu_isolation()
   for 'mach-s3c64xx'.
 - Moving to PHY driver as default for ehci-s5p and ohci-exynos, and only
   when failed fall back to plat-data.
 - Added samsung_usbphy_set_type() prior to doing usb_phy_init() or
   usb_phy_shutdown() so that appropriate PHY gets init or shutdown.

Based on patches for samsung-usbphy driver:
