Thanks for this.
I have submitted v4 patch-set in this series:
http://www.spinics.net/lists/linux-usb/msg73977.html
This again contains some arch changes. I can minimize the arch support as
far as possible.
Possibly i can put up following changes further in v4.
 - Remove arch changes from [PATCH v4 1/5] ARM: EXYNOS: Update & move
usb-phy types to generic include layer

Small arch changes in [PATCH 2/5] usb: phy: samsung: Add host phy support
to samsung-phy driver,
in the same series (i missed v4 suffix in this :-( comes as a result of
Praveen Paneri's patches
in the series http://www.spinics.net/lists/linux-usb/msg73518.html, to
prevent build-break.

Kukjin can help Ack-ing with [PATCH v4 3/5] ARM: Exynos5250: Enabling
samsung-usbphy driver, since
this is machine specific patch.

Will this be fine ? Please suggest.
