Subject: [RFC PATCH 4/6] ARM: dts: OMAP: Add phandle to bind PHY with USB controller

Added a phandle in the dt node for usb_otg to bind the PHY with the USB
controller and also updated the documentation with the binding information.

Signed-off-by: Kishon Vijay Abraham I <kishon@...com>

I'll add this patch in this series "usb: musb: add driver for control module"
which contains the dt data to get MUSB working in dt boot in OMAP platforms.
