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 <redacted> --- 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.
