Subject: [PATCH v1 0/6] USB: Add support for multiple PHYs of same type

This patch series adds support for adding multiple PHY's (of same type).
The binding information has to be present in the PHY library (otg.c) in
order for it to return the appropriate PHY whenever the USB controller
request for the PHY. So added a new API usb_bind_phy() to pass the binding
information. This API should be called by platform specific initialization
code.

So the binding should be done something like
usb_bind_phy("musb-hdrc.0.auto", 0, "omap-usb2.1.auto"); specifying the USB
controller device name, index, and the PHY device name.
I have done this binding for OMAP platforms, but it should be done for
all the platforms.

After this design, the phy can be got by passing the USB controller device
pointer and the index.

Developed this patch series on
git://git.kernel.org/pub/scm/linux/kernel/git/balbi/usb.git xceiv
after applying "usb: musb: add driver for control module" patch series
and "ARM: dts: omap: add dt data for MUSB"

Did basic enumeration testing in omap4 panda and omap3 beagle.

Kishon Vijay Abraham I (6):
  usb: otg: Add an API to bind the USB controller and PHY
  usb: otg: utils: add facilities in phy lib to support multiple PHYs
    of same type
  ARM: OMAP: USB: Add phy binding information
  drivers: usb: musb: omap: make use of the new PHY lib APIs
  usb: otg: add device tree support to otg library
  USB: MUSB: OMAP: get PHY by phandle for dt boot
