At the moment the AB8500 USB PHY driver still uses the old USB PHY subsystem instead of the generic PHY subsystem. This means that there is no explicit link between the USB controller and the USB PHY. In U-Boot the PHY driver is integrated in the generic PHY subsystem, so we need to use the typical PHY device tree bindings to specify which PHY belongs to the USB controller. Add the link between USB controller and PHY to both ste-ab8500.dtsi and ste-ab8505.dtsi. This is mainly for U-Boot for now and will just be ignored in Linux. However, if the AB8500 USB PHY driver in Linux is moved to the generic PHY subsystem at some point these device tree changes can be used as well.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
