The 7216 has the new USB XHCI controller from Synopsys. While this new controller and the PHY are similar to the STB versions, the major differences are: - Many of the registers and fields in the CTRL block have been removed or changed. - A new set of Synopsys control registers, BCHP_USB_XHCI_GBL, were added. - MDIO functionality has been replaced with direct access registers in the BCHP_USB_XHCI_GBL block. - Power up PHY defaults that had to be changed by MDIO in previous chips will now power up with the correct defaults. A new init module was created for this new Synopsys USB controller. A new compatible string was added and the driver will dispatch into one of two init modules based on it. A "reg-names" field was added so the driver can more easily get optional registers. A DT bindings document was also added for this driver.

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.
