The Turing RK1 contains 3 different USBs: - USB0: USB 2.0, OTG - USB1: USB 3.0, host - USB2: USB 2.0, host This patch activates the necessary DT nodes to enable all 3 buses. Future work will be needed on USB0: it is not USB3-capable, so the USB0 controller needs to be told that there is no USB3 port. Per Jonas's suggestion, the USBDP0 node is given a `rockchip,dp-lane-mux` property that tells the USBDP driver that USBDP0 is not involved in USB so that it can make the necessary configuration changes in hardware. Technically, this is USB *controller* configuration, not *PHY* configuration, so the underlying code may be moved in the future to the USB controller driver instead, freeing up the (software) dependency on USBDP0. A TODO comment is added to explain this.

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 reStructuredText 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.
