Jonas Karlman 72c64fa2e4 phy: rockchip: naneng-combphy: Enable U3 OTG port for RK3568 
[ Upstream commit 7bb14b61b7 ]

The boot firmware may disable the U3 port early during boot and leave it
up to the controller or PHY driver to re-enable U3 when needed.

The Rockchip USBDP PHY driver currently does this for RK3576 and RK3588,
something the Rockchip Naneng Combo PHY driver never does for RK3568.
This may result in USB 3.0 ports being limited to only using USB 2.0 or
in special cases not working at all on RK3568.

Write to PIPE_GRF USB3OTGx_CON1 reg to ensure the U3 port is enabled
when a PHY with PHY_TYPE_USB3 mode is used.

README 

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.
