If an USB port is an OTG port, then we should add the usb-role-switch property. Otherwise XUSB setup fails and therefore padctl is unable to set up the ports. This leads to broken USB and PCIe ports. Add the usb-role-switch properties to Tegra124 device-trees to fix the problem. The error message shown without this patch is e.g: usb2-0: usb-role-switch not found for otg mode [digetx@gmail.com: improved commit message] Tested-by: Thomas Graichen <thomas.graichen@gmail.com> # T124 Nyan Big Signed-off-by: Stefan Eichenberger <stefan.eichenberger@toradex.com> Signed-off-by: Dmitry Osipenko <digetx@gmail.com> Signed-off-by: Thierry Reding <treding@nvidia.com>
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.
