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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.

Drop support for non-DT systems, which hasn't been used by a mainline kernel since commit 9080b8dc ("ARM: OMAP2+: Remove legacy usb-host.c platform init code"). Specifically, since that commit usb_get_phy_dev() have always returned -ENODEV when looking up a legacy phy, something which in turn would have led to the init callback returning -EPROBE_DEFER indefinitely.
