mainlining shenanigans
04f41c68f1
There are many instances of PHYs that depend on a switch to supply a
resource (Eg: interrupts). Switches also expects the PHYs to be probed
by their specific drivers as soon as they are added. If that doesn't
happen, then the switch would force the use of generic PHY drivers for
the PHY even if the PHY might have specific driver available.
fw_devlink=on by design can cause delayed probes of PHY. To avoid, this
we need to set the FWNODE_FLAG_NEEDS_CHILD_BOUND_ON_ADD for the switch's
fwnode before the PHYs are added. The most generic way to do this is to
set this flag for the parent of MDIO busses which is typically the
switch.

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.
