Look through the whole controller list when mapping device tree phandles to controllers instead of stopping at the first one. Each controller is intended to only contain one kind of mailbox, but some devices (like Tegra HSP) implement multiple kinds and use the same device tree node for all of them. As such, we need to allow multiple mbox_controllers per device tree node. Signed-off-by: Mikko Perttunen <mperttunen@nvidia.com> Signed-off-by: Jassi Brar <jaswinder.singh@linaro.org>
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.
