The pins associated with m_can have to have a special configuration to be able to wakeup the SoC from some system states. This configuration is described in the wakeup pinctrl state while the default state describes the default configuration. Also add the sleep state which is already in use by some devicetrees. Also m_can can be a wakeup-source if capable of wakeup.

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.
