commit30963b2f75upstream. The following message is seen during boot and the activation of console port gets delayed until normal serial ports activation. [ 0.001346] irq: no irq domain found for pic@930 ! The console port doesn't need irq, perform irq reservation later, during cpm_uart probe. While at it, don't use NO_IRQ but 0 which is the value returned by irq_of_parse_and_map() in case of error. By chance powerpc's NO_IRQ has value 0 but on some architectures it is -1.

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.
