We want to remove the use of pm_runtime_irq_safe() from serial drivers to allow making PM runtime handling generic. Let's simplify things by disabling PM runtime autoidle for omap-serial as this driver has been deprecated for years because of the 8250_omap driver. There are still some omap-serial users that seem to hang on to it for some unknown rs485 reasons it seems. But presumably those folks do not need PM runtime autoidle with omap-serial, and hopefully can just move to using 8250_omap driver instead. For 8250_omap driver, we will eventually move to use generic serial layer PM based on patches done by Andy Shevchenko to remove pm_runtime_irq_safe() usage.

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.
