[ Upstream commite5deb8f76e] The uarts should be tagged with SYSC_QUIRK_SWSUP_SIDLE instead of SYSC_QUIRK_SWSUP_SIDLE_ACT. The difference is that SYSC_QUIRK_SWSUP_SIDLE is used to force idle target modules rather than block idle during usage. The SYSC_QUIRK_SWSUP_SIDLE_ACT should disable autoidle and wake-up when a target module is active, and configure autoidle and wake-up when a target module is inactive. We are missing configuring the target module on sysc_disable_module(), and missing toggling of the wake-up bit. Let's fix the issue to allow uart wake-up to work.

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.
