For delays longer than 20ms [um]delay isn't recommended. pm80xx_chip_soft_rst starts off with a 500ms delay before it even gets around to checking for the results of the reset. As long as it's at least 500ms it doesn't matter what the scheduler is doing. The delay in the pm8001_exec_internal_task_abort does nothing, and theory is this is a delay to avoid a double-free.

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.
