The default value of 5ms will use GPIO hardware based debounce clocks that will keep L4PER from idling consuming about extra 30mW. Use a value of 10ms that is above the hardware debounce maximum of 7.95ms forcing software based debouncing. This allows droid4 to enter PER retention during idle as long as UARTs are idled and USB modules unloaded or unbound. Note that there seems to be a pending issue with having droid 4 enter core retention during idle where GPIO bank 1 needs to be reset late after init for some reason to not block core retention. In addition to that, we are also missing GPIO related PM runtime calls for omap4 that will be posted separately.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
