The latent IRQs are IRQs that have occurred when the system was down in deep sleep and the GPIO block was powered off. The PRCMU (power reset and control unit) knows which GPIO line offset fired an IRQ to wake the system up (if so desired) and this second IRQ was used to replay the action when the system came back online after suspend(). This is now known to be the wrong approach to solve this problem: in a patch series Lina Iyer has suggested to instead make it possible to model the IRQs as hierarchical with double parents. Also the current device trees do not contain the right information to make this code work, the latent IRQ is not specified nowadays giving noise like this in the console: [ 0.612168] gpio 8012e000.gpio: IRQ index 1 not found [ 0.622523] gpio 8012e080.gpio: IRQ index 1 not found Let's delete the latent IRQ code and reimplement it properly when we need it.

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.
