On i.MX95 platform, USB wakeup setting is controlled by HSIO Block Control: HSIO Block Control Overview: - The HSIO block control include configuration and status registers that provide miscellaneous top-level controls for clocking, beat limiter enables, wakeup signal enables and interrupt status for the PCIe and USB interfaces. The wakeup function of HSIO blkctl is basically same as non-core, except improvements about power lost cases. This will add the wakeup setting for HSIO blkctl on i.MX95. It will firstly ioremap hsio blkctl memory, then do wakeup setting as needs.

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 reStructuredText 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.
