As there are no upstream drivers for VED or ISP let's just assert that they are power gated. Otherwise they would prevent s0ix entry. For ISP this is only relevant when it is not exposed as a PCI device and instead is a subordinate of the gunit. When exposed as a PCI device it will be handled by the atomisp2_pm driver. On my VLV FFRD8 board the firmware power gates both of these by default. Let's assume that is always the case and just WARN if we ever encounter something different.

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.
