Most of MMIO accesses from intel_display_irq.c are currently done via uncore_*() functions instead of the display-specific ones, namely intel_de_*(). Because of that, DMC wakelock ends up being ignored and some invalid MMIO accesses are performed while display is in dynamic DC states. Thus, update the display IRQ code to use the intel_de_*() MMIO functions. After this change, we are left with some IRQ-specific functions that still use the unwrapped uncore_*() functions (i.e. gen2_irq_init, gen3_irq_reset and gen2_assert_iir_is_zero). We will deal with them in an upcoming change.

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.
