This patch addresses Interrupts from south display engine (SDE). ICP has two registers - SHOTPLUG_CTL_DDI and SHOTPLUG_CTL_TC. Introduce these registers and their intended values. Introduce icp_irq_handler(). The icp_irq_postinstall() takes care of enabling all PCH interrupt sources, to unmask them as needed with SDEIMR, as is done done by ibx_irq_pre_postinstall() for earlier platforms. We do not need to explicitly call the ibx_irq_pre_postinstall(). Also, while changing these, s/CPT/PPT/CPT-CNP comment. v2: - remove redundant register defines.(Lucas) - Change register names to be more consistent with previous platforms (Lucas) v3: -Reorder bit defines to a more appropriate location. Change the comments. Confirm in the commit message that icp_irq_postinstall() need not go to ibx_irq_pre_postinstall() and ibx_irq_postinstall() as in earlier platforms.

README
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.
