Animesh Manna 3e68928b7d drm/i915/icl: Enable DC9 as lowest possible state during screen-off
ICL supports DC5, DC6, and DC9. Enable DC9 during screen-off, and enable
DC5/6 when appropriate.

v2: (James Ausmus)
 - Also handle ICL as GEN9_LP in i915_drm_suspend_late and
   i915_drm_suspend_early
 - Add DC9 to gen9_dc_mask for ICL
 - Re-order GEN checks for newest platform first
 - Use INTEL_GEN instead of INTEL_INFO->gen
 - Use INTEL_GEN >= 11 instead of IS_ICELAKE
 - Consolidate GEN checks

v3: (James Ausmus)
 - Also allow DC6 for ICL (Imre, Art)
 - Simplify !(GEN >= 11) to GEN < 11 (Imre)

v4: (James Ausmus)
 - Don't call intel_power_sequencer_reset after DC9 for Gen11+, as the
   PPS regs are Always On
 - Rebase against upstream changes

v5: (Anusha Srivatsa)
- rebased against the latest upstream changes.

v6: (Anusha Srivatsa)
- rebased.Use INTEL_GEN consistently.
- Simplify the code (Rodrigo)

v7: rebased. Change order according to platforms(Jyoti)

v8: rebased. Change the check from platform specific to
HAS_PCH_SPLIT(). Add comment in code to be more clear.(Rodrigo)

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.
