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().

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.
