For Lunar Lake, DDI-A is connected to C10 PHY, while TC1-TC3 are connected
to C20 phy, like in Meteor Lake. Update the check in intel_is_c10phy()
accordingly.
This reverts the change in commit e388ae97e2 ("drm/i915/display:
Eliminate IS_METEORLAKE checks") that turned that into a display engine
version check. The phy <-> port connection is very SoC-specific and not
related to that version.
IS_LUNARLAKE() is defined to 0 in i915 as it's expected that the
(upcoming) xe driver is the one defining the platform, with i915 only
driving the display side.

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.
