Expose key Type-C port data in i915_display_info to make it easier to understand the port configuration and active mode, especially whether the link is in DP-Alt or TBT-Alt, without having to scan kernel logs. Tested in DP-Alt, TBT-Alt, SST, and MST. Expected output: [CONNECTOR:290:DP-2]: status: connected TC Port: E/TC#2 mode: tbt-alt pin assignment: - max lanes: 4 physical dimensions: 600x340mm ... [CONNECTOR:263:DP-5]: status: connected TC Port: G/TC#4 mode: dp-alt pin assignment: C max lanes: 4 physical dimensions: 610x350mm v2: Use drm_printer (Ville) Lock/Unlock around the printf (Imre) v3: Forward Declaration drm_printer struct (Jani) v4: Handle MST connector with no active encoder (Imre) Add a delimiter between fields and ":" after the port name (Imre) v5: Init dig_port and use it in intel_encorder_is_tc and tc_info (Imre) Move tc->port_name to a newline (Imre) v6: Use intel_tc_port_lock/Unlock (Imre) Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Cc: Imre Deak <imre.deak@intel.com> Cc: Jani Nikula <jani.nikula@intel.com> Signed-off-by: Khaled Almahallawy <khaled.almahallawy@intel.com> Reviewed-by: Imre Deak <imre.deak@intel.com> Signed-off-by: Imre Deak <imre.deak@intel.com> Link: https://patch.msgid.link/20251028190753.3089937-1-khaled.almahallawy@intel.com |

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.
