drm/{i915, xe}/display: pass parent interface to display probe Let's gradually start calling i915 and xe parent, or core, drivers from display via function pointers passed at display probe. Going forward, the struct intel_display_parent_interface is expected to include const pointers to sub-structs by functionality, for example: struct intel_display_rpm { struct ref_tracker *(*get)(struct drm_device *drm); /* ... */ }; struct intel_display_parent_interface { /* ... */ const struct intel_display_rpm *rpm; }; This is a baby step towards not building display as part of both i915 and xe drivers, but rather making it an independent driver interfacing with the two. v3: useless include additions dropped v2: unrelated include removal dropped Cc: Jouni Högander <jouni.hogander@intel.com> Cc: Lucas De Marchi <lucas.demarchi@intel.com> Cc: Rodrigo Vivi <rodrigo.vivi@intel.com> Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Signed-off-by: Jani Nikula <jani.nikula@intel.com> Signed-off-by: Jouni Högander <jouni.hogander@intel.com> Link: https://patch.msgid.link/20251030202836.1815680-2-jouni.hogander@intel.com

drm/{i915, xe}/display: Add display runtime pm parent interface We have differing implementations for display runtime pm in i915 and xe drivers. Add struct of function pointers into display_parent_interface which will contain used implementation of runtime pm. v2: - add _interface suffix to rpm function pointer struct - add struct ref_tracker forward declaration - use kernel-doc comments Reviewed-by: Jani Nikula <jani.nikula@intel.com> Signed-off-by: Jouni Högander <jouni.hogander@intel.com> Link: https://patch.msgid.link/20251030202836.1815680-3-jouni.hogander@intel.com
