Call the parent driver pcode functions through the parent interface function pointers instead of expecting both to have functions of the same name. In i915, add the interface to existing intel_pcode.[ch], while in xe move them to new display/xe_display_pcode.[ch] and build it only for CONFIG_DRM_XE_DISPLAY=y. Do not add separate write and write_timeout calls in the interface. Instead, handle the default 1 ms timeout in the intel_parent.c glue layer. This drops the last intel_pcode.h includes from display, and allows us to remove the corresponding xe compat header. v2: initialize .pcode in i915 Reviewed-by: Michał Grzelak <michal.grzelak@intel.com> Link: https://patch.msgid.link/20260126112925.2452171-1-jani.nikula@intel.com Signed-off-by: Jani Nikula <jani.nikula@intel.com>
