Everything about the file is about display, and mostly about types related to display. Move under display/ as intel_display_types.h to reflect the facts. There's still plenty to clean up, but start off with moving the file where it logically belongs and naming according to contents. v2: fix the include guard name in the renamed file Reviewed-by: Chris Wilson <chris@chris-wilson.co.uk> Signed-off-by: Jani Nikula <jani.nikula@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20190806113933.11799-1-jani.nikula@intel.com
