I want to see where all these new drm_panel_* functions would be called
in intel_dsi.c.
Also, this patch touches drm core, not i915. You need to send this kind
of stuff to dri-devel at lists.freedesktop.org to get them merged,
preferably Cc'ing the relevant maintainers (try
scripts/get_maintainer.pl). But for that, I think you need to have the
use case and the in-kernel user as well, so please send the intel_dsi.c
patch too.
BR,
Jani.
