So if you think we can get the panel driver upstream without the
pyra dts files I am happy to submit something for review.
But I have to fix it first.
Maybe Tomi can comment about ideas what structural changes have
been done so that it got broken since v5.7-rc1. Then it becomes
easier to fix for me. Maybe there was some rework in omapdrm/dss
which needs some change in the driver.
And what I would need to know before I start to write new code is
if is possible to operate a video mipi dsi panel with driver from
gpu/drm/panel together with omapdrm (v5.7 and later).
If this is possible it should be quite easy to mix the
old omapdrm/display driver code with e.g.:
drivers/gpu/drm/panel/panel-orisetech-otm8009a.c
BR and thanks,
Nikolaus
