OK thank you. I've pushed out omap-for-v5.7/dss-probe which has just
this commit against v5.6-rc1 [0][1]. Let's consider commit cef766300353
("drm/omap: Prepare DSS for probing without legacy platform data")
immutable so we can both merge it in as needed.
I have not added any tag yet as it seems that we could add also
apply Sebastian's few preparatory dts changes to this branch when
ready.

Hmm yeah good reason to put every change into a seprate patch
for future. I really did not expect this to conflict with anything
after years of no changes :)
