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. > And not a biggie, but I wonder if the changes to these two files should be > in separate patches, due to omapdss-boot-init going away. Well, probably > doesn't matter. 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 :) Regards, Tony [0] git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap.git omap-for-v5.7/dss-probe [1] https://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap.git/commit/?h=omap-for-v5.7/dss-probe&id=cef766300353613aa273791f70b3125d1f0420ae _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
