In order to probe display subsystem (DSS) components with ti-sysc interconnect target module without legacy platform data and using devicetree, we need to update dss probing a bit.
In the device tree, we will be defining the data also for the interconnect target modules as DSS really is a private interconnect. There is some information about that in 4460 TRM in "Figure 10-3. DSS Integration" for example where it mentions "32-bit interconnect (SLX)".
The changes we need to make are:
Parse also device tree subnodes for the compatible property fixup
Update the component code to consider device tree subnodes

This is needed for dropping DSS platform data that I'll be posting seprately. If this looks OK, can you guys please test and ack?

This doesn't conflict with drm-next (with Laurent's recent patches), so it should be fine for you to have this in your branch.
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 :)

Tony
