As you may know, there is exynos chip that has two display controllers. So it is possible to compose display pipe lines at same time like below,
fimd0-----bridges..------Panel fimd1-----maybe bridges..-----CPU Panel
How we can care such pipelines without component? Of course, it would be possible somehow but I'm not sure there could be better and more generic way than super device.
And super device will make existing dtb broken but this time it might be good opportunity to more generic way before more users use existing dt.
There has been a discussion ongoing about how to best represent display (and capture) stuff in DT using graphs, which you may wish to consider looking at. That discussion never reached any kind of conclusion before the merge window, but it does need to reach a conclusion for the next window.
