i did find it very funny to learn that Linus did not understand why there
were so many ARM developers at the Cambridge Linux Conference
back in... when was it... 2007? it coincided with UKUUG at the time.
he's famously on record as saying "why are there so many of you?
go away, choose one representative and come back with just one
likewise, i _am_ on record as pointing out a long long time ago that
device-tree will not stop the proliferation or complexity of developing
device drivers for ARM: it merely *moves* the proliferation and
complexity... into dtsi files....
the only big advantage of dtb files (binary compiled) is *IF* the
decision is made to respect dtb files and treat them as inviolate
and supported forever without needing recompiles, you stand a
chance of being able to upgrade linux kernels *without* replacing
the dtb file. however i seriously doubt that the stringent testing
needed to make that work will ever be put in place. oh well.
