Devicetree was around long before their company had ever started doing the allwinner. It might not have been used in ARM yet, but it was used in a number of other architectures, making it the obvious choice for doing the same thing on more architectures. > [bear in mind that if this kind of thing isn't said, they risk just > continuing to make the sunxi community's life absolute hell by > continuing to work in isolation and continuing to duplicate drivers > etc. etc. ] That is their problem (and their customers). > * work is being done by the free software community, they are > beginning to integrate allwinner's work into the upstream kernel, and > you (allwinner) will begin to see this when you get round to doing > linux kernel 3.9 If something is popular enough, people will work on getting it supported, where supported means done properly. > * allwinner and the linux and sunxi community therefore need to work > closer together, we propose: > > * {insert proposals here} How about allwinner simply tries to help with the activity already taking place for getting everything working with devicetree. That probably means doing work to their tools to generate devicetree files from their FEX files, if they really like FEX (and think their customers like FEX). > 3 days left on the clock. Who cares what your deadline is.
