[$] Device trees as ABI
Last week's device tree article introduced
the ongoing discussion on the status of device tree maintainership in the
kernel and how things needed to change. Since then, the discussion has
only intensified as more developers consider the issues, especially with
regard to the stability of the device tree interface. While it seems
clear that most (but not all) participants believe that device tree
bindings should be treated like any other user-space ABI exported by the
kernel, it is also clear that they are not treated in this way currently.
Those seeking to change this situation will have a number of obstacles to
overcome.
