More specifically, it is a description of hardware that is readable by an operating system so that the operating system doesn't need to hard code details of the machine" http://lxr.free-electrons.com/source/Documentation/devicetree/usage-model.txt#L79 "What it does do is provide a language for decoupling the hardware configuration from the board and device driver support in the Linux kernel (or any other operating system for that matter)." And like I said, we already had bindings for out of tree bindings, like this one: https://patchwork.kernel.org/patch/9275707/ Which triggered no discussion at the time (but the technical one, hence a v2, that should always be done). > - The series has code changes which [seemingly] cater for out of tree > module(s). That patch was dropped, only DT changes remains now, and do not depend of that missing patch anyway. > Clearly state in the commit message who is the user, why it's save to > do so and get an Ack from more prominent [DRM] developers. DRM is really not important here. We could implement a driver using i2c as far as the DT is concerned. FreeBSD for example uses a different, !DRM framework to support our display stack, and still uses the DT.
