A number of us had a face-to-face meeting in Dublin last week to talk about DT maintainership and the fact that it simply isn't working right now. Neither Rob nor I can keep up with the load and there are a lot of poorly designed bindings appearing in the tree.
Device tree binding maintainership needs to be split off to a separate group, and we've started with a few people willing to help, Pawel Moll, Mark Rutland, Stephen Warren and Ian Campbell.
(BTW, even though I've already sent a patch adding that group MAINTAINERS, this is not set in stone. Anyone else wanting to help maintain should volunteer)
Another thing discussed is that we need to start validating DT schema with an extension to dtc. Tomasz Figa has volunteered to do this work and has support from his employer to spend time on it. What I'm hoping to have is that the DT schema will get checked as part of the dts build process so that any DT file that doesn't match the documented schema will get flagged, and that the schema files will be human readable and will double as documentation.
There is not yet any process for binding maintainership. We talked about a few ideas, but they really need to be hashed out here on the mailing list. A couple of the questions:
- How are bindings allowed to be merged? Through subsystem trees, or only through the bindings tree? - Through the bindings tree is more work but it will provide more control. - Through subsystem trees means drivers and bindings get merged together. - If we have a schema tool that reports errors on missing or unapproved schema, then spliting the driver from the binding won't matter that much. - Do we need to differentiate between 'staging' and 'stable' bindings? - What is the schedule for splitting the bindings and .dts files out of the kernel? - Ian Campbell is maintaining a DT bindings and .dts mirror tree which should eventually become the 'master' for merging DT bindings.
