@DT bindings maintainers,
Given the ease of maintenance of DT bindings within Linux kernel source tree, I don't have a specific objection there. But can we ease DTS testing for firmware/bootloader projects by providing a versioned release package for DT bindings? Or if someone else has a better idea here please feel free to chime in.
This doesn't work for you?:

Thanks, this is certainly a good step which I wasn't aware of. Further simplification can be done to decouple devicetree source files from DT bindings.
Why?
AFAIK, DT bindings should be forwards and backwards compatible.
The same with DTS.
So if you pick up DTS or DTB from any project tree (upstream kernel or stable kernel or u-boot) then DT schema validation would ensure that corresponding DTS or DTB doesn't regress the DT bindings.
And why is this argument to decouple DTS from bindings?
Ideally, it should be more user/CI friendly if DT bindings can be easily installed alongside devicetree schema tools [1].
Does it mean you will work on this?
