Moving the dts directory is fine (though that is really up to SoC maintainers). Changing compatible strings is not. It is not about the patch split. It is an ABI. There are exceptions though. Generally that is if there is no one with the h/w or the current .dts is so incomplete that anyone using the h/w will need to update their DTB anyways. Rob
