Hello everyone. I have been working on submitting my GSoC23 driver [1] to be merged upstream. BeaglePlay has a specific UART that is connected to the CC1352 Co-processor. This UART is used to communicate with CC1352 co-processor. It is also used to flash stuff to this co-processor using bsl. Thus, it should be possible to disable it with an overlay and show it as a normal ttyS* device. Currently, the beagle kernel uses the following dts [3]. My driver uses this UART and thus I need to patch the devicetree. However, I am not too sure what I need to do to submit my device tree patch upstream. I read the Submitting Devicetree (DT) binding patches' doc [2], but I don't understand a few things: 1. Should I even be using device tree? Maybe there is a better method? 2. Is there some naming convention? I was thinking of `beagle,cc1352-uart` 3. Do I need a documentation entry at `Documentation/devicetree/bindings`? If yes, should it go under serial? 4. I think I am supposed to use YAML now and not txt? 5. What are the required fields in this doc file?
