Hi, I'm new here and relatively new to working with Yocto (creating my own layers anyways). I'm working on developing a SOM platform based on Renesas RZ series of MPUs.
I've followed the guide on Digikey by Shawn Hymel to learn about device tree patching ( https://www.digikey.ca/en/maker/projects/intro-to-embedded-linux-part-5-how-to-enable-i2c-in-the-yocto-project/6843bbf9a83c4c96888fccada1e7aedf ). I assume many of you know about it as well. It does a good job in describing how to add changes in a dts file. In the example, a i2c5 node is added in the dts, overwriting what had been defined in the original dtsi file and I'm doubting the cleanliness of it. Would it not be better, to patch the node in the dtsi file and add the required changes there instead of adding them to the dts file essentially overwriting what was set previously? I imagine this will essentially lead to two nodes being defined with the same name, the latter just overwriting the former, is that so? How would one go about patching the dtsi and making sure that the patch is applied before ther file is included? Thank you all, Mistyron
