   So, you plan to generate the source code from device tree? The device tree concept disappear after the tool finish the conversion.
   This approach is totally different from Linux which I am working with more than five years. Did you studied how device tree is used in other OS(e.g. Linux or Zephyr) and summary pros and cons for the different approach?
   I am working with Linux kernel more than ten years, the most important design decision for Linux driver from my view is just two things:
   1.Introduce the common driver model from 2000~:
      https://www.kernel.org/doc/html/latest/driver-api/driver-model/index.html
   2.Inroduce the device tree from 2010~:
      https://github.com/torvalds/linux/blob/master/Documentation/devicetree/usage-model.txt
      https://github.com/torvalds/linux/blob/master/Documentation/devicetree/booting-without-of.txt
   And give me a strong impresson how Linux combine these two piece concept in a flexiable way and fix many driver problems I found ten years ago with a a elegant solution.
   So I would sugest to study how other OS(at least Linux and Zephy) use the device tree before we start porting the device tree to NuttX.
