Summary

The time to switch from hardcoded device configurations to device trees has come. This chapter gave you all the bases to handle device trees. Now you have the necessary skills to customize or add whatever node and property you want to the device tree and extract them from your driver.

In the next chapter, we will discuss the I2C driver, and use the device tree API to enumerate and configure our I2C devices.
