Here are some Sascha Hauer's arguments for using aliases in the dts
files:
- using aliases reduces the number of indentations in dts files;
- dts files become independent of the layout of the dtsi files
(it becomes possible to introduce another bus {} hierarchy between
a toplevel bus and the devices when you have to);
- less chances for typos. if &i2c2 does not exist you get an error.
If instead you duplicate the whole path in the dts file a typo
in the path will just create another node.
