chapter2-devicetree-basics.rst and chapter1-introduction.rst refer to an Appendix A which does not exist:

".. note:: Most devicetrees in :abbr:DTS (Device Tree Syntax) (see Appendix A) will not
contain explicit phandle properties. The DTC tool automatically inserts
the phandle properties when the DTS is compiled into the binary DTB
format."

In chapter2-devicetree-basics.rst I would have expected an example comparing the device-tree before DTC translation without phandle and with phandle after translation.
