The PineCube board has a RTL8189ES Wi-Fi module on board, and the module

Add a ethernet alias in the DT, thus the bootloader will then be able to

The address and size cells infomation in CSI subnode is not necessary
(because the camera subnode has no reg property).
Drop them.

This patchset tries to fix DT schema verification errors that exist in
V3-series device trees.
The first patch drops bogus properties that is not needed in PineCube
DT, and the second one adds compatible to the binding.
