This file is already present in the meantime (but applies with --3way).

DTC arch/arm/dts/bcm2835-rpi-zero-w.dtb
arch/arm/dts/bcm2835-rpi-zero-w.dtb: ERROR (phandle_references):
Reference to non-existent node or label "alt3"
ERROR: Input tree has errors, aborting (use -f to force output)
If I comment out alt3, it builds and boots okay. How to fix properly?

The v4.14 .dts file does not have this and does not seem to work. Does
this need to go into a -uboot.dtsi file instead or do more files need a
refresh?
