Wit this series applied I see build failures like:

arch/arm64/boot/dts/ti/k3-am65-main.dtsi:897.25-916.4: Warning (unique_unit_address): /bus at 100000/pcie at 5600000: duplicate unit-address (also used in node /bus at 100000/pcie-ep at 5600000)

  DTOVL   arch/arm64/boot/dts/ti/k3-am654-base-board.dtb

Overlay 'arch/arm64/boot/dts/ti/k3-am654.dtsi' is incomplete (4096 / 1346656301 bytes read)
make[3]: *** [scripts/Makefile.lib:402: arch/arm64/boot/dts/ti/k3-am654-base-board.dtb] Error 1

make[1]: *** [/home/a0132425/workspace/k3-next/Makefile:1391: dtbs] Error 2
make: *** [Makefile:234: __sub-make] Error 2

There probably is some race here as I see this with make -j32 dtbs 
but not on my less powerful laptop
