Subject: Aw: [PATCH v2 4/5] arm64: dts: mt7986: add dtbs with applied
 overlays for bpi-r3

Hi

Parts 1-3 are applied here, but how to proceed with this? to add further devicetrees like
for mt7988 we have to fix the "broken" dt-overlays first.

i want to keep to build the dtbo to allow dynamic apply in bootloader, but they should be checked in
compiletime too and full dtb should be created for users not wanting to handle overlays.

regards Frank
