Thanks! Yes. All the DTS changes are merged in the Linux and are available at arch/arm64/boot/dts/broadcom/stingray/ Best regards, Rayagonda > > -- > Tom

Please reference the release you're taking these from as that will make future resyncs easier. Thanks!

Will the renaming complicate synchronization? Do we need to maintain the same dt file between linux and uboot ? Also in uboot we don't enable all devices, how do we handle this ? Please let me know.

If there is no U-Boot driver for a particular node then it will be ignored. It is easier to keep them in sync if they are the same in U-Boot and Linux. > Please let me know. That is implied by your question above :-) Regards, SImon
