Hi Dmitry,

For Qualcomm DTBs extending the compatible string would be sufficient as th=
e format planned is=20
compatible =3D "qcom,<SoC>[-<soc_version>][-<foundry_id>]-<board>[/<subtype=
>][-<pmic>][-<board_version>]"
=20
In this "qcom,<SoC>" would be from base Kernel device tree and remaining pa=
rt to be added via extension.=20
If others also agree to replace the entire compatible sting, then entire st=
ring can be updated in the format we like.=20
Either case the Qualcomm DTB fitImages have a path forward.=20

Thanks,
Kavinaya
