Hi Dmitry,

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

Thanks,
