title: Qualcomm SoC compatibles naming convention

  Guidelines for new compatibles for SoC blocks/components.
  When adding new compatibles in new bindings, use the format::
    qcom,SoC-IP

  For example::
   qcom,sdm845-llcc-bwmon

  When adding new compatibles to existing bindings, use the format in the
  existing binding, even if it contradicts the above.
