  dt-bindings: remoteproc: qcom: adsp: Add compatible name for SC7280
  remoteproc: qcom: Add compatible name for SC7280 ADSP
  remoteproc: qcom: Update hard coded values with macros
  remoteproc: qcom: Add efuse evb selection control
  remoteproc: qcom: Add flag in adsp private data structure
  remoteproc: qcom: Add support for memory sandbox
