| Required properties: |
| - compatible : Should be "qcom,qseecom" |
| - reg : should contain memory region address reserved for loading secure apps. |
| - qcom,disk-encrypt-pipe-pair : indicates what CE HW pipe pair is used for disk encryption |
| - qcom,file-encrypt-pipe-pair : indicates what CE HW pipe pair is used for file encryption |
| - qcom,hlos-ce-hw-instance : indicates what CE HW is used by HLOS crypto driver |
| - qcom,qsee-ce-hw-instance : indicates what CE HW is used by secure domain (TZ) crypto driver |
| - qcom, msm_bus,name: Should be "qseecom-noc" |
| - qcom, msm_bus,num_cases: Depends on the use cases for bus scaling |
| - qcom, msm_bus,num_paths: The paths for source and destination ports |
| - qcom, msm_bus,vectors: Vectors for bus topology. |
| |
| Optional properties: |
| - qcom,support-bus-scaling : indicates if driver support scaling the bus for crypto operation. |
| - qcom,support-fde : indicates if driver support key managing for full disk encryption feature. |
| - qcom,support-pfe : indicates if driver support key managing for per file encryption feature. |
| - qcom,no-clock-support : indicates clocks are not handled by qseecom (could be handled by RPM) |
| - qcom,appsbl-qseecom-support : indicates if there is qseecom support in appsbootloader |
