		* QSEECOM (QTI Secure Execution Environment Communicator)

		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,support-multiple-ce-hw-instance : indicates if multicore CE support is supported.
		- qcom,hlos-num-ce-hw-instances : indicates number of CE HW instances hlos can use.
		- 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.
		- qcom,ce-opp-freq: indicates the CE operating frequency in Hz, changes from target to target.
		- qcom,full-disk-encrypt-info : Vectors defining full disk encryption unit, crypto engine, pipe pair configuration in <unit#, ce#, pipe-pair#>
		- qcom,per-file-encrypt-info : Vectors defining per file encryption unit, crypto engine, pipe pair configuration in <unit#, ce#, pipe-pair#>

		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
		- vdd-hba-supply : handle for fixed power regulator
		- qcom,qsee-reentrancy-support: indicates the qsee reentrancy phase supported by the target
		- qcom,commonlib64-loaded-by-uefi: indicates commonlib64 is loaded by uefi already
		- qcom,fde-key-size: indicates which FDE key size is used in device.

		Example:
		qcom,qseecom@fe806000 {
		compatible = "qcom,qseecom";
		reg = <0x7f00000 0x500000>;
