* QCRYPTO (QTI Crypto)

Required properties:
  - compatible : should be "qcom,qcrypto"
  - reg : should contain crypto, BAM register map.
  - reg-names : should contain the crypto and bam base register names.
  - interrupts : should contain crypto BAM interrupt.
  - qcom,bam-pipe-pair : should contain crypto BAM pipe pair index.
  - qcom,ce-hw-instance : should contain crypto HW instance.
  - qcom,msm_bus,name: Should be "qcrypto-noc"
  - qcom,msm_bus,num_cases: Depends on the use cases for bus scaling
  - qcom,msm_bus,active-only: Boolean flag for context of request (actve/dual)
  - qcom,msm_bus,num_paths: The paths for source and destination ports
  - qcom,ce-device: Device number. Device number is encoded with the following:
		bit 3-0   device type:	0 for full disk encryption(fde)
					1 for per file encrption(pfe)
		bit 7-4   unit number within the device type.


Optional properties:
  - qcom,ce-hw-shared : optional, indicates if the hardware is shared between EE.
  - qcom,ce-hw-key : optional, indicates if the hardware supports use of HW KEY.
  - qcom,use-sw-aes-cbc-ecb-ctr-algo : optional, indicates if use SW aes-cbc/ecb/ctr algorithm.
  - qcom,use-sw-aes-xts-algo : optional, indicates if use SW aes-xts algorithm.
  - qcom,use-sw-aead-algo : optional, indicates if use SW aead algorithm.
  - qcom,use-sw-ahash-algo : optional, indicates if use SW hash algorithm.
  - qcom,use-sw-hmac-algo : optional, indicates if use SW hmac algorithm.
  - qcom,use-sw-aes-ccm-algo : optional, indicates if use SW aes-ccm algorithm.
  - qcom,clk-mgmt-sus-res : optional, indicate if the ce clocks need to be disabled/enabled in suspend/resume function.
  - qcom,support-core-clk-only : optional, indicates if the HW supports single crypto core clk.
  - qcom,bsm-ee : optional, indicate the BAM EE value, changes from target to target.Default value is 1 if not specified.

  - qcom,ce-opp-freq: optional, indicates the CE operating frequency in Hz,
	changes from target to target. If not specified, by default the
	frequency is set as 100MHZ.

  - qcom,msm_bus,vectors: optional, indicates vectors for bus topology.
        This attribute is required for msm targets where bus scaling is
	required. For other targets such as fsm, they do not perform
	bus scaling. It is not required for those targets.
