| * QCEDEV (QTI Crypto Engine Device) |
| |
| Required properties: |
| - compatible : should be "qcom,qcedev" |
| - 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 "qcedev-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,msm_bus,vectors: Vectors for bus topology. |
| - qcom,ce-device: Device number. |
| - qcom,ce-opp-freq: indicates the CE operating frequency in Hz, changes from target to target. |
| |
| 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,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. |
