| * 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,request-bw-before-clk : optional, indicates if the HW supports bandwidth requests prior to clock controls. |
| - 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. |
