| KLM - Key Ladder Module |
| |
| KLM is a HW module which generates and decrypt keys in a secured manner. |
| The KLM transfers generated keys securely into TSPP2 Key Table. |
| |
| The devicetree representation of the KLM block should be: |
| |
| Required properties: |
| |
| - compatible: "qcom,klm" |
| - reg: physical memory base addresses and sizes for the following: |
| KLM, TSPP2, BCSS_HLOS, BCSS_KLM. |
| - reg-names: names of the memory regions: |
| MSM_KLM, MSM_BCSS_TSPP2, MSM_BCSS_HLOS, MSM_BCSS_KLM |
| - vdd-supply: power regulator (GDSC) supplying power to the broadcast subsystem. |
| |
| Example: |
| |
| klm: msm-klm@fc560000 { |
| compatible = "qcom,klm"; |
| reg = <0xfc560000 0x1000>, /* KLM registers */ |
| <0xfc724000 0x7000>, /* TSPP2 registers */ |
| <0xfc747000 0x1000>, /* KLM debug mode */ |
| <0xfc748200 0x100>; /* Key Tables */ |
| reg-names = "MSM_KLM", "MSM_BCSS_TSPP2", "MSM_BCSS_HLOS", "MSM_BCSS_KLM"; |
| vdd-supply = <&gdsc_bcss>; |
| }; |
