On X Elite, there is a crypto engine IP block similar to ones found on SM8x50 platforms. Describe the crypto engine and its BAM. Signed-off-by: Abel Vesa <abel.vesa@xxxxxxxxxx> --- The dt-binding schema update for the x1e80100 compatible is here (already picked up): https://lore.kernel.org/all/20250213-dt-bindings-qcom-qce-x1e80100-v1-1-d17ef73a1c12@xxxxxxxxxx/ --- Changes in v2: - Added EE and channels numbers in BAM node, like Stephan suggested. - Added v1.7.4 compatible as well. - Link to v1: https://lore.kernel.org/r/20250213-x1e80100-crypto-v1-1-f93afdd4025a@xxxxxxxxxx --- arch/arm64/boot/dts/qcom/x1e80100.dtsi | 32 ++++++++++++++++++++++++++++++++ 1 file changed, 32 insertions(+) diff --git a/arch/arm64/boot/dts/qcom/x1e80100.dtsi b/arch/arm64/boot/dts/qcom/x1e80100.dtsi index 9d38436763432892ceef95daf0335d4cf446357c..71d5f5eed4511030a51fb12e453f603d294080cc 100644 --- a/arch/arm64/boot/dts/qcom/x1e80100.dtsi +++ b/arch/arm64/boot/dts/qcom/x1e80100.dtsi @@ -3708,6 +3708,38 @@ pcie4_phy: phy@1c0e000 { status = "disabled"; }; + cryptobam: dma-controller@1dc4000 { + compatible = "qcom,bam-v1.7.4", "qcom,bam-v1.7.0"; + reg = <0 0x01dc4000 0 0x28000>; + + interrupts = <GIC_SPI 272 IRQ_TYPE_LEVEL_HIGH>; + + #dma-cells = <1>; + + iommus = <&apps_smmu 0x480 0>, + <&apps_smmu 0x481 0>; + + qcom,ee = <0>; + qcom,num-ees = <7>; + num-channels = <30>; + qcom,controlled-remotely; + }; + + crypto: crypto@1dfa000 { + compatible = "qcom,x1e80100-qce", "qcom,sm8150-qce", "qcom,qce"; + reg = <0 0x01dfa000 0 0x6000>; + + interconnects = <&aggre2_noc MASTER_CRYPTO QCOM_ICC_TAG_ALWAYS + &mc_virt SLAVE_EBI1 QCOM_ICC_TAG_ALWAYS>; + interconnect-names = "memory"; + + dmas = <&cryptobam 4>, <&cryptobam 5>; + dma-names = "rx", "tx"; + + iommus = <&apps_smmu 0x480 0>, + <&apps_smmu 0x481 0>; + }; + tcsr_mutex: hwlock@1f40000 { compatible = "qcom,tcsr-mutex"; reg = <0 0x01f40000 0 0x20000>; --- base-commit: d4b0fd87ff0d4338b259dc79b2b3c6f7e70e8afa change-id: 20250213-x1e80100-crypto-18c7d14cd459 Best regards, -- Abel Vesa <abel.vesa@xxxxxxxxxx>
