Qualcomm crypto engine driver
Required properties:
- compatible : should be "qcom,crypto-v5.1"
- reg : specifies base physical address and size of the registers map
- clocks : phandle to clock-controller plus clock-specifier pair
- clock-names : "iface" clocks register interface
"bus" clocks data transfer interface
"core" clocks rest of the crypto block
- dmas : DMA specifiers for tx and rx dma channels. For more see
Documentation/devicetree/bindings/dma/dma.txt
- dma-names : DMA request names should be "rx" and "tx"
Example:
crypto@fd45a000 {
compatible = "qcom,crypto-v5.1";
reg = <0xfd45a000 0x6000>;
clocks = <&gcc GCC_CE2_AHB_CLK>,
<&gcc GCC_CE2_AXI_CLK>,
<&gcc GCC_CE2_CLK>;
clock-names = "iface", "bus", "core";
dmas = <&cryptobam 2>, <&cryptobam 3>;
dma-names = "rx", "tx";
};
