Qualcomm crypto engine driver

Required properties:
4
5
- compatible : should be "qcom,crypto-v5.1"
6
- reg : specifies base physical address and size of the registers map
7
- clocks : phandle to clock-controller plus clock-specifier pair
8
- clock-names : "iface" clocks register interface
9
"bus" clocks data transfer interface
10
"core" clocks rest of the crypto block
11
- dmas : DMA specifiers for tx and rx dma channels. For more see
12
Documentation/devicetree/bindings/dma/dma.txt
13
- dma-names : DMA request names should be "rx" and "tx"

Example:
16
crypto@fd45a000 {
17
compatible = "qcom,crypto-v5.1";
18
reg = <0xfd45a000 0x6000>;
19
clocks = <&gcc GCC_CE2_AHB_CLK>,
20
<&gcc GCC_CE2_AXI_CLK>,
21
<&gcc GCC_CE2_CLK>;
22
clock-names = "iface", "bus", "core";
23
dmas = <&cryptobam 2>, <&cryptobam 3>;
24
dma-names = "rx", "tx";
