MediaTek cryptographic accelerators
Required properties:
- compatible: Should be "mediatek,eip97-crypto"
- reg: Address and length of the register set for the device
- interrupts: Should contain the five crypto engines interrupts in numeric
order. These are global system and four descriptor rings.
- clocks: the clock used by the core
- clock-names: the names of the clock listed in the clocks property. These are
"ethif", "cryp"
- power-domains: Must contain a reference to the PM domain.
Example:
crypto: crypto@1b240000 {
compatible = "mediatek,eip97-crypto";
reg = <0 0x1b240000 0 0x20000>;
interrupts = <GIC_SPI 82 IRQ_TYPE_LEVEL_LOW>,
<GIC_SPI 83 IRQ_TYPE_LEVEL_LOW>,
<GIC_SPI 84 IRQ_TYPE_LEVEL_LOW>,
<GIC_SPI 91 IRQ_TYPE_LEVEL_LOW>,
<GIC_SPI 97 IRQ_TYPE_LEVEL_LOW>;
clocks = <&topckgen CLK_TOP_ETHIF_SEL>,
<&ethsys CLK_ETHSYS_CRYPTO>;
clock-names = "ethif","cryp";
power-domains = <&scpsys MT2701_POWER_DOMAIN_ETH>;
};
