This is not optional. It's perhaps inherited from the parent. You can 
drop it as it's implied by interrupts property.

+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.
+
+
+Optional properties:
+- interrupt-parent: Should be the phandle for the interrupt controller
+  that services interrupts for this device
+
+
+Example:
+   crypto: crypto@1b24 {
+   compatible = "mediatek,eip97-crypto";
+   reg = <0 0x1b24 0 0x2>;
+   interrupts = ,
+,
+,
+,
+;
+   clocks = <&topckgen CLK_TOP_ETHIF_SEL>,
+<ðsys CLK_ETHSYS_CRYPTO>;
+   clock-names = "ethif","cryp";
+   power-domains = <&scpsys MT2701_POWER_DOMAIN_ETH>;
