This AES Engine is available in the Mediatek MT76x8 SoC.

It enables hardware crypto for AES-ECB and AES-CBC with 128/192/256 keysize.

This should be added to your device DTS or better yet to the mt76x8.dtsi:

crypto: crypto@10004000 {
	compatible = "mediatek,mtk-aes";
	reg = <0x10004000 0x1000>;

	interrupt-parent = <&intc>;
	interrupts = <13>;

	resets = <&rstctrl 29>;
	reset-names = "cryp";
	clocks = <&clkctrl 29>;
	clock-names = "cryp";
};

Benchmark: By default crypto-blocks <100 bytes are software only

You have chosen to measure elapsed time instead of user CPU time.
