+- reg : address and length of EMVSIM registers
+- interrupt : core interrupt controller
+- clocks : EMVSIM clock specifier
+- power-domains : power domain for EMVSIM
+
+Examples:
+
+emvsim0: sim0@5a0d0000 {
+       compatible = "fsl,imx8-emvsim";
+       reg = <0x0 0x5a0d0000 0x0 0x10000>;
+       interrupts = <GIC_SPI 230 IRQ_TYPE_LEVEL_HIGH>;

+       <&clk IMX8QM_EMVSIM0_IPG_CLK>;
+       clock-names = "sim", "ipg";
