+* ARC PS/2 driver: PS/2 block used in some ARC FPGA's & nSIM OSCI model
+
+Required properties:
+- compatible            : "snps,arc_ps2"
+- reg                   : offset and length (always 0x14) of registers
+- interrupts            : interrupt
+- interrupt-names       : name of interrupt, must be "arc_ps2_irq"
+
+Example:
+
+serio@c9000400 {
+        compatible = "snps,arc_ps2";
+        reg = <0xc9000400 0x14>;
+        interrupts = <13>;
+        interrupt-names = "arc_ps2_irq";
+}
