* 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";

}
