+- command-reg: offset in memory for command register
+- status-reg: offset in memory for status register
+- data-reg: offset in memory for data register
+
+Optional properties:
+- init-reset: Controller should be reset on init and cleanup
+
+Optional Linux-specific properties:
+- linux,kbd_phys_desc: defaults to i8042/serio0
+- linux,aux_phys_desc: defaults to i8042/serio1
+- linux,mux_phys_desc: defaults to i8042/serio%d
+

+		compatible = "intel,8042";
+		reg = <0xd8008800 0x100>;
+		interrupts = <23 4>;
