+Intel 8042 Keyboard Controller
+
+Required properties:
+- compatible: should be "intel,8042"
+- regs: memory for keyboard controller
+- interrupts: usually, two interrupts should be specified (keyboard and aux).
+ However, only one interrupt is also allowed in case of absence of the
+ physical port in the controller. The i8042 driver must be loaded with
+ nokbd/noaux option in this case.
+- interrupt-names: interrupt names corresponding to numbers in the list.
+ "kbd" is the keyboard interrupt and "aux" is the auxiliary (mouse)
+ interrupt.
+- command-reg: offset in memory for command register
+- status-reg: offset in memory for status register
+- data-reg: offset in memory for data register
+
+Example:
+ i8042@d8008800 {
+ compatible = "intel,8042";
+ regs = <0xd8008800 0x100>;
+ interrupts = <23>, <4>;
+ interrupt-names = "kbd", "aux";
+ command-reg = <0x04>;
+ status-reg = <0x04>;
+ data-reg = <0x00>;
+ };
