Aeroflex Gaisler APBPS2 PS/2 Core, supporting Keyboard or Mouse.



The APBPS2 PS/2 core is available in the GRLIB VHDL IP core library.



Note: In the ordinary environment for the APBPS2 core, a LEON SPARC system,

these properties are built from information in the AMBA plug&play and from

bootloader settings.



Required properties:



- name : Should be "GAISLER_APBPS2" or "01_060"

- reg : Address and length of the register set for the device

- interrupts : Interrupt numbers for this device



For further information look in the documentation for the GLIB IP core library:

* AUO in-cell touchscreen controller using Pixcir sensors



Required properties:

- compatible: must be "auo,auo_pixcir_ts"

- reg: I2C address of the chip

- interrupts: interrupt to which the chip is connected

- gpios: gpios the chip is connected to

  first one is the interrupt gpio and second one the reset gpio

- x-size: horizontal resolution of touchscreen

- y-size: vertical resolution of touchscreen



Example:



	i2c@00000000 {

		/* ... */



		auo_pixcir_ts@5c {

			compatible = "auo,auo_pixcir_ts";

			reg = <0x5c>;

			interrupts = <2 0>;



			gpios = <&gpf 2 0 2>, /* INT */

				<&gpf 5 1 0>; /* RST */



			x-size = <800>;

			y-size = <600>;

		};



		/* ... */

* Sitronix st1232 touchscreen controller



Required properties:

- compatible: must be "sitronix,st1232"

- reg: I2C address of the chip

- interrupts: interrupt to which the chip is connected



Optional properties:

- gpios: a phandle to the reset GPIO



Example:



	i2c@00000000 {

		/* ... */



		touchscreen@55 {

			compatible = "sitronix,st1232";

			reg = <0x55>;

			interrupts = <2 0>;

			gpios = <&gpio1 166 0>;

* 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";
