* STMPE Multi-Functional Device



Required properties:

 - compatible                   : "st,stmpe[811|1601|2401|2403]"

 - reg                          : I2C address of the device



Optional properties:

 - interrupts                   : The interrupt outputs from the controller

 - interrupt-controller         : Marks the device node as an interrupt controller

 - interrupt-parent             : Specifies which IRQ controller we're connected to

 - i2c-client-wake              : Marks the input device as wakable

 - st,autosleep-timeout         : Valid entries (ms); 4, 16, 32, 64, 128, 256, 512 and 1024



Example:



	stmpe1601: stmpe1601@40 {

		compatible = "st,stmpe1601";

		reg = <0x40>;

		interrupts = <26 0x4>;

		interrupt-parent = <&gpio6>;

		interrupt-controller;



		i2c-client-wake;

		st,autosleep-timeout = <1024>;

	};
