1	* ST Microelectronics STMPE Multi-Functional Device
2	
3	STMPE is an MFD device which may expose the following inbuilt devices: gpio,
4	keypad, touchscreen, adc, pwm, rotator.
5	
6	Required properties:
7	 - compatible                   : "st,stmpe[610|801|811|1601|2401|2403]"
8	 - reg                          : I2C/SPI address of the device
9	
10	Optional properties:
11	 - interrupts                   : The interrupt outputs from the controller
12	 - interrupt-controller         : Marks the device node as an interrupt controller
13	 - interrupt-parent             : Specifies which IRQ controller we're connected to
14	 - wakeup-source                : Marks the input device as wakable
15	 - st,autosleep-timeout         : Valid entries (ms); 4, 16, 32, 64, 128, 256, 512 and 1024
16	 - irq-gpio                     : If present, which GPIO to use for event IRQ
17	
18	Example:
19	
20		stmpe1601: stmpe1601@40 {
21			compatible = "st,stmpe1601";
22			reg = <0x40>;
23			interrupts = <26 0x4>;
24			interrupt-parent = <&gpio6>;
25			interrupt-controller;
26	
27			wakeup-source;
28			st,autosleep-timeout = <1024>;
29		};
