1* ST Microelectronics STMPE Multi-Functional Device
2
3STMPE is an MFD device which may expose the following inbuilt devices: gpio,
4keypad, touchscreen, adc, pwm, rotator.

6Required properties:
7 - compatible                   : "st,stmpe[610|801|811|1601|2401|2403]"
8 - reg                          : I2C/SPI address of the device
9
10Optional 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

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	};
