1 * ST Microelectronics STMPE Multi-Functional Device
3 STMPE is an MFD device which may expose the following inbuilt devices: gpio,
4 keypad, touchscreen, adc, pwm, rotator.
7 - compatible : "st,stmpe[610|801|811|1601|2401|2403]"
8 - reg : I2C/SPI address of the device
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
