* ST Microelectronics STMPE Multi-Functional Device
STMPE is an MFD device which may expose the following inbuilt devices: gpio,
keypad, touchscreen, adc, pwm, rotator.
Required properties:
- compatible : "st,stmpe[610|801|811|1601|2401|2403]"
- reg : I2C/SPI 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
- wakeup-source : Marks the input device as wakable
- st,autosleep-timeout : Valid entries (ms); 4, 16, 32, 64, 128, 256, 512 and 1024
- irq-gpio : If present, which GPIO to use for event IRQ
Example:
stmpe1601: stmpe1601@40 {
compatible = "st,stmpe1601";
reg = <0x40>;
interrupts = <26 0x4>;
interrupt-parent = <&gpio6>;
interrupt-controller;
wakeup-source;
st,autosleep-timeout = <1024>;
};
