-* 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
-
-Example:
-
- stmpe1601: stmpe1601@40 {
- compatible = "st,stmpe1601";
- reg = <0x40>;
- interrupts = <26 0x4>;
- interrupt-parent = <&gpio6>;
- interrupt-controller;
-
- wakeup-source;
- st,autosleep-timeout = <1024>;
- };
