| * 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|1600|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>; | |
| }; |
