| * 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>; |
| }; |
