   1 * ST Microelectronics STMPE Multi-Functional Device
   2
   3 STMPE is an MFD device which may expose the following inbuilt devices: gpio,
   4 keypad, touchscreen, adc, pwm, rotator.
   5
   6 Required properties:
   7  - compatible                   : "st,stmpe[610|801|811|1600|1601|2401|2403]"
   8  - reg                          : I2C/SPI address of the device
   9
  10 Optional properties:
  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
  17
  18 Example:
  19
  20         stmpe1601: stmpe1601@40 {
  21                 compatible = "st,stmpe1601";
  22                 reg = <0x40>;
  23                 interrupts = <26 0x4>;
  24                 interrupt-parent = <&gpio6>;
  25                 interrupt-controller;
  26
  27                 wakeup-source;
  28                 st,autosleep-timeout = <1024>;
  29         };
