   2
   3STMPE is an MFD device which may expose the following inbuilt devices: gpio,
   4keypad, touchscreen, adc, pwm, rotator.
   5
   6Required properties:
   7 - compatible                   : "st,stmpe[610|801|811|1601|2401|2403]"
   8 - reg                          : I2C/SPI address of the device
   9
  10Optional 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

  17Example:
  18
  19        stmpe1601: stmpe1601@40 {
  20                compatible = "st,stmpe1601";
  21                reg = <0x40>;
  22                interrupts = <26 0x4>;
  23                interrupt-parent = <&gpio6>;
  24                interrupt-controller;
  25
  26                wakeup-source;
  27                st,autosleep-timeout = <1024>;
  28        };
