Kernel-4.18.0-80.el8_stmpe

• 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>;
};
