STMPE gpio

Required properties:

  • compatible: “st,stmpe-gpio”

Optional properties:

  • st,norequest-mask: bitmask specifying which GPIOs should not be requestable
    due to different usage (e.g. touch, keypad)

Node name must be stmpe_gpio and should be child node of stmpe node to which it
belongs.

Example:
stmpe_gpio {
compatible = “st,stmpe-gpio”;
st,norequest-mask = <0x20>; //gpio 5 can’t be used
};
