4Required properties:
5 - compatible: "st,stmpe-gpio"

7Optional properties:
8 - st,norequest-mask: bitmask specifying which GPIOs should _not_ be requestable
9 due to different usage (e.g. touch, keypad)

14Example:
15 stmpe_gpio {
16 compatible = "st,stmpe-gpio";
17 st,norequest-mask = <0x20>; //gpio 5 can't be used
