1STMPE gpio 2---------- 3 4Required properties: 5 - compatible: "st,stmpe-gpio" 6 7Optional properties: 8 - st,norequest-mask: bitmask specifying which GPIOs should _not_ be requestable 9 due to different usage (e.g. touch, keypad) 10 11Node should be child node of stmpe node to which it belongs. 12 13Example: 14 stmpe_gpio { 15 compatible = "st,stmpe-gpio"; 16 st,norequest-mask = <0x20>; //gpio 5 can't be used 17 }; 18
