11 - compatible: Must be "microchip,qt1050"
12 - reg: The I2C address of the device
13 - interrupts: The sink for the touchpad's IRQ output,
14 see ../interrupt-controller/interrupts.txt
17 - wakeup-source: touch keys can be used as a wakeup source
19 Each button (key) is represented as a sub-node:
25 - linux,code: Keycode to emit.
26 - reg: The key number. Valid values: 0, 1, 2, 3, 4.
28 Optional subnode-properties:
33 - microchip,pre-charge-time-ns:
36 Valid value range: 0 - 637500; values must be a multiple of 2500;
38 - microchip,average-samples:
41 - microchip,average-scaling:
42 The scaling factor which is used to scale the average-samples.
44 - microchip,threshold:
46 Valid value range: 0 - 255; default is 20.
