Microchip AT42QT1050 Five-channel Touch Sensor IC
The AT42QT1050 (QT1050) is a QTouchADC sensor device. The device can sense from
one to five keys, dependent on mode. The QT1050 includes all signal processing
functions necessary to provide stable sensing under a wide variety of changing
conditions, and the outputs are fully debounced.
The touchkey device node should be placed inside an I2C bus node.
Required properties:
- compatible: Must be "microchip,qt1050"
- reg: The I2C address of the device
- interrupts: The sink for the touchpad's IRQ output,
see ../interrupt-controller/interrupts.txt
Optional properties:
- wakeup-source: touch keys can be used as a wakeup source
Each button (key) is represented as a sub-node:
Each not specified key or key with linux,code set to KEY_RESERVED gets disabled
in HW.
Subnode properties:
- linux,code: Keycode to emit.
- reg: The key number. Valid values: 0, 1, 2, 3, 4.
Optional subnode-properties:
If a optional property is missing or has a invalid value the default value is
taken.
- microchip,pre-charge-time-ns:
Each touchpad need some time to precharge. The value depends on the mechanical
layout.
Valid value range: 0 - 637500; values must be a multiple of 2500;
default is 0.
- microchip,average-samples:
Number of data samples which are averaged for each read.
Valid values: 1, 4, 16, 64, 256, 1024, 4096, 16384; default is 1.
- microchip,average-scaling:
The scaling factor which is used to scale the average-samples.
Valid values: 1, 2, 4, 8, 16, 32, 64, 128; default is 1.
- microchip,threshold:
Number of counts to register a touch detection.
Valid value range: 0 - 255; default is 20.
Example:
QT1050 with 3 non continuous keys, key2 and key4 are disabled.

Azoteq IQS550/572/525 Trackpad/Touchscreen Controller
Required properties:
- compatible : Must be equal to one of the following:
"azoteq,iqs550"
"azoteq,iqs572"
"azoteq,iqs525"
- reg : I2C slave address for the device.
- interrupts : GPIO to which the device's active-high RDY
output is connected (see [0]).
- reset-gpios : GPIO to which the device's active-low NRST
input is connected (see [1]).
Optional properties:
- touchscreen-min-x : See [2].
- touchscreen-min-y : See [2].
- touchscreen-size-x : See [2]. If this property is omitted, the
maximum x-coordinate is specified by the
device's "X Resolution" register.
- touchscreen-size-y : See [2]. If this property is omitted, the
maximum y-coordinate is specified by the
device's "Y Resolution" register.
- touchscreen-max-pressure : See [2]. Pressure is expressed as the sum of
the deltas across all channels impacted by a
touch event. A channel's delta is calculated
as its count value minus a reference, where
the count value is inversely proportional to
the channel's capacitance.
- touchscreen-fuzz-x : See [2].
- touchscreen-fuzz-y : See [2].
- touchscreen-fuzz-pressure : See [2].
- touchscreen-inverted-x : See [2]. Inversion is applied relative to that

FLIP_X and FLIP_Y register fields.
- touchscreen-inverted-y : See [2]. Inversion is applied relative to that
which may already be specified by the device's
FLIP_X and FLIP_Y register fields.
