+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]). Hardware reset
+				  access is required in order to to facilitate
+				  in-system firmware replacement.
+
+Optional properties:
+
+- azoteq,exp-ver-major		: Major field of the export file version number
+				  (0 through 255 inclusive). This property must
+				  be specified as a '/bits/ 8' value.
+
+- azoteq,exp-ver-minor		: Minor field of the export file version number
+				  (0 through 255 inclusive). This property must
+				  be specified as a '/bits/ 8' value.
+
+				  The export file version number is a customer-
+				  assigned parameter embedded in the device's
+				  firmware at the time it is exported from the
+				  manufacturer's PC-based configuration tool.
+
+				  If the export file version number stored in
+				  the device's nonvolatile memory does not match
+				  the number specified here, the driver replaces
+				  the firmware on the device with that which is
+				  stored on the local filesystem (for which the
+				  export file version number must match).
+
+				  If both major and minor fields are omitted or
+				  specified as zero, the driver does not query
+				  the device's export file version number.
+
+- 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
+				  which may already be specified by the device's
+				  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.
+
+- touchscreen-swapped-x-y	: See [2]. Swapping is applied relative to that
+				  which may already be specified by the device's
+				  SWITCH_XY_AXIS register fields.
