+Azoteq IQS550/572/525 Trackpad/Touchscreen Controller
+
+Required properties:
+
+- compatible			: One of "azoteq,iqs550", "azoteq,iqs572" or
+				  "azoteq,iqs525".
+
+- reg				: I2C slave address for the device.
+
+- interrupts			: GPIO to which the device's RDY output is
+				  connected (see [0] for more information).
+
+- reset-gpios			: GPIO to which the device's NRST input is
+				  connected (see [1] for more information).
+				  Hardware reset access is required so as 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		: Minimum horizontal coordinate that can be
+				  reported by the device. If this property is
+				  omitted, zero is used.
+
+- touchscreen-min-y		: Minimum vertical coordinate that can be
+				  reported by the device. If this property is
+				  omitted, zero is used.
+
+- touchscreen-size-x		: Horizontal resolution (in pixels) of the touch
+				  area. If this property is omitted, the default
+				  horizontal resolution embedded in the device's
+				  firmware is used.
+
+- touchscreen-size-y		: Vertical resolution (in pixels) of the touch
+				  area. If this property is omitted, the default
+				  vertical resolution embedded in the device's
+				  firmware is used.
+
+- touchscreen-max-pressure	: Maximum touch strength that can be reported by
+				  the device, specified 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. The maximum touch strength is
+				  therefore dependent on hardware configuration
+				  and can vary by application.
+
+- touchscreen-fuzz-x		: Hysteresis level (in pixels) applied to the
+				  horizontal coordinates reported by the device.
+
+- touchscreen-fuzz-y		: Hysteresis level (in pixels) applied to the
+				  vertical coordinates reported by the device.
+
+- touchscreen-fuzz-pressure	: Hysteresis level applied to the strength level
+				  reported by the device, specified in the same
+				  units as touchscreen-max-pressure (deltas).
+
+- touchscreen-inverted-x	: Boolean to indicate that the horizontal axis
+				  of the touch area is inverted. Inversion is
+				  applied relative to that which may already be
+				  embedded in the device's firmware.
+
+- touchscreen-inverted-y	: Boolean to indicate that the vertical axis
+				  of the touch area is inverted. Inversion is
+				  applied relative to that which may already be
+				  embedded in the device's firmware.
+
+- touchscreen-swapped-x-y	: Boolean to indicate that the horizontal and
+				  vertical axes of the touch area are swapped.
+				  Transposition is applied relative to that
+				  which may already be embedded in the device's
+				  firmware.
