Subject: [PATCH 9/9] dt-bindings: input: iqs5xx: Convert to YAML
Date: Thu, 4 Mar 2021 22:12:36 -0600 [thread overview]
Message-ID: <20210305041236.3489-10-jeff@labundy.com> (raw)
In-Reply-To: <20210305041236.3489-1-jeff@labundy.com>
This patch converts the legacy text-based binding document to YAML
format. Extraneous details and touchscreen properties that weren't
actually supported have been dropped.
The reset GPIO has since been made optional in the driver; this is
now reflected here as well.

-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
- 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 field.
