You'll have to forgive me; I'm submitting using some homemade tooling that is not yet stitched to get_maintainers, and I neglected to see that we're fortunate to have two more great maintainers.

Aren't they coming from common schema? Yes, but because additionalProperties is set to false here, we must explicitly include the subset of properties from the common schema that are allowed for this particular instance.

Why does this represent hardware property? This property and its cousin below define the physical boundaries of the touch surface. They are typically used to mask areas that cannot elicit an electrical response due to manufacturing tolerances or the presence of an overlay. For that reason, they descend directly from properties of the hardware. Similar properties already exist in this binding for the slider case; this device simply extends the functionality to a second dimenstion. > > > + > > + "^azoteq,upper-cal-(x|y)$": > > + $ref: /schemas/types.yaml#/definitions/uint32 > > + minimum: 0 > > + maximum: 255 > > + description: Specifies the trackpad's upper starting points. > > + > > + "^event-(press|tap|(swipe|flick)-(x|y)-(pos|neg))$": > > + type: object > > + $ref: input.yaml# > > + description: > > + Represents a press or gesture event reported by the trackpad.

Is it valid for IQS7222A? It's not, only for 'C' and now 'D'. However, the restriction for 'A' is already conveyed in an if/then schema in the original binding. So rather than updating this text to say "(IQS7222C and IQS7222D only)", I opted to drop the open-coded text and rely on the existing schema. > > > > Note that although multiple events can be mapped to a single > > GPIO, they must all be of the same type (proximity, touch or > > - slider gesture). > > + slider/trackpad gesture). > > > > azoteq,thresh: > > $ref: /schemas/types.yaml#/definitions/uint32 > > @@ -610,8 +757,8 @@ patternProperties: > > description: | > > Specifies one or more GPIO mapped to the event as follows: > > 0: GPIO0 > > - 1: GPIO3 (IQS7222C only) > > - 2: GPIO4 (IQS7222C only) > > + 1: GPIO3 > > + 2: GPIO4 > > > > Note that although multiple events can be mapped to a single > > GPIO, they must all be of the same type (proximity, touch or > > @@ -629,8 +776,8 @@ patternProperties: > > description: | > > Represents a GPIO mapped to one or more events as follows: > > gpio-0: GPIO0 > > - gpio-1: GPIO3 (IQS7222C only) > > - gpio-2: GPIO4 (IQS7222C only) > > + gpio-1: GPIO3 > > + gpio-2: GPIO4 > > > > allOf: > > - $ref: ../pinctrl/pincfg-node.yaml# > > @@ -641,6 +788,41 @@ patternProperties: > > additionalProperties: false > > > > allOf: > > + - $ref: touchscreen/touchscreen.yaml# > > + > > + - if: > > + properties: > > + compatible: > > + contains: > > + const: azoteq,iqs7222d > > + > > + then: > > + patternProperties: > > + "^cycle-[0-9]$": > > + properties: > > + azoteq,iref-enable: false > > + > > + "^channel-([0-9]|1[0-9])$": > > + properties: > > + azoteq,ref-select: false > > + > > + "^slider-[0-1]$": false > > + > > + else: > > + properties: > > + touchscreen-size-x: false > > + touchscreen-size-y: false > > + touchscreen-inverted-x: false > > + touchscreen-inverted-y: false > > + touchscreen-swapped-x-y: false > > + > > + trackpad: false > > The binding got quite complicated. Are you sure these are similar devices? Yes, I'm quite sure. The silicon is largely the same, the primary difference being the way two access are reported (2x 1-D vs. 1x 2-D). The binding hasn't necessarily grown functionally; rather, most properties from the slider-0/1 node are simply re-used or extended to two dimensions for the new trackpad node. My long-term goal is to defer most of these properties to a common vendor schema as per my note to Rob in [1], but it does not seem possible yet. If I'm mistaken, or there is a more efficient means of re-use under the current tooling, I'll happily follow suit.
