[PATCH v7 1/7] dt-bindings: input: syna,rmi4: Document syna,rmi4-s3706b

[David Heidelberg via B4 Relay]

From: David Heidelberg <david@xxxxxxx>

Mostly irrelevant for authentic Synaptics touchscreens, but very important
for applying workarounds to cheap TS knockoffs.

These knockoffs work well with the downstream driver, and since the user
has no way to distinguish them, later in this patch set, we introduce
workarounds to ensure they function as well as possible.

Acked-by: Krzysztof Kozlowski <krzysztof.kozlowski@xxxxxxxxxx>
