Is this the real product name? When I rewrote the bindings for
the original "CYTTSP", actually "Cypress TrueTouch Standard Product"
it came out that the actual product names were CY8CTMA340
and CY8CTMA341. "CYTTSP" was a marketing name for the
whole family.

See
Documentation/devicetree/bindings/input/touchscreen/cypress,cy8ctma340.yaml

If the actual products have some product names such as
CY8* then use these as compatibles instead and just write in the
decription that it is Cypress TrueTouch Standard Product series 5.

Yours,
Linus Walleij
