[PATCH 1/5] dt-bindings: input: touchscreen: imagis: add compatible for IST4050

From: Markuss Broks via B4 Relay

Date: Fri Aug 21 2026 - 17:33:00 EST


From: Markuss Broks <markuss.broks@xxxxxxxxx>

The IST4050 is a touchscreen IC of the Imagis IST40xx family. It shares
the register interface with IST3038C, but uses a different, event-based
touch reporting format and does not have touch keys.

The binding no longer covers only the IST30XXC family, so generalize its
title as well.
