Subject: [PATCH v2 0/2] input: touchscreen: goodix_berlin: Add stylus support

This series introduces a new input device dedicated to stylus reporting,
allowing handling of stylus-specific data such as pressure, tilt, and
side buttons. The implementation distinguishes between touch and stylus
events and ensures that the appropriate input device reports each event.
