Subject: [PATCH RFC 0/4] input: touchscreen: add initial support for Goodix Berlin touchscreen IC
Date: Tue, 06 Jun 2023 16:31:55 +0200	[thread overview]
Message-ID: <20230606-topic-goodix-berlin-upstream-initial-v1-0-4a0741b8aefd@linaro.org> (raw)

These touchscreen ICs support SPI, I2C and I3C interface, up to
10 finger touch, stylus and gestures events.

This initial driver is derived from the Goodix goodix_ts_berlin
available at [1] and [2] and only supports the GT9916 IC
present on the Qualcomm SM8550 MTP & QRD touch panel.

The current implementation only supports BerlinD, aka GT9916.

Support for advanced features like:
- Firmware & config update
- Stylus events
- Gestures events
- Previous revisions support (BerlinA or BerlinB)
is not included in current version.

The current support will work with currently flashed firmware
and config, and bail out if firmware or config aren't flashed yet.
