This series adds support for the Goodix Berlin-A series touch ICs (gt9897). This was tested on a Xiaomi 11 Lite 5G NE (xiaomi-lisa), which uses the gt9897 IC connected over SPI. I am not aware of any device that has gt9897 connected over I2C and therefore could not test it, so I didn't add a compatible in the I2C driver.
Changes in v4: - Fix the build for the i2c driver - Add Neil's R-b tag (patch no. 2) - Link to v3: https://lore.kernel.org/all/20250307094823.478152-1-adr...@mainlining.org/ Changes in v3: - Store the ic data in the goodix_berlin_core struct and pass it to goodix_berlin_probe from the i2c/spi probes (requested by Neil) - Resent from my now preferred e-mail for kernel work - Link to v2: https://lore.kernel.org/all/20250214052959.222668-1-adr...@travitia.xyz/ Changes in v2: - Added Rob's A-b tag (patch no. 1) - Added Luca's T-b tag (patch no. 2) - Updated the i2c and spi device id tables with the driver data and switched to spi_get_device_match_data where possible (requested by Neil) - Switched to device_get_match_data in goodix_berlin_core.c - Move all revision specific addresses and other properties into the goodix_berlin_ic_data struct (requested by Dmitry) - Link to v1: https://lore.kernel.org/all/20250203174309.21574-1-adr...@travitia.xyz/ To: Dmitry Torokhov <dmitry.torok...@gmail.com> To: Rob Herring <r...@kernel.org> To: Krzysztof Kozlowski <krzk...@kernel.org> To: Conor Dooley <conor...@kernel.org> To: Bastien Nocera <had...@hadess.net> To: Hans de Goede <hdego...@redhat.com> To: Neil Armstrong <neil.armstr...@linaro.org> Cc: Luca Weiss <luca.we...@fairphone.com> Cc: linux-in...@vger.kernel.org Cc: devicet...@vger.kernel.org Cc: linux-kernel@vger.kernel.org Cc: phone-de...@vger.kernel.org Cc: li...@mainlining.org Cc: ~postmarketos/upstream...@lists.sr.ht Signed-off-by: Jens Reidel <adr...@mainlining.org> Jens Reidel (2): dt-bindings: input: goodix,gt9916: Document gt9897 compatible Input: goodix_berlin - Add support for Berlin-A series .../input/touchscreen/goodix,gt9916.yaml | 1 + drivers/input/touchscreen/goodix_berlin.h | 16 ++++++- .../input/touchscreen/goodix_berlin_core.c | 21 ++++---- drivers/input/touchscreen/goodix_berlin_i2c.c | 14 ++++-- drivers/input/touchscreen/goodix_berlin_spi.c | 48 ++++++++++++++----- 5 files changed, 74 insertions(+), 26 deletions(-) -- 2.48.1
