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 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 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-adrian@xxxxxxxxxxxx/ To: Dmitry Torokhov <dmitry.torokhov@xxxxxxxxx> To: Rob Herring <robh@xxxxxxxxxx> To: Krzysztof Kozlowski <krzk+dt@xxxxxxxxxx> To: Conor Dooley <conor+dt@xxxxxxxxxx> To: Bastien Nocera <hadess@xxxxxxxxxx> To: Hans de Goede <hdegoede@xxxxxxxxxx> To: Neil Armstrong <neil.armstrong@xxxxxxxxxx> Cc: Luca Weiss <luca.weiss@xxxxxxxxxxxxx> Cc: linux-input@xxxxxxxxxxxxxxx Cc: devicetree@xxxxxxxxxxxxxxx Cc: linux-kernel@xxxxxxxxxxxxxxx Cc: phone-devel@xxxxxxxxxxxxxxx Cc: linux@xxxxxxxxxxxxxx Cc: ~postmarketos/upstreaming@xxxxxxxxxxx Signed-off-by: Jens Reidel <adrian@xxxxxxxxxxxxxx> 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
