From 7d24a43841a62bae825d0f0c2742f19fdf0ccb37 Mon Sep 17 00:00:00 2001 From: Jens Reidel Date: Fri, 14 Feb 2025 05:55:19 +0100 Subject: [PATCH v2 0/2] Add Goodix Berlin-A series support 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 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@travitia.xyz/ To: Dmitry Torokhov To: Rob Herring To: Krzysztof Kozlowski To: Conor Dooley To: Bastien Nocera To: Hans de Goede To: Neil Armstrong Cc: Luca Weiss Cc: linux-input@vger.kernel.org Cc: devicetree@vger.kernel.org Cc: linux-kernel@vger.kernel.org Cc: phone-devel@vger.kernel.org Cc: linux@mainlining.org Cc: ~postmarketos/upstreaming@lists.sr.ht Signed-off-by: Jens Reidel 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 | 13 ++++++ .../input/touchscreen/goodix_berlin_core.c | 15 ++++--- drivers/input/touchscreen/goodix_berlin_i2c.c | 9 +++- drivers/input/touchscreen/goodix_berlin_spi.c | 45 ++++++++++++++----- 5 files changed, 62 insertions(+), 21 deletions(-) -- 2.48.1
