Input: add driver for Hynitron CST816x series

2025-09-25T05:36:50+00:00

Introduce support for the Hynitron CST816x series touchscreen controller used for 240×240 1.28-inch Round LCD Display Module manufactured by Waveshare Electronics. The driver is designed based on an Arduino implementation marked as under MIT License. This driver is written for a particular round display based on the CST816S controller, which is not compatiable with existing driver for Hynitron controllers.

Input: add Himax HX852x(ES) touchscreen driver

2025-09-17T21:44:02+00:00

Add a simple driver for the Himax HX852x(ES) touch panel controller, with support for multi-touch and capacitive touch keys. The driver is somewhat based on sample code from Himax. However, that code was rather confusing, so that we spent a significant amount of time just trying to understand the packet format and register commands. In this driver they are described with clean structs and defines rather than magic numbers and offset calculations.

Input: apple_z2 - drop default ARCH_APPLE in Kconfig

2025-06-17T22:18:08+00:00

When the first driver for Apple Silicon was upstreamed we accidentally included `default ARCH_APPLE` in its Kconfig which then spread to almost every subsequent driver. As soon as ARCH_APPLE is set to y this will pull in many drivers as built-ins which is not what we want. Thus, drop `default ARCH_APPLE` from Kconfig.

Add a dependency on ARCH_APPLE and clarify the description to make it more obvious that this is for ARM machines, not x86 ones. Signed-off-by: Sasha Finkelstein Link: https://lore.kernel.org/r/20250225-z2-kconfig-v1-1-a67d9b778a6c@gmail.com Signed-off-by: Dmitry Torokhov

Input: cyttsp4 - remove driver

2024-08-05T17:48:49+00:00

The cyttsp4 touchscreen driver was contributed in 2013 and since then has seen no updates. The driver uses platform data (no device tree support) and there are no users of it in the mainline kernel. There were occasional fixes to it for issues either found by static code analysis tools or via visual inspection, but otherwise the driver is completely untested. Remove the driver.

Input: msc5000_ts - remove the driver

2024-07-16T01:12:23+00:00

MCS-5000 belongs to the 1st generation of Melfas chips, manufactured in 2000-2007. The driver relies on custom platform data (no DT support) and there never were any users of this driver in the mainline kernel. The commit adding the driver mentioned that the driver was tested on S3C6410 NCP board (with Samsung S3C6410 SoC) but the touchscreen device was never added to the board file. This board was removed in v6.3 in commit 743c8fbb90ca ("ARM: s3c: remove most s3c64xx board support"). Remove the driver since there are no users.

Input: goodix-berlin - add SPI support for Goodix Berlin Touchscreen IC

2024-01-30T23:16:32+00:00

Add initial support for the new Goodix "Berlin" touchscreen ICs over the SPI interface. The driver doesn't use the regmap_spi code since the SPI messages needs to be prefixed, thus this custom regmap code. 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.
