Input: apple_z2 - drop default ARCH_APPLE in Kconfig

2025-06-17T22:18:08Z

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.

Input: apple_z2 - fix potential confusion in Kconfig

2025-02-25T19:23:20Z

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

2024-08-05T17:48:49Z

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

2024-07-16T01:12:23Z

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

2024-01-30T23:16:32Z

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.

Input: add core support for Goodix Berlin Touchscreen IC

2024-01-30T23:16:32Z

Add initial support for the new Goodix "Berlin" touchscreen ICs. 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.
