Input: edt-ft5x06 - select REGMAP_I2C

2023-04-10T23:56:47Z

After starting to use regmap API to access registers the edt-ft5x06 driver depends on symbols provided by REGMAP_I2C: edt-ft5x06.o: in function `edt_ft5x06_ts_probe': edt-ft5x06.c:1154: undefined reference to `__regmap_init_i2c' edt-ft5x06.o: in function `edt_ft5x06_ts_identify': edt-ft5x06.c:897: undefined reference to `__regmap_init_i2c' Make sure support for I2C regmap is actually selected by adding this dependency to Kconfig.

Input: add a new Novatek NVT-ts driver

2023-04-02T05:42:26Z

Add a new driver for the Novatek i2c touchscreen controller as found on the Acer Iconia One 7 B1-750 tablet. Unfortunately the touchscreen controller model-number is unknown. Even with the tablet opened up it is impossible to read the model-number. Android calls this a "NVT-ts" touchscreen, but that may apply to other Novatek controller models too. This appears to be the same controller as the one supported by https://github.com/advx9600/android/blob/master/touchscreen/NVTtouch_Android4.0/NVTtouch.c but unfortunately that does not give us a model-number either.

mfd: remove ucb1400 support

2023-02-01T16:23:38Z

The ucb1400 MFD driver and its gpio and touchscreen child drivers were only used on a few PXA machines that were unused for a while and are now removed. Removing these leaves the AC97 support as ALSA specific, no other drivers are now connected through this interface.

Input: stmpe-ts - drop obsolete dependency on COMPILE_TEST

2022-11-22T22:20:28Z

Since commit 0166dc11be91 ("of: make CONFIG_OF user selectable"), it is possible to test-build any driver which depends on OF on any architecture by explicitly selecting OF. Therefore depending on COMPILE_TEST as an alternative is no longer needed. It is actually better to always build such drivers with OF enabled, so that the test builds are closer to how each driver will actually be built on its intended target. Building them without OF may not test much as the compiler will optimize out potentially large parts of the code. In the worst case, this could even pop false positive warnings. Dropping COMPILE_TEST here improves the quality of our testing and avoids wasting time on non-existent issues.

Input: add driver for Himax hx83112b touchscreen devices

2022-11-07T19:28:55Z

This patch adds support for Himax hx83112b touchscreen devices. As there are no publicly available data sheets for these devices, the implementation is based on the driver of the downstream Android kernel used in the Fairphone 3. This patch is a complete rewrite, though, and the code bears no resemblence to the original implementation. The driver has been tested on the aforementioned phone.

Input: Add driver for Cypress Generation 5 touchscreen

2022-11-01T14:57:33Z

This is the basic driver for the Cypress TrueTouch Gen5 touchscreen controllers. This driver supports only the I2C bus but it uses regmap so SPI support could be added later. The touchscreen can retrieve some defined zone that are handled as buttons (according to the hardware). That is why it handles button and multitouch events.

Input: add driver for Hynitron cstxxx touchscreens

2022-10-30T04:34:16Z

Add support for the Hynitron cst3xx controller found on devices such as the Anbernic RG353P and RG353V (the Hynitron CST340). This driver was built from sources provided by Hynitron to Anbernic (possibly via Rockchip as an intermediary) and marked as GPLv2 in the code. This driver was written strictly for the cst3xx series, but in most places was left somewhat generic so support could be easily added to other devices in the future.
