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.

Input: add core support for Goodix Berlin Touchscreen IC

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

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.

Input: add a new Novatek NVT-ts driver

2023-04-02T05:42:26+00:00

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

2023-02-01T16:23:38+00:00

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: add driver for Himax hx83112b touchscreen devices

2022-11-07T19:28:55+00:00

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

2022-11-01T14:57:33+00:00

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.
