Input: add zinitix touchscreen driver

2020-10-04T23:08:09+00:00

Add support for the bt541 touchscreen IC from zinitix, loosely based on
downstream driver. The driver currently supports multitouch (5 touch points).
The bt541 seems to support touch keys, but the support was not added because
that functionality is not being utilized by the touchscreen used for testing.
Based on the similartities between downstream drivers, it seems likely that
other similar touchscreen ICs can be supported with this driver in the future.

Input: add driver for the Cypress CY8CTMA140 touchscreen

2020-05-10T05:26:48+00:00

This adds a new driver for the Cypress CY8CTMA140 touchscreen.

This driver is inspired by out-of-tree code for the Samsung
GT-S7710 mobile phone.

I have tried to compare the structure and behaviour of this
touchscreen to the existing CYTTSP and CYTTSP4 generics and
it seems pretty different. It is also different in character
from the cy8ctmg110_ts.c. It appears to rather be vaguely
related to the Melfas MMS114 driver, yet distinctly
different.

Dmitry Torokhov rewrote the key scanning code during the
submission process so the driver is a joint work.

Input: remove w90x900 touchscreen driver

2019-08-09T22:16:38+00:00

The ARM w90x900 platform is getting removed, so this driver is obsolete.

Input: add support for Azoteq IQS550/572/525

2019-04-30T07:38:51+00:00

This patch adds support for the Azoteq IQS550/572/525 family of
trackpad/touchscreen controllers.

The driver has been tested with an IQS550EV02 evaluation board. A
demonstration of the driver's capabilities is available here:

Input: add official Raspberry Pi's touchscreen driver

2018-12-21T09:00:27+00:00

Add's support to Raspberry Pi's 7" Touch device. Instead of using a
conventional bus all information is copied into a memory mapped area by
RPi's firmware.

Based on the driver found in RPi's kernel repository.

input: touchscreen: resistive-adc-touch: add generic resistive ADC touchscreen

2018-06-10T12:26:40+00:00

This adds a generic resistive touchscreen (GRTS) driver, which is based
on an IIO device (an ADC). It must be connected to the channels of an ADC
to receive touch data. Then it will feed the data into the input subsystem
where it registers an input device.
It uses an IIO callback buffer to register to the IIO device

Input: add support for ChipOne icn8505 based touchscreens

2018-05-09T20:29:35+00:00

The ChipOne icn8505 is an i2c capacitive touchscreen controller typically
used in cheap x86 tablets, this commit adds a driver for it.

Note the icn8505 is somewhat similar to the icn8318 and I started with
modifying that driver to support both, but in the end the differences were
too large and I decided to write a new driver instead.
