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.

Input: remove atmel-wm97xx touchscreen driver

2018-01-19T17:35:24+00:00

Since AVR32 arch is gone, atmel-wm97xx driver is useless. In theory it
could have been rewritten to work with AT91 devices, but the driver is from
the platform data era, and a bit hard coded to work on AVR32 hardware
variant of the AC97C peripheral, so let's remove it.

Input: add support for the Samsung S6SY761 touchscreen

2017-11-10T18:18:23+00:00

The S6SY761 touchscreen is a capicitive multi-touch controller
for mobile use. It's connected with i2c at the address 0x48.

This commit provides a basic version of the driver which can
handle only initialization, touch events and power states.

The controller is controlled by a firmware which, in the version
I currently have, doesn't provide all the possible
functionalities mentioned in the datasheet.

Input: add support for HiDeep touchscreen

2017-11-10T18:18:22+00:00

The HiDeep touchscreen device is a capacitive multi-touch controller
mainly for multi-touch supported devices use. It use I2C interface for
communication to IC and provide axis X, Y, Z locations for ten finger
touch through input event interface to userspace.

It support the Crimson and the Lime two type IC. They are different
the number of channel supported and FW size. But the working protocol
is same.
