Input: novatek-nvt-ts - add touchscreen model number to description

2023-07-10T18:50:38+00:00

A phoronix forum member actual found documentation on what the model
number for the touchscreen controller on the Acer Iconia One 7 B1-750 is.

Update the driver's description to include this.

Input: add HAS_IOPORT dependencies

2023-05-22T22:17:09+00:00

In a future patch HAS_IOPORT=n will result in inb()/outb() and friends
not being declared. We thus need to add HAS_IOPORT as dependency for
those drivers using them.

Input: edt-ft5x06 - select REGMAP_I2C

2023-04-10T23:56:47+00:00

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

2023-04-02T05:42:26+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: stmpe-ts - drop obsolete dependency on COMPILE_TEST

2022-11-22T22:20:28+00:00

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

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