25162a4f64 Input: cyttsp4 - remove driver
The cyttsp4 touchscreen driver was contributed in 2013 and since then
has seen no updates. The driver uses platform data (no device tree
support) and there are no users of it in the mainline kernel. There were
occasional fixes to it for issues either found by static code analysis
tools or via visual inspection, but otherwise the driver is completely
untested.

Remove the driver.

e8858fc07e Input: msc5000_ts - remove the driver
MCS-5000 belongs to the 1st generation of Melfas chips, manufactured in
2000-2007.

The driver relies on custom platform data (no DT support) and there
never were any users of this driver in the mainline kernel. The commit
adding the driver mentioned that the driver was tested on S3C6410 NCP
board (with Samsung S3C6410 SoC) but the touchscreen device was never
added to the board file. This board was removed in v6.3 in commit
743c8fbb90 ("ARM: s3c: remove most s3c64xx board support").

Remove the driver since there are no users.

3aa182bbc5 Input: goodix-berlin - add SPI support for Goodix Berlin Touchscreen IC
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.

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

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

5f964b0246 Input: stmpe-ts - drop obsolete dependency on COMPILE_TEST
Since commit 0166dc11be ("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.

the code bears no resemblence to the original implementation.

This driver was written strictly for the cst3xx series, but in

9958d30f38 media: Kconfig: cleanup VIDEO_DEV dependencies
media Kconfig has two entries associated to V4L API:
VIDEO_DEV and VIDEO_V4L2.

On Kernel 2.6.x, there were two V4L APIs, each one with its own flag.
VIDEO_DEV were meant to:
	1) enable Video4Linux and make its Kconfig options to appear;
	2) it makes the Kernel build the V4L core.

while VIDEO_V4L2 where used to distinguish between drivers that
implement the newer API and drivers that implemented the former one.

With time, such meaning changed, specially after the removal of
all V4L version 1 drivers.

At the current implementation, VIDEO_DEV only does (1): it enables
the media options related to V4L, that now has:

	menu "Video4Linux options"
		visible if VIDEO_DEV

	source "drivers/media/v4l2-core/Kconfig"
	endmenu

but it doesn't affect anymore the V4L core drivers.

The rationale is that the V4L2 core has a "soft" dependency
at the I2C bus, and now requires to select a number of other
Kconfig options:

	config VIDEO_V4L2
		tristate
		depends on (I2C || I2C=n) && VIDEO_DEV
		select RATIONAL
		select VIDEOBUF2_V4L2 if VIDEOBUF2_CORE
		default (I2C || I2C=n) && VIDEO_DEV

In the past, merging them would be tricky, but it seems that it is now
possible to merge those symbols, in order to simplify V4L dependencies.

Let's keep VIDEO_DEV, as this one is used on some make *defconfig
configurations.

c6ac8f0b4c Input: ili210x - add ili251x firmware update support
The ili251x firmware can be updated, this is used when switching between
different modes of operation of the touch surface, e.g. glove operation.
This patch implements the firmware update mechanism triggered by a write
into an sysfs attribute.

The firmware itself is distributed as an intel hex file with non-standard
types. The first two lines are of type 0xad, which indicates the start of
DataFlash payload, that is always at address 0xf000 on the ili251x, so it
can be dropped, and 0xac which indicates the position of firmware info in
the Application payload, that is always at address 0x2020 on the ili251x
and we do not care. The rest of the firmware is data of type 0x00, and we
care about that. To convert the firmware hex file into something usable
by the kernel, remove the first two lines and then use ihex2fw:

 $ tail -n +3 input.hex > temp.hex
 $ ./tools/firmware/ihex2fw temp.hex firmware/ilitek/ili251x.bin

To trigger the firmware update, place firmware file ilitek/ili251x.bin
into /lib/firmware/, write into firmware_update sysfs attribute and wait
about 30-40 seconds. The firmware update is slow. Afterward, verify the
firmware_version and mode sysfs attributes to check whether the firmware
got updated and the controller switched back to application (AP) mode by
reading out 'mode' attribute in sysfs.

Note that the content of firmware_version, e.g. 0600.0005.abcd.aa04 can
be matched to the content of the firmware hex file. The first four bytes,
0x06 0x00 0x00 0x05 can be found at ^:102030 00 05000006, the next four
bytes 0xab 0xcd 0xaa 0x04 at ^:10F000 00 nnnnnnnn ABCDAA04.

Note that the protocol differs considerably between the ili2xxx devices,
this patch therefore implements this functionality only for ili251x that
I can test.

e28b5c8d0a Input: touchscreen - move helper functions to core
Some devices outside of drivers/input/touchscreen/ can still make
use of the touchscreen helper functions. Therefore, it was agreed
in [1] to move them outside of drivers/input/touchscreen/ so that
other devices can call them without INPUT_TOUCHSCREEN being set.

As part of this change, 'of' is dropped from the filename because
the helpers no longer actually use OF. No changes are made to the
file contents whatsoever.

Based on the feedback in [2], the corresponding binding documents
(touchscreen.yaml and touchscreen.txt) are left in their original
locations.

676650d007 Input: resistive-adc-touch - fix kconfig dependency on IIO_BUFFER
When TOUCHSCREEN_ADC is enabled and IIO_BUFFER is disabled, it results
in the following Kbuild warning:

WARNING: unmet direct dependencies detected for IIO_BUFFER_CB
  Depends on [n]: IIO [=y] && IIO_BUFFER [=n]
  Selected by [y]:
  - TOUCHSCREEN_ADC [=y] && !UML && INPUT [=y] && INPUT_TOUCHSCREEN [=y] && IIO [=y]

The reason is that TOUCHSCREEN_ADC selects IIO_BUFFER_CB without depending
on or selecting IIO_BUFFER while IIO_BUFFER_CB depends on IIO_BUFFER. This
can also fail building the kernel.

Honor the kconfig dependency to remove unmet direct dependency warnings
and avoid any potential build failures.

26822652c8 Input: add zinitix touchscreen driver
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.

3eb66d9f97 Input: add driver for the Cypress CY8CTMA140 touchscreen
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.

Fix link error when TOUCHSCREEN_RASPBERRYPI_FW is enabled as a module and
the dependent module is built-in.  The 'depends on RASPBERRYPI_FIRMWARE' by
itself prevents the touchscreen driver from being built-in when the
firmware is configured as a module.  However, the '|| COMPILE_TEST' still
allows it unless we explicitly prevent that configuration with
'|| (RASPBERRYPI_FIRMWARE=n && COMPILE_TEST)'.
