This driver adds support for Silead touchscreens. It has been tested
with GSL1680 and GSL3680 touch panels.
It supports ACPI and device tree enumeration. Screen resolution,
the maximum number of fingers supported and firmware name are
configurable.

smallest supported chip
This patch changes the compatibility string to match with the smallest
supported chip (EP7209). Since the DT-support for this CPU is not yet
announced, this change is safe.

In Cygnus SOC touch screen controller registers are shared with ADC and

screen driver is enhanced to support register access using syscon framework
API's to take care of mutually exclusive access.

Add device tree support for the I2C and SPI variant of AD7879(-1).
This allows to specify the touchscreen controller as a I2C client
node or SPI slave device. Most of the options available in platform
data are also available as device tree properties, the only exception
being GPIO capabilities, which can not be activated through device
tree currently.

This changes how the used gpios are stored (i.e. a struct gpio_descs
instead of two struct gpio_desc) and as with >2 gpios the states are
numbered differently the function rotary_encoder_get_state returns
unencoded numbers instead of grey encoded numbers before. The latter has
some implications on how the returned value is used and so the change is
bigger than one might expect at first.

Implement support for the following device-tree and ACPI 5.1 DSD
properties in the goodix touchscreen driver:
- touchscreen-inverted-x: X axis is inverted (boolean)
- touchscreen-inverted-y: Y axis is inverted (boolean)
- touchscreen-swapped-x-y: X and Y axis are swapped (boolean)
These are necessary on tablets which have a display in portrait
format while the touchscreen is in landscape format, such as e.g.
the MSI Primo 81.

After power on, it is recommended that the driver resets the device.
The reset procedure timing is described in the datasheet and is used
at device init (before writing device configuration) and
for power management. It is a sequence of setting the interrupt
and reset pins high/low at specific timing intervals. This procedure
also includes setting the slave address to the one specified in the
ACPI/device tree.
This is based on Goodix datasheets for GT911 and GT9271 and on Goodix
driver gt9xx.c for Android (publicly available in Android kernel
trees for various devices).
For reset the driver needs to control the interrupt and
reset gpio pins (configured through ACPI/device tree). For devices
that do not have the gpio pins properly declared, the functionality
depending on these pins will not be available, but the device can still
be used with basic functionality.
For both device tree and ACPI, the interrupt gpio pin configuration is
read from the "irq-gpios" property and the reset pin configuration is
read from the "reset-gpios" property. For ACPI 5.1, named properties
can be specified using the _DSD section. This functionality will not be
available for devices that use indexed gpio pins declared in the _CRS
section (we need to provide backward compatibility with devices
that do not support using the interrupt gpio pin as output).
For ACPI, the pins can be specified using ACPI 5.1:

- OF_IRQ=n fixes for user enabled CONFIG_OF.
- of_node_put ref counting fixes from Julia Lawall.
- Common DT binding for wakeup-source and deprecation of all similar

Some encoders have both outputs low in stable states, others also have
a stable state with both outputs high (half-period mode) and some have
a stable state in all steps (quarter-period mode). The driver used to
support the former states and with this change it can also support the
later.
This commit also deprecates the 'half-period' property and introduces
a new property 'steps-per-period'. This property specifies the
number of steps (stable states) produced by the rotary encoder
for each GPIO period.

This changAdd support for EV_ABS / EV_REL events to the gpio-keys-polled driver.
The driver already allows specifying what type of events (key / rel / abs)
a button generates when pressed, but for rel / abs axis we also need to
specify which value this specific gpio represents.
One use case is digital joysticks / direction-pads which are hooked up to
gpio, in this case we've left and right buttons which we want to map to
EV_ABS, ABS_X and we want generate events for left with a value of -1 and
for right with a value of +1 (and similar for up / down and ABS_Y).
