Uwe Kleine-König
7dde4e7474 Input: rotary-encoder - support more than 2 gpios as input
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.

ec6e1b4082 Input: goodix - reset device at init
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:

Pull DeviceTree updates from Rob Herring:
 "A fairly large (by DT standards) pull request this time with the
  majority being some overdue moving DT binding docs around to
  consolidate similar bindings.

   - DT binding doc consolidation moving similar bindings to common
     locations.  The majority of these are display related which were
     scattered in video/, fb/, drm/, gpu/, and panel/ directories.

   - Add new config option, CONFIG_OF_ALL_DTBS, to enable building all
     dtbs in the tree for most arches with dts files (except powerpc for
     now).

   - 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
     bindings.

   - DT binding for PXA LCD controller.

   - Allow ignoring failed PCI resource translations in order to ignore
     64-bit addresses on non-LPAE 32-bit kernels.

   - Support setting the NUMA node from DT instead of only from parent
     device.

   - Couple of earlycon DT parsing fixes for address and options"

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.

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).

62f4666968 Input: zforce - make the interrupt GPIO optional
Add support for hardware which uses an I2C Serializer / Deserializer
(SerDes) to communicate with the zFroce touch driver. In this case the
SerDes will be configured as an interrupt controller and the zForce driver
will have no access to poll the GPIO line.

To support this, we add two dedicated new GPIOs in the device tree:
reset-gpios and irq-gpios, with the irq-gpios being optional.

To not break the existing device trees, the index based 'gpios' entries
are still supported, but marked as deprecated.

With this, if the interrupt GPIO is available, either via the old or new
device tree style, the while loop will read and handle the packets as long
as the GPIO indicates that the interrupt is asserted (existing, unchanged
driver behavior).

If the interrupt GPIO isn't available, i.e. not configured via the new
device tree style, we are falling back to one read per ISR invocation
(new behavior to support the SerDes).

Note that the gpiod functions help to handle the optional GPIO:
devm_gpiod_get_index_optional() will return NULL in case the interrupt
GPIO isn't available. And gpiod_get_value_cansleep() does cover this, too,
by returning 0 in this case.
