Add #defines for the event types (EV_KEY, EV_SW, etc.) to the input DT
bindings header so that they can be used in device-tree source files.

Add a polled input driver for a keypad in which the buttons are connected

keypad are connected in a resistor ladder to an ADC. The binding
describes the mapping of ADC channel and voltage ranges to buttons.
Note that this binding only describes simple ADC keypads where only
a single button press can be

This adds an extra argument onto parse_params() to be used
as a way to make the unused callback a bit more useful and
generic by allowing the caller to pass on a data structure
of its choice. An example use case is to allow us to easily
make module parameters for every
Some devices take a long time when initializing, and not all drivers are
suited to initialize their devices when they are open. For example,
input drivers need to interrogate their devices in order to publish
device's capabilities before userspace will open them. When such drivers

Folks wishing to test enabling async probe for all built-in drivers
and/or for all modules can use
__DEBUG__kernel_force_builtin_async_probe or
__DEBUG__kernel_force_modules_async_probe kernel parameters.
Activating either one will taint your kernel.

Hi Catalin,
Today's linux-next merge of the arm64 tree got a conflict in
arch/arm64/configs/defconfig between commit c4bb799588f6 ("arm64: Add
support for Spreadtrum's Sharkl64 Platform in Kconfig and defconfig")
from the arm-soc tree and commit 475bfd3d67fa ("arm64: defconfig:
updates for 4.1")
Similarly to module_param_unsafe(), add the helper to be used by core
code wishing to expose unsafe debugging or testing parameters that taint
the kernel when set.

Because platform_driver_probe() checks, after trying to register driver,
if there are any devices that driver successfully bound to, driver's
probe routine must be run synchronously.

There are drivers that can not be probed asynchronously. One such group

Some init systems may wish to express the desire to have device drivers

Changes from v1:
-
This series adds support for the system pin and GPIO controller on the IMG
Pistachio SoC. Pistachio's system pin controller manages 99 pins, 90 of
which are MFIOs which can be muxed between multiple functions or used
as GPIOs. The GPIO control for the 90 MFIOs is broken up into banks
of 16.
Add a driver for the pin controller present on the IMG Pistachio SoC.
This driver provides pinmux and pinconfig operations as well as GPIO
and IRQ chips for the GPIO banks.

Currently the "function" + "groups" combination is the only documented
format for pinmux nodes, although many drivers use "function" + "pins".
Update the generic pinctrl binding to include the "function" + "pins"
combination as well.

Change function definition to static, move the function further up in
the file, and delete the function prototype.
