These drivers don't use the driver_data member of struct i2c_device_id,
so don't explicitly initialize this member.
This prepares putting driver_data in an anonymous union which requires
either no initialization or named designators. But it's also a nice
cleanup on its own.
While add it, also remove commas after the sentinel entries.

The DT of_device.h and of_platform.h date back to the separate
of_platform_bus_type before it as merged into the regular platform bus.
As part of that merge prepping Arm DT support 13 years ago, they
"temporarily" include each other. They also include platform_device.h
and of.h. As a result, there's a pretty much random mix of those include
files used throughout the tree. In order to detangle these headers and
replace the implicit includes with struct declarations, users need to
explicitly include the correct includes.

After commit b8a1a4cd5a98 ("i2c: Provide a temporary .probe_new()
call-back type"), all drivers being converted to .probe_new() and then
03c835f498b5 ("i2c: Switch .probe() to not take an id parameter") convert
back to (the new) .probe() to be able to eventually drop .probe_new() from
struct i2c_driver.

The driver will match mostly by DT table (even thought there is regular
ID table) so there is little benefit in of_match_ptr (this also allows
ACPI matching via PRP0001, even though it might not be relevant here).
This also fixes !CONFIG_OF error:
drivers/input/keyboard/tm2-touchkey.c:335:34: error: ‘tm2_touchkey_of_match’ defined but not used [-Werror=unused-const-variable=]

SIMPLE_DEV_PM_OPS() is deprecated as it requires explicit protection
against unused function warnings. The new combination of pm_sleep_ptr()
and DEFINE_SIMPLE_DEV_PM_OPS() allows the compiler to see the functions,
thus suppressing the warning, but still allowing the unused code to be
removed. Thus also drop the __maybe_unused markings.

At the moment the touch keys have key codes assigned from the device
tree. In some cases, users might want to change the key code from
userspace. There is existing functionality for this in the input core
using the EVIOCSKEYCODE ioctl, which is integrated for example into udev.
Make it possible to use this functionality for tm2-touchkey by simply
making the input core aware of the array that holds the keycodes.
Similar code also exists in mcs_touchkey and mpr121_touchkey.

Report the index of pressed touch key as MSC_SCAN code to userspace
so it is possible to identify which of the keys was pressed (not
just the function that is currently assigned to the key).
This is done similarly also in mcs_touchkey and mpr121_touchkey.

The Samsung touchkey controllers are often used with external pull-up
for the interrupt line and the I2C lines, so we might need to enable
a regulator to bring the lines into usable state. Otherwise, this might
cause spurious interrupts and reading from I2C will fail.
Implement support for a "vddio-supply" that is enabled by the
tm2-touchkey driver so that the regulator gets enabled when needed.

We need to access I2C bus when switching brightness, and that may block,
therefore we have to set stmfts_brightness_set() as LED's
brightness_set_blocking() method.

on actual hardware.

Commit 4e552c8cb5bc ("leds: add LED_ON brightness as boolean value")
has introduced the LED_ON enumeration value that can be used
instead of LED_FULL which has more of a linear value.
Because the tm2-touchscreen doesn't have brightness levels, but
it's a simple on/off led, use LED_ON instead of LED_FULL.

This patch adds support for the TM2 touch key and led functionality.

KEY_PHONE and KEY_BACK event types. LED brightness can be controlled by
"/sys/class/leds/tm2-touchkey/brightness".
