Mark Pearson dc8c9c171e Input: atkbd - map F23 key to support default copilot shortcut 
commit 907bc9268a upstream.

Microsoft defined Meta+Shift+F23 as the Copilot shortcut instead of a
dedicated keycode, and multiple vendors have their keyboards emit this
sequence in response to users pressing a dedicated "Copilot" key.
Unfortunately the default keymap table in atkbd does not map scancode
0x6e (F23) and so the key combination does not work even if userspace
is ready to handle it.

Because this behavior is common between multiple vendors and the
scancode is currently unused map 0x6e to keycode 193 (KEY_F23) so that
key sequence is generated properly.

MS documentation for the scan code:
https://learn.microsoft.com/en-us/windows/win32/inputdev/about-keyboard-input#scan-codes
Confirmed on Lenovo, HP and Dell machines by Canonical.
Tested on Lenovo T14s G6 AMD.

Nuno Sa 195e42c9a9 Input: adp5589-keys - fix adp5589_gpio_get_value() 
commit c684771630 upstream.

The adp5589 seems to have the same behavior as similar devices as
explained in commit 910a9f5636 ("Input: adp5588-keys - get value from
data out when dir is out").

Basically, when the gpio is set as output we need to get the value from
ADP5589_GPO_DATA_OUT_A register instead of ADP5589_GPI_STATUS_A.

Nuno Sa 7c3f04223a Input: adp5589-keys - fix NULL pointer dereference 
commit fb5cc65f97 upstream.

We register a devm action to call adp5589_clear_config() and then pass
the i2c client as argument so that we can call i2c_get_clientdata() in
order to get our device object. However, i2c_set_clientdata() is only
being set at the end of the probe function which means that we'll get a
NULL pointer dereference in case the probe function fails early.

Nuno Sa 2a26c3122d Input: adp5588-keys - fix check on return code 
commit eb017f4ea1 upstream.

During adp5588_setup(), we read all the events to clear the event FIFO.
However, adp5588_read() just calls i2c_smbus_read_byte_data() which
returns the byte read in case everything goes well. Hence, we need to
explicitly check for a negative error code instead of checking for
something different than 0.

Hans de Goede ac589a37bc Input: atkbd - skip ATKBD_CMD_SETLEDS when skipping ATKBD_CMD_GETID 
commit 683cd8259a upstream.

After commit 936e4d49ec ("Input: atkbd - skip ATKBD_CMD_GETID in
translated mode") the keyboard on Dell XPS 13 9350 / 9360 / 9370 models
has stopped working after a suspend/resume.

The problem appears to be that atkbd_probe() fails when called
from atkbd_reconnect() on resume, which on systems where
ATKBD_CMD_GETID is skipped can only happen by ATKBD_CMD_SETLEDS
failing. ATKBD_CMD_SETLEDS failing because ATKBD_CMD_GETID was
skipped is weird, but apparently that is what is happening.

Fix this by also skipping ATKBD_CMD_SETLEDS when skipping
ATKBD_CMD_GETID.

commit 58f65f9db7 upstream.

Barnabás reported that the change to skip the getid command
when the controller is in translated mode on laptops caused
the Version field of his "AT Translated Set 2 keyboard"
input device to change from ab83 to abba, breaking a custom
hwdb entry for this keyboard.

Use the standard ab83 id for keyboards when getid is skipped
(rather then that getid fails) to avoid reporting a different
Version to userspace then before skipping the getid.

Hans de Goede 274333f825 Input: atkbd - skip ATKBD_CMD_GETID in translated mode 
[ Upstream commit 936e4d49ec ]

There have been multiple reports of keyboard issues on recent laptop models
which can be worked around by setting i8042.dumbkbd, with the downside
being this breaks the capslock LED.

It seems that these issues are caused by recent laptops getting confused by
ATKBD_CMD_GETID. Rather then adding and endless growing list of quirks for
this, just skip ATKBD_CMD_GETID alltogether on laptops in translated mode.

The main goal of sending ATKBD_CMD_GETID is to skip binding to ps/2
mice/touchpads and those are never used in translated mode.

Examples of laptop models which benefit from skipping ATKBD_CMD_GETID:

* "HP Laptop 15s-fq2xxx", "HP laptop 15s-fq4xxx" and "HP Laptop 15-dy2xxx"
  models the kbd stops working for the first 2 - 5 minutes after boot
  (waiting for EC watchdog reset?)

* On "HP Spectre x360 13-aw2xxx" atkbd fails to probe the keyboard

* At least 9 different Lenovo models have issues with ATKBD_CMD_GETID, see:
  https://github.com/yescallop/atkbd-nogetid

This has been tested on:

1. A MSI B550M PRO-VDH WIFI desktop, where the i8042 controller is not
   in translated mode when no keyboard is plugged in and with a ps/2 kbd
   a "AT Translated Set 2 keyboard" /dev/input/event# node shows up

2. A Lenovo ThinkPad X1 Yoga gen 8 (always has a translated set 2 keyboard)

While at it, invert the error checking logic to simplify code flow.

Rob Herring dbce1a7d5d Input: Explicitly include correct DT includes 
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.

Uwe Kleine-König 6906f5060d Input: iqs62x-keys - suppress duplicated error message in .remove() 
If a platform driver's remove callback returns non-zero the driver core
emits an error message. In such a case however iqs62x_keys_remove()
already issued a (better) message. So return zero to suppress the
generic message.

This patch has no other side effects as platform_remove() ignores the
return value of .remove() after the warning.
