6d9b262afe platform/x86: hp-wmi: use sysfs_emit() instead of sprintf()
Follow the advice in Documentation/filesystems/sysfs.rst:
show() should only use sysfs_emit() or sysfs_emit_at() when formatting
the value to be returned to user space.

platform/x86: hp-wmi: Add thermal profile support for 8BAD boards
Add 8BAD to the list of boards which have thermal profile selection
available. This allows the CPU to draw more power than the default TDP
barrier defined by the 'balanced' thermal profile (around 50W), hence
allowing it to perform better without being throttled by the embedded
controller (around 130W).

We first need to set the HP_OMEN_EC_THERMAL_PROFILE_TIMER_OFFSET to zero.
This prevents the timer countdown from reaching zero, making the embedded
controller "force-switch" the system's thermal profile back to 'balanced'
automatically.

We also need to put a number of specific flags in
HP_OMEN_EC_THERMAL_PROFILE_FLAGS_OFFSET when we're switching to another
thermal profile:

   - for 'performance', we need to set both HP_OMEN_EC_FLAGS_TURBO and
     HP_OMEN_EC_FLAGS_NOTIMER;

   - for 'balanced' and 'powersave', we clear out the register to notify
     the system that we want to lower the TDP barrier as soon as possible.

The third flag defined in the hp_thermal_profile_omen_flags enum,
HP_OMEN_EC_FLAGS_JUSTSET, is present for completeness.

To prevent potential behaviour breakage with other Omen models, a
separate omen_timed_thermal_profile_boards array has been added to list
which boards expose this behaviour.

Performance benchmarking was done with the help of silver.urih.com and
Google Chrome 120.0.6099.129, on Gnome 45.2, with the 'performance'
thermal profile set:

|                  | Performance |     Stress |   TDP |
|------------------|-------------|------------|-------|
|    with my patch |      P84549 |    S0.1891 |  131W |
| without my patch |      P44084 |    S0.1359 |   47W |

The TDP measurements were done with the help of the s-tui utility,
during the load.

There is still work to be done:

   - tune the CPU and GPU fans to better cool down and enhance
     performance at the right time; right now, it seems that the fans are
     not properly reacting to thermal/performance events, which in turn
     either causes thermal throttling OR makes the fans spin way too long,
     even though the temperatures have lowered down

   - expose the CPU and GPU fan curves to user-land so that they can be
     controlled just like what the Omen Gaming Hub utility proposes to
     its users;

platform/x86: hp-wmi: Tidy up module source code
This commit performs four things:

   - fix up the GUID string inconsistency (lower case 'e') from the
     WMI module alias declaration/macro definition

   - separate GUID macros from the embedded controller offset macros

   - rename the description of the module to better represent what it
     actually achieves as a whole

   - add a space right before the '*' pointer qualifier to match the
     other array declarations

This also prepares the terrain for integrating support work for boards
identified as '8BAD', which corresponds to HP's Omen 17 ck2xxx models.

3df692169e platform/x86: hp-wmi: Convert to platform remove callback returning void
The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is ignored (apart
from emitting a warning) and this typically results in resource leaks.

To improve here there is a quest to make the remove callback return
void. In the first step of this quest all drivers are converted to
.remove_new(), which already returns void. Eventually after all drivers
are converted, .remove_new() will be renamed to .remove().

Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

f4a31a428d platform/x86: hp-wmi: Add HP Envy special key support
Previously, some support for certain keys on the HP keyboard has been
added already in commit 3ee5447b20 ("platform/x86: hp-wmi: Handle Omen
Key event"), however this as tested did not allow even the fn+esc key on
my HP Envy which uses the same keycode on my HP Envy x360 laptop to work
--the keycode rather than being passed in as a separate int from WMI, was
being passed in as the event_data for the HPWMI_OMEN_KEY event.

This patch, as tested was able to properly get the keycode for fn+esc,
and for fn+f12 which is supposed to be a programmable key according to
HP's keyboard diagram and is thus mapped to KEY_PROG2. The fn+f8 key
combination (mute microphone) was a standard HPWMI_BEZEL_BUTTON key,
however it did not previously have an entry in the sparse keymap. This
patch preserves the original HPWMI_OMEN_KEY behavior for laptops that
use it by only taking the keycode from the event_data only when the
event_data is nonzero.

604915f1c7 platform/x86: hp-wmi: Add HP WMI camera switch
Previously, when the camera toggle switch was hit, the hp-wmi driver
would report an invalid event code. By adding a case for that in the
event handling switch statement we can eliminate that error code and
enable a framework for potential further kernel handling of that key.
This change was tested on my HP Envy x360 15-ey0023dx laptop, but it
would likely work for any HP laptop with a camera toggle button. Now
we emit an SW_CAMERA_LENS_COVER event, on a device that gets created
on the first such event so as to not report incorrectly the state of
the camera shutter before we can know its state.

Follow up from https://lore.kernel.org/all/20230120221214.24426-1-rishitbansal0@gmail.com/

There is a "Win-Lock" key on HP Omen Laptops which supports
enabling and disabling the Windows key, which trigger commands 0x21a4
and 0x121a4 respectively. Currently the hp-wmi driver throws warnings
for this event. These can be ignored using KE_IGNORE as the
functionality is handled by the keyboard firmware itself.

3ee5447b20 platform/x86: hp-wmi: Handle Omen Key event
Add support to map the "HP Omen Key" to KEY_PROG2. Laptops in the HP
Omen Series open the HP Omen Command Center application on windows. But,
on linux it fails with the following message from the hp-wmi driver:

[ 5143.415714] hp_wmi: Unknown event_id - 29 - 0x21a5

Also adds support to map Fn+Esc to KEY_FN_ESC. This currently throws the
following message on the hp-wmi driver:

[ 6082.143785] hp_wmi: Unknown key code - 0x21a7

There is also a "Win-Lock" key on HP Omen Laptops which supports
Enabling and Disabling the Windows key, which trigger commands 0x21a4
and 0x121a4 respectively, but I wasn't able to find any KEY in input.h
to map this to.
