HID: lenovo: Use KEY_PERFORMANCE instead of ACPI's platform_profile

2025-09-12T14:59:05+00:00

Commit 84c9d2a968c82 ("HID: lenovo: Support for ThinkPad-X12-TAB-1/2 Kbd
Fn keys") added a dependency on ACPI's platform_profile. This should not
be done for generic USB devices as this prevents using the devices on
non ACPI devices like Apple silicon Macs and other non-ACPI arm64
systems. An attempt to allow using platform_profile on non-ACPI systems
was rejected in [1] and instead platform_profile was made to fail during
init in commit dd133162c9cf ("ACPI: platform_profile: Avoid initializing
on non-ACPI platforms").
So remove the broken dependency and instead let's user space handle this
keycode by sending the new KEY_PERFORMANCE. Stable backport depends on
commit 89c5214639294 ("Input: add keycode for performance mode key").

HID: multitouch: add device ID for Apple Touch Bar

2025-06-11T09:25:26+00:00

This patch adds the device ID of Apple Touch Bar found on x86 MacBook Pros
to the hid-multitouch driver.

Note that this is device ID is for T2 Macs. Testing on T1 Macs would be
appreciated.

HID: HID_APPLETB_BL should depend on X86

2025-04-24T10:32:02+00:00

The Apple Touch Bar is only present on x86 MacBook Pros.  Hence add a
dependency on X86, to prevent asking the user about this driver when
configuring a kernel for a different architecture.

Merge branch 'for-6.15/pidff' into for-linus

2025-03-26T12:54:04+00:00

From: Tomasz Pakuła 

This patch series is focused on improving the compatibility and usability of the
hid-pidff force feedback driver. Last patch introduces a new, universal driver
for PID devices that need some special handling like report fixups, remapping the
button range, managing new pidff quirks and setting desirable fuzz/flat values.

This work has been done in the span of the past months with the help of the great
Linux simracing community, with a little input from sim flight fans from FFBeast.

No changes interfere with compliant and currently working PID devices.
"Generic" codepath was tested as well with Moza and Simxperience AccuForce v2.

I'm not married to the name. It's what we used previously, but if "universal" is
confusing (pidff is already the generic driver), we can come up with something
better like "hid-quirky-pidff" :)

With v8 and  tiny finx in v9, all the outstanding issues were resolved,
additional pidff issues were fixed and hid-pidff defines moved to a dedicated
header file. This patch series could be considered done bar any comments and
requests from input maintainers.

I could save more then a dozen lines of code by changing simple if statements
to only occupy on line instead of two in there's a need for that.

HID: Kconfig: Add LEDS_CLASS_MULTICOLOR dependency to HID_LOGITECH

2025-02-11T06:30:31+00:00

The test bot found an issue with building hid-lg-g15.

All errors (new ones prefixed by >>):

   powerpc-linux-ld: drivers/hid/hid-lg-g15.o: in function `lg_g510_kbd_led_write':
>> drivers/hid/hid-lg-g15.c:241:(.text+0x768): undefined reference to `led_mc_calc_color_components'

>> drivers/hid/hid-lg-g15.c:686:(.text+0xa9c): undefined reference to `devm_led_classdev_multicolor_register_ext'

Since multicolor LED APIs manage the keyboard backlight settings of
hid-lg-g15, the LEDS_CLASS_MULTICOLOR dependency was added to
HID_LOGITECH.

HID: hid-appletb-kbd: add support for automatic brightness control while using the touchbar

2025-02-07T13:03:56+00:00

On Windows, if there is no input by the user for 60 sec, the Touch Bar dims
automatically, and after further 15 sec, it turns off. On receiving input,
the Touch Bar resets the timer and goes back to full brightness. This patch
implements the same functionality.
