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.

HID: hid-appletb-kbd: add driver for the keyboard mode of Apple Touch Bars

2025-02-07T13:03:50+00:00

The Touch Bars found on x86 Macs support two USB configurations: one
where the device presents itself as a HID keyboard and can display
predefined sets of keys, and one where the operating system has full
control over what is displayed. This commit adds a driver for the
display functionality of the first configuration.

Note that currently only T2 Macs are supported.

This driver is based on previous work done by Ronald Tschalär
.

HID: topre: Fix n-key rollover on Realforce R3S TKL boards

2025-02-03T21:59:42+00:00

Newer model R3* Topre Realforce keyboards share an issue with their older
R2 cousins where a report descriptor fixup is needed in order for n-key
rollover to work correctly, otherwise only 6-key rollover is available.
This patch adds some new hardware IDs for the R3S 87-key keyboard and
makes amendments to the existing hid-topre driver in order to change the
correct byte in the new model.
