platform: x86: MLX_PLATFORM: select REGMAP instead of depending on it

2023-03-07T10:37:27+00:00

REGMAP is a hidden (not user visible) symbol. Users cannot set it directly thru "make *config", so drivers should select it instead of depending on it if they need it. Consistently using "select" or "depends on" can also help reduce Kconfig circular dependency issues. Therefore, change the use of "depends on REGMAP" to "select REGMAP".

platform/x86: apple_gmux: Drop no longer used ACPI_VIDEO Kconfig dependency

2023-02-02T21:48:20+00:00

The apple_gmux code no longer uses any symbols from the ACPI_VIDEO code, so that dependency can be dropped. Signed-off-by: Hans de Goede Link: https://lore.kernel.org/r/20230123154512.852921-1-hdegoede@redhat.com

platform/x86: Move existing HP drivers to a new hp subdir

2022-11-16T07:48:19+00:00

The purpose of this patch is to provide a central location where all HP related drivers are found. HP drivers will recide under drivers/platform/x86/hp directory. Introduce changes to Kconfig file to list all HP driver under "HP X86 Platform Specific Device Drivers" menu option. Additional changes include update MAINTAINERS file to indicate hp related drivers new path.

platform/x86: Battery charge mode in toshiba_acpi (sysfs)

2022-09-09T19:58:16+00:00

This commit adds the ACPI battery hook which in turns adds the sysfs entries. Because the Toshiba laptops only support two modes (eco or normal), which in testing correspond to 80% and 100% we simply round to the nearest possible level when set. It is possible that Toshiba laptops other than the Z830 has different set points for the charging. If so, a quirk table could be introduced in the future for this. For now, assume that all laptops that support this feature work the same way. Tested on a Toshiba Satellite Z830.

platform/x86: nvidia-wmi-ec-backlight: Use acpi_video_get_backlight_type()

2022-09-03T10:17:26+00:00

Add an acpi_video_get_backlight_type() == acpi_backlight_nvidia_wmi_ec check. This will make nvidia-wmi-ec-backlight properly honor the user selecting a different backlight driver through the acpi_backlight=... kernel commandline option. Since the auto-detect code check for nvidia-wmi-ec-backlight in drivers/acpi/video_detect.c already checks that the WMI advertised brightness-source is the embedded controller, this new check makes it unnecessary for nvidia_wmi_ec_backlight_probe() to check this itself.

platform/x86: p2sb: Move out of X86_PLATFORM_DEVICES dependency

2022-08-01T14:26:38+00:00

The P2SB library is used for various drivers, including server platforms. That's why the dependency on X86_PLATFORM_DEVICES seems superfluous.

platform/x86: asus-wmi: Add mic-mute LED classdev support

2022-07-14T20:02:57+00:00

In some new ASUS devices, hotkey Fn+F13 is used for mic mute. If mic-mute LED is present by checking WMI ASUS_WMI_DEVID_MICMUTE_LED, we will add a mic-mute LED classdev, asus::micmute, in the asus-wmi driver to control it. The binding of mic-mute LED controls will be swithched with LED trigger.

platform/x86: panasonic-laptop: filter out duplicate volume up/down/mute keypresses

2022-06-28T19:45:40+00:00

On some Panasonic models the volume up/down/mute keypresses get reported both through the Panasonic ACPI HKEY interface as well as through the atkbd device. Filter out the atkbd scan-codes for these to avoid reporting presses twice. Note normally we would leave the filtering of these to userspace by mapping the scan-codes to KEY_UNKNOWN through /lib/udev/hwdb.d/60-keyboard.hwdb. However in this case that would cause regressions since we were filtering the Panasonic ACPI HKEY events before, so filter these in the kernel.
