[PATCH 0/7] platform-drivers-x86: backlight, samsung and asus

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]


This series should fix a big issue when the vendor backlight is known
to work better than the ACPI backlight (and sometime it's the only
backlight that really works).

It adds a way for vendor drivers to promote themselves, still respecting
acpi_backlight=vendor|video parameters (in case the vendor driver is
wrong, and the ACPI driver works better). This way, acpi_video_register()
still works properly.

The series then add calls to this new functions in appropriates drivers,
and also blacklist a laptop where the ACPI video module is known to
break the backlight untill next reboot.


AceLan Kao (2):
  asus-wmi: control backlight power through WMI, not ACPI
  asus-wmi: enable resume on lid open

Corentin Chary (5):
  acpi: add a way to promote/demote vendor backlight drivers
  drivers-platform-x86: use acpi_video_dmi_promote_vendor()
  samsung-laptop: X360 ACPI backlight device is broken
  acpi/video_detect: blacklist samsung x360
  samsung-laptop: support R40/R41
