Subject: [PATCH 0/3] Kconfig dependencies: acpi-video, backlight and thermal

Hi everyone,

It took me a while to figure this out properly, as I kept getting
circular or missing dependencies with video drivers.

This set of three patches should simplify the situation a bit,
mostly by cleaning up the dependencies around CONFIG_ACPI_VIDEO.
With all three patches applied, I no longer run into those related
warnings. If everyone agrees on the general direction, I hope
we can merge all three through the DRM tree.

I originally had another larger patch in the series to replace all
of the 'select BACKLIGHT_LCD_SUPPORT; select BACKLIGHT_CLASS_DEVICE'
statements with 'depends on LCD_CLASS_DEVICE', that would clean
it up some more, but it is also a more invasive change that we
can do separately at some point.

       Arnd

Arnd Bergmann (3):
  backlight: always select BACKLIGHT_LCD_SUPPORT for
    BACKLIGHT_CLASS_DEVICE
  ACPI/DRM: rework ACPI_VIDEO Kconfig dependencies
  drm/etnaviv: add thermal dependency
