[PATCH 0/8] drm, fbdev: rework dependencies

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

 



I tried to fix up some dependencies after the sii8620 "imply EXTCON"
statementn broke, trying a few things but in the backing out a
change that would completely reverse the LEDS_CLASS selects into
a 'depends on'. 

However, what I got now are multiple changes that remove gratious
"selects" that lead to circular dependencies for sii8620 and others:

- Anything doing "select FB" is now gone, or becomes "depends on FB",

- DDC support depends on I2C instead of selecting it

- backlight class device support is never selected by framebuffer
  drivers but has proper dependencies

I have done thousands of randconfig build tests on this, but no
runtime tests.

Some of the 'depends on FOO || !FOO' statements could be simplified
into a new 'uses FOO' syntax based on a patch from Saeed Mahameed,
but I would for the moment treat that as a cleanup that can be done
later.

If we can agree on these changes, maybe someone can merge them
through the drm-misc tree.

Please review
