[RFC 0/6] drm: Add DRM_FBDEV_EMULATION Kconfig option

[Archit Taneja]

This provides a uniform interface to enable/disable legacy fbdev support for
modesetting drivers, based on the discussion here:

http://lists.freedesktop.org/archives/dri-devel/2015-March/078729.html

This has only been build-tested for a few devices. Mainly looking for comments
for now.

The drivers that provide fbdev emulation by default won't be impacted by
this. However, if we could make all drivers use DRM_FBDEV_EMULATION, it
would clean up individual Kconfigs, and have a centralized place where we
touch FB_* configs.

Archit Taneja (6):
  drm: Add top level Kconfig option for DRM fbdev emulation
  drm/msm: Remove local fbdev emulation Kconfig option
  drm/i915: Remove local fbdev emulation Kconfig option
  drm/tegra: Remove local fbdev emulation Kconfig option
  drm/imx: Remove local fbdev emulation Kconfig option
  drm/sti: Remove local fbdev emulation Kconfig option
