[PATCH v2 0/9] drm/fb-helper: Deferred setup support

[Thierry Reding]

From: Thierry Reding <treding at nvidia.com>

This set of patches adds support for deferring FB helper setup, which is
useful to obtain a sane configuration even when no outputs are available
during probe.

One example is HDMI, where fbdev will currently fallback to a 1024x786
resolution if no monitor is connected, and will then forever stay that
way. With these patches, the FB helpers will take note that it doesn't
make sense to setup fbdev yet and will defer until a monitor is
connected, at which point the preferred mode will be selected.
