Peter Hurley 2c4cc91b0b drm: Fix DRM_FORCE_ON_DIGITAL use
A connector may be forced on from the command line via video=
command line setting. The digital output of dual-mode connectors
can also be specifically selected and forced on; eg., 'video=DVI-I-2:D'.
However, in this case, the connector->status will be mistakenly set to
connector_status_disconnected, and the connector will not be mode set.

Fix the connector->status when connector->force is DRM_FORCE_ON_DIGITAL.

Note that this seems to have been broken ever since the introduction
of the connector forcing support in

Chris Wilson eaf99c749d drm: Perform cmdline mode parsing during connector initialisation
i915.ko has a custom fbdev initialisation routine that aims to preserve
the current mode set by the BIOS, unless overruled by the user. The
user's wishes are determined by what, if any, mode is specified on the
command line (via the video= parameter). However, that command line mode
is first parsed by drm_fb_helper_initial_config() which is called after
i915.ko's custom initial_config() as a fallback method. So in order for
us to honour it, we need to move the cmdline parser earlier. If we
perform the connector cmdline parsing as soon as we initialise the
connector, that cmdline mode and forced status is then available even if
the fbdev helper is not compiled in or never called.

We also then expose the cmdline user mode in the connector mode lists.

v2: Rebase after connector->name upheaval.

v3: Adapt mga200 to look for the cmdline mode in the new place. Nicely
simplifies things while at that.

v4: Fix checkpatch.

v5: Select FB_CMDLINE to adapt to the changed fbdev patch.

Thomas Wood 4cf2b28146 drm/debugfs: add an "edid_override" file per connector
Add a file to debugfs for each connector to allow the EDID to be
overridden.

v2: Copy ubuf before accessing it and reject invalid length data. (David
    Herrmann)
    Ensure override_edid is reset when a new EDID value is written.

Dave Airlie 425a9a3ad1 Merge tag 'topic/core-stuff-2014-05-05' of git://anongit.freedesktop.org/drm-intel into drm-next
Update pull request with drm core patches. Mostly some polish for the
primary plane stuff and a pile of patches all over from Thierry. Has
survived a few days in drm-intel-nightly without causing ill.

I've frobbed my scripts a bit to also tag my topic branches so that you
have something stable to pull - I've accidentally pushed a bunch more
patches onto this branch before you've taken the old pull request.

Dave Airlie b87577b7c7 drm: try harder to avoid regression when merging mode bits
For QXL hw we really want the bits to be replaced as we change
the preferred mode on the fly, and the same goes for virgl when
I get to it, however the original fix for this seems to have caused
a wierd regression on Intel G33 that in a stunning display of failure
at opposition to his normal self, Daniel failed to diagnose.

So we are left doing this, ugly ugly ugly ugly, Daniel you fixed
that G33 yet?, ugly, ugly.

Andrzej Hajda f9b0e251df drm: make mode_valid callback optional
Many drm connectors do not need mode validation.
The patch makes this callback optional and removes dumb implementations.

v2: Rebase:
- imx move to a shared (but still dummy) ->mode_valid implementation.
- probe helpers have been extracted to drm_probe_helper.c

Daniel Vetter 8d75454420 drm: Split out drm_probe_helper.c from drm_crtc_helper.c
This is leftover stuff from my previous doc round which I kinda wanted
to do but didn't yet due to rebase hell.

The modeset helpers and the probing helpers a independent and e.g.
i915 uses the probing stuff but has its own modeset infrastructure. It
hence makes to split this up. While at it add a DOC: comment for the
probing libraray.

It would be rather neat to pull some of the DocBook documenting these
two helpers into in-line DOC: comments. But unfortunately kerneldoc
doesn't support markdown or something similar to make nice-looking
documentation, so the current state is better.
