1a644cd47c drm: extract dp link train delay functions from radeon
This requires a few changes since that dpcd value is above the
range currently cached by radeon. I've check the dp specs, and
above 0xf there's a big gap and nothing that looks like we should
cache it while a given device is plugged in. It's also the same value
that i915.ko uses.

Hence extend the various dpcd arrays in the radeon driver, use
proper symbolic constants where applicable (one place overallocated
the dpcd array to 25 bytes). Then also drop the rd_interval cache -
radeon_dp_link_train_init re-reads the dpcd block, so the values we'll
consume in train_cr and train_ce will always be fresh.

To avoid needless diff-churn, #define the old size of dpcd as the new
one and keep it around.

v2: Alex Deucher noticed one place where I've forgotten to replace 8
with DP_RECEIVER_CAP_SIZE.

612a9aab56 Merge branch 'drm-next' of git://people.freedesktop.org/~airlied/linux
Pull drm merge (part 1) from Dave Airlie:
 "So first of all my tree and uapi stuff has a conflict mess, its my
  fault as the nouveau stuff didn't hit -next as were trying to rebase
  regressions out of it before we merged.

  Highlights:
   - SH mobile modesetting driver and associated helpers
   - some DRM core documentation
   - i915 modesetting rework, haswell hdmi, haswell and vlv fixes, write
     combined pte writing, ilk rc6 support,
   - nouveau: major driver rework into a hw core driver, makes features
     like SLI a lot saner to implement,
   - psb: add eDP/DP support for Cedarview
   - radeon: 2 layer page tables, async VM pte updates, better PLL
     selection for > 2 screens, better ACPI interactions

  The rest is general grab bag of fixes.

  So why part 1? well I have the exynos pull req which came in a bit
  late but was waiting for me to do something they shouldn't have and it
  looks fairly safe, and David Howells has some more header cleanups
  he'd like me to pull, that seem like a good idea, but I'd like to get
  this merge out of the way so -next dosen't get blocked."

Tons of conflicts mostly due to silly include line changes, but mostly
mindless.  A few other small semantic conflicts too, noted from Dave's
pre-merged branch.

Remove redundant DRM UAPI header #inclusions from drivers/gpu/.

Remove redundant #inclusions of core DRM UAPI headers (drm.h, drm_mode.h and
drm_sarea.h).  They are now #included via drmP.h and drm_crtc.h via a preceding
patch.

Without this patch and the patch to make include the UAPI headers from the core
headers, after the UAPI split, the DRM C sources cannot find these UAPI headers
because the DRM code relies on specific -I flags to make #include "..."  work
on headers in include/drm/ - but that does not work after the UAPI split without
adding more -I flags.

57b35e29cf drm/radeon: work around KMS modeset limitations in PLL allocation (v2)
Since the current KMS API sets the mode independantly on
each crtc, we may end up with resource conflicts.  The PLL
allocation is one of those cases.  In the following example
we have 3 crtcs in use driving 2 DVI connectors and 1 DP
connector.  On the initial kernel modeset for fbdev, the
display topology ends up as follows:

crtc0 -> DP-0
crtc1 -> DVI-0
crtc2 -> DVI-1

Because this is the first modeset, all of the PLLs are
available as none have been assigned.  So we end up with
the following:

crtc0 uses DCPLL
crtc1 uses PPLL2
crtc2 uses PPLL1

When X starts, it assigns a different topology:

crtc0 -> DVI-0
crtc1 -> DP-0
crtc2 -> DVI-1

However, since the KMS API is per crtc, we set the mode on each
crtc independantly.  When it comes time to set the mode on crtc0,
the topology for crtc1 and crtc2 are still intact.  crtc1 and
crtc2 are already assigned PPLL2 and PPLL1 so when it comes time
to set the mode on crtc0, crtc1 and crtc2 have not been torn down
yet, so there appears to be no PLLs available.  In reality, we
are reconfiguring the entire display topology, however, since
each crtc is handled independantly, we don't know that in the
driver at each crtc mode set time.

This patch checks to see if the same connector is being driven by
another crtc, and if so, uses the PLL already associated with it.

v2: store connector in the radeon crtc struct, simplify checking.

    when the add-on card is not plugged in or HDMI is disabled in BIOS setup.
    In this case, drm_get_edid() and drm_edid_block_valid() periodically
    dump data and kernel errors into system log files and onto terminals.
    For these connectors DDC probing is extended by a check for a correct
    EDID header. Only in case a valid EDID header is also found, the
    (HDMI or DVI) connector will be used by the Radeon driver. This prevents
    the kernel driver from useless flooding of logs and terminal sessions with
    EDID dumps and error messages.
    This patch adds a flag 'requires_extended_probe' to the radeon_connector
    structure. In function radeon_connector_needs_extended_probe() this flag
    can be set on a chipset family/vendor/connector type specific basis.
    In addition, function radeon_ddc_probe() has been adapted to perform
    extended DDC probing if required by the connector's flag.
    Requires function drm_edid_header_is_valid() in DRM module provided by
    [PATCH] drm: Separate EDID Header Check from EDID Block Check.

    Tested for kernel 2.6.35, 2.6.38 and 3.0 on Asus M2A-VM HDMI board

1e85e1d07b drm/radeon/kms: simplify hotplug handler logic
In the hotplug handler, just use the drm dpms functions.
If the monitor is plugged in, turn it on, if it's not,
turn it off.  This also reduces power usage by turning
off the encoder and crtc when the monitor is unplugged.
