1b30ab0c40 drm/omapdrm: dispc: Refuse x-decimation above 4 for all but 8-bit formats 
Let's disable all scaling that requires horizontal decimation with
higher factor than 4, until we have better estimates of what we can
and can not do. However, NV12 color format appears to work Ok with
all decimation factors.

When decimating horizontally by more that 4 the dss is not able to
fetch the data in burst mode. When this happens it is hard to tell if
there enough bandwidth. Despite what theory says this appears to be
true also for 16-bit color formats.

897145d0c7 drm/omapdrm: Move commit_modeset_enables() before commit_planes() 
Move drm_atomic_helper_commit_modeset_enables() call to before
drm_atomic_helper_commit_planes() call and have a
omap_atomic_wait_for_completion() call after both.

With the current dss dispc implementation we have to enable the new
modeset before we can commit planes. The dispc ovl configuration
relies on the video mode configuration been written into the HW when
the ovl configuration is calculated.

This approach is not ideal because after a mode change the plane
update is executed only after the first vblank interrupt. The dispc
implementation should be fixed so that it is able use uncommitted drm
state information.  information.

aa9323dd49 drm/i915: Avoid spurious WARNs about the wrong pipe in the PPS code 
Until recently vlv_steal_power_sequencer() wasn't being called for
normal DP ports, and hence it could assert that it should only be
called for pipe A and B (since pipe C doesn't support eDP). However
that changed when we started to consider normal DP ports as well when
choosing a PPS. So we will now get spurious warnings when
vlv_steal_power_sequencer() does get called for pipe C. Avoid this by
moving the WARN down into vlv_detach_power_sequencer() where this
assertion should still hold.

ec62ed3e1d drm/i915: Restore context and pd for ringbuffer submission after reset 
Following a reset, the context and page directory registers are lost.
However, the queue of requests that we resubmit after the reset may
depend upon them - the registers are restored from a context image, but
that restore may be inhibited and may simply be absent from the request
if it was in the middle of a sequence using the same context. If we
prime the CCID/PD registers with the first request in the queue (even
for the hung request), we prevent invalid memory access for the
following requests (and continually hung engines).

v2: Magic BIT(8), reserved for future use but still appears unused.
v3: Some commentary on handling innocent vs guilty requests
v4: Add a wait for PD_BASE fetch. The reload appears to be instant on my
Ivybridge, but this bit probably exists for a reason.

The max link parameters should be set/reset only on HPD or

Add a flag reset_link_params to intel_dp to decide when
to reset the max link parameters. This prevents the parameters
from getting reset/overwritten through all other
connector->funcs->detect() calls. This is important when link
training fails and the max link params are modified to the

1592364de3 drm: Resurrect atomic rmfb code, v3 
This was somehow lost between v3 and the merged version in Maarten's
patch merged as:

commit f2d580b9a8
Author: Maarten Lankhorst <maarten.lankhorst@linux.intel.com>
Date:   Wed May 4 14:38:26 2016 +0200

    drm/core: Do not preserve framebuffer on rmfb, v4.

This introduces a slight behavioral change to rmfb. Instead of
disabling a crtc when the primary plane is disabled, we try to
preserve it.

Apart from old versions of the vmwgfx xorg driver, there is
nothing depending on rmfb disabling a crtc. Since vmwgfx is
a legacy driver we can safely only disable the plane with atomic.

If this commit is rejected by the driver then we will still fall
back to the old behavior and turn off the crtc.

v2:
- Remove plane->fb assignment, done by drm_atomic_clean_old_fb.
- Add WARN_ON when atomic_remove_fb fails.
- Always call drm_atomic_state_put.
v3:
- Use drm_drv_uses_atomic_modeset
- Handle the case where the first plane-disable-only commit fails
  with -EINVAL. Some drivers do not support this, fall back to
  disabling all crtc's in this case.
