47340e46f3 drm/omap: fix possible object reference leak 
The call to of_find_matching_node returns a node pointer with refcount
incremented thus it must be explicitly decremented after the last
usage.

dma-bufs are device coherent, with explicit CPU synchronisation provided
via the begin/end cpu access ioctls. As the coherency of the dma-buf is
explicitly defined to be under user control, flushing any caches on
attach/detach of the dma-buf is additional work that doesn't aide the
user in the slightest.

c631cc8f11 drm/i915: Make a copy of the ggtt view for slave plane 
intel_prepare_plane_fb() will always pin plane_state->hw.fb whenever
it is present. We copy that from the master plane to the slave plane,
but we fail to copy the corresponding ggtt view. Thus when it comes time
to pin the slave plane's fb we use some stale ggtt view left over from
the last time the plane was used as a non-slave plane. If that previous
use involved 90/270 degree rotation or remapping we'll try to shuffle
the pages of the new fb around accordingingly. However the new
fb may be backed by a bo with less pages than what the ggtt view
rotation/remapped info requires, and so we we trip a GEM_BUG().

Steps to reproduce on icl:
1. plane 1: whatever
   plane 6: largish !NV12 fb + 90 degree rotation
2. plane 1: smallish NV12 fb
   plane 6: make invisible so it gets slaved to plane 1
3. GEM_BUG()

ff1ca6397b drm/bridge: Add tc358768 driver 
Add basic support for the Toshiba TC358768 RGB to DSI bridge.
Not all the features of the TC358768 is implemented by the initial driver:
MIPI_DSI_MODE_VIDEO and MIPI_DSI_FMT_RGB888 is only supported and tested.

Only write is implemented for mipi_dsi_host_ops.transfer.

8a6483ac63 drm/bridge: tc358767: fix poll timeouts 
Link training fails with:

  Link training timeout waiting for LT_LOOPDONE!
  main link enable error: -110

This is caused by too tight timeouts, which were changed recently in
aa92213f38 ("drm/bridge: tc358767: Simplify polling in tc_link_training()").

With a quick glance, the commit does not change the timeouts. However,
the method of delaying/sleeping is different, and as the timeout in the
previous implementation was not explicit, the new version in practice
has much tighter timeout.

The same change was made to other parts in the driver, but the link
training timeout is the only one I have seen causing issues.
Nevertheless, 1 us sleep is not very sane, and the timeouts look pretty
tight, so lets fix all the timeouts.

One exception was the aux busy poll, where the poll sleep was much
longer than necessary (or optimal).

I measured the times on my setup, and now the sleep times are set to
such values that they result in multiple loops, but not too many (say,
5-10 loops). The timeouts were all increased to 100ms, which should be
more than enough for all of these, but in case of bad errors, shouldn't
stop the driver as multi-second timeouts could do.

If the module happens to be loaded later at runtime there is a chance
memory is already fragmented enough to fail allocation of firmware
blob storage and consequently GVT init. Since it doesn't seem to be
necessary to have the blob contiguous, use vmalloc() instead to avoid
the issue.
