7e93094945 drm/amd/display: Don't set mode_changed=false if the stream was removed 
[Why]
When switching from vt to desktop with EDID emulation we can receive
an atomic commit such that we have a crtc where mode_changed = true.

During the dm_update_crtc_state disable pass we remove the stream from
the context and free it on the dm_new_crtc_state.

During the enable pass we compare the new provisional stream to the
dm_old_crtc_state->stream and determine that the stream is unchanged
and no scaling has been changed.

Following this, new_crtc_state->mode_changed is then set to false.
The connectors haven't changed and the CRTC active state hasn't changed
so drm_atomic_crtc_needs_modeset returns false, so we jump to
skip_modeset and we hit:

BUG_ON(dm_new_crtc_state->stream == NULL);

...since the old stream is gone from the context and the new stream is
also still NULL.

[How]
Ensure that we still a stream to reuse before checking if we can reuse
the old stream without a full modeset.

array of available connectors. Instead we just put the useable (not

drm_client_for_each_connector_iter() everytime we probe the outputs.
Other places where it's necessary to look at the connectors, we just
iterate over them using the same iterator function.

Rename functions which signature is changed since they will be moved to
drm_client in a later patch.

a8cff4c828 drm/i915: Promote i915->mm.obj_lock to be irqsafe 
The intent is to be able to update the mm.lists from inside an irqsoff
section (e.g. from a softirq rcu workqueue), ergo we need to make the
i915->mm.obj_lock irqsafe.

v2: can_discard_pages() ensures we are shrinkable
v3: Beware shadowing of 'flags'

0bd79f915c drm/bridge/synopsys: dw-hdmi: Fix unwedge crash when no pinctrl entries 
In commit 50f9495efe ("drm/bridge/synopsys: dw-hdmi: Add "unwedge"
for ddc bus") I stupidly used IS_ERR() to check for whether we have an
"unwedge" pinctrl state even though on most flows through the driver
the unwedge state will just be NULL.

Fix it so that we consistently use NULL for no unwedge state.

be7d9f05c5 drm/gem_shmem: Use a writecombine mapping for ->vaddr 
Right now, the BO is mapped as a cached region when ->vmap() is called
and the underlying object is not a dmabuf.
Doing that makes cache management a bit more complicated (you'd need
to call dma_map/unmap_sg() on the ->sgt field everytime the BO is about
to be passed to the GPU/CPU), so let's map the BO with writecombine
attributes instead (as done in most drivers).

1bb418bffd drm/omap: add support for manually updated displays 
This adds the required infrastructure for manually updated displays,
such as DSI command mode panels. While those panels often support
partial updates we currently always do a full refresh.

The display will be refreshed when something calls the dirty callback,
such as libdrm's drmModeDirtyFB(). This is currently being done at least
by the kernel console and Xorg (with modesetting driver) in their
default configuration. Weston does not implement this and the fbdev
backend does not work (display will not update). Weston's DRM backend
uses double buffering and the page flip will also trigger a display
refresh.

is not true for DSI. DSI calculates the VM for DISPC based on its
own, but it's not identical. Actually the DSI VM is not even a valid
DISPC VM making this check fail. Let's restore the old behaviour
and avoid checking the DISPC VM for DSI here.
