40aeab044a drm/doc/rfc: Introduce the merge plan for the Xe driver. 
Let’s establish a merge plan for Xe, by writing down clear pre-merge goals, in
order to avoid unnecessary delays.

This initial document starts with a TODO list containing items with clear and
measurable key results. Xe’s initial pull request should only be sent to
dri-devel after all the items are clearly resolved.

Since many of them involve some level of a community consensus, in many cases,
the consensus will be reached in follow-up patches to this document with more
details of the API or helpers that will be developed or modified.

Besides of the items that are highlighted in this document, it is important
to highlight that Oded, has been volunteered to give the overall ack on Xe
driver as the way to confirm that it looks good for upstream.

v2: Incorporated Daniel's feedback:
    - Do not make long-running compute a blocker.
    - Add a mention to drm-exec that that ties to vm_bind and long-running
      compute jobs. Then I also added GPUVA since I recently noticed that this
      ties also to the work Matt is doing on that front.
    - Added the devcoredump section.
    - Add the mention to Oded being volunteered for the overall ack.

v3: Reword a bit the Async VM_BIND to incorporate Daniel's feedback on ensuring
    the async vmbind consensus explicitly include Mesa, besides other kernel
    drivers.

a03f028542 drm/vkms: allow full alpha blending on all planes 
Before commit bc0d7fdefe ("drm: vkms: Supports to the case where
primary plane doesn't match the CRTC"), the composition was executed on
top of the primary plane. Therefore, the primary plane was not able to
support the alpha channel. After commit bc0d7fdefe, this is possible,
as the composition is now executed on top of the CRTC.

So, allow all planes to support the alpha channel, making full alpha
blending possible in vkms.

94545f2715 arch/x86: Include <asm/fb.h> in fbdev source file 
Move the implementation of fb_pgprotect() to fbdev.c and include
<asm/fb.h>. Fixes the following warning:

  ../arch/x86/video/fbdev.c:14:5: warning: no previous prototype for 'fb_is_primary_device' [-Wmissing-prototypes]
     14 | int fb_is_primary_device(struct fb_info *info)
        |     ^~~~~~~~~~~~~~~~~~~~

Just including <asm/fb.h> results in a number of built-in errors
about undefined function. Moving fb_pgprotect() to the source file
avoids the required include statements in the header. The function
is only called occasionally from fb_mmap(), [1] so having it as static
inline had no benefit.

While at it, fix the codying style in fbdev.c.

However, if only the TV margins or the connector are changed by a new

next commit affecting these planes.

Let's make sure to add all the planes attached to the connector so that
we can update them properly.

63c381552f drm/armada: Implement fbdev emulation as in-kernel client 
Move code from ad-hoc fbdev callbacks into DRM client functions
and remove the old callbacks. The functions instruct the client
to poll for changed output or restore the display. The DRM core
calls both, the old callbacks and the new client helpers, from
the same places. The new functions perform the same operation as
before, so there's no change in functionality.

Replace all code that initializes or releases fbdev emulation
throughout the driver. Instead initialize the fbdev client by a
single call to armada_fbdev_setup() after armada has registered its
DRM device. As in most drivers, aramda's fbdev emulation now acts
like a regular DRM client.

The fbdev client setup consists of the initial preparation and the
hot-plugging of the display. The latter creates the fbdev device
and sets up the fbdev framebuffer. The setup performs display
hot-plugging once. If no display can be detected, DRM probe helpers
re-run the detection on each hotplug event.

A call to drm_dev_unregister() releases the client automatically.
No further action is required within armada. If the fbdev framebuffer
has been fully set up, struct fb_ops.fb_destroy implements the
release. For partially initialized emulation, the fbdev client
reverts the initial setup.

174c3c38e3 drm/armada: Initialize fbdev DRM client 
Initialize the fbdev client in the fbdev code with empty helper
functions. Also clean up the client. The helpers will later
implement various functionality of the DRM client. No functional
changes.

34c1aeb579 drm/bridge: ti-sn65dsi86: Implement wait_hpd_asserted 
This bridge doesn't actually implement HPD due to it being way too slow
but instead expects the panel driver to wait enough to assume HPD is
asserted. However some panels (such as the generic 'edp-panel') expect
the bridge to deal with the delay and pass maximum delay to the aux
instead.

In order to support such panels, add a dummy implementation of wait
that would just sleep the maximum delay and assume no failure has
happened.
