Use drm_primary_helper_create_plane() to create our primary plane, and
register the CRTC with drm_crtc_init_with_planes(). This enables the
primary plane to be initialised with the supported format information.

We can do better with armada_drm_crtc_complete_frame_work() - we can
avoid taking the event lock unless a call to drm_send_vblank_event()
is required, and using cmpxchg() and xchg(), we can eliminate the
locking around dcrtc->frame_work entirely.

When the CRTC is in low power mode, it isn't running, and so there's
no point keeping the CRTC clock enabled. Disable the CRTC clock during
DPMS.
We need to re-enable it in the mode_set callback to ensure that the
variant's compute_clock() continues to see its clock in the expected
state (enabled).

Use drm_plane_force_disable() to disable the overlay plane on a mode_set

We're not supposed to store the adjusted mode into crtc->mode. We don't

The ->load_lut() callback is optional, therefore a dummy implementation

Merge tag 'v3.18-rc4' into drm-next
backmerge to get vmwgfx locking changes into next as the
conflict with per-plane locking.
Just a bit of OCD cleanup on headers - this function isn't the core
interface any more but just a helper for drivers who haven't yet
transitioned to universal planes. Put the declaration at the right
spot and sprinkle necessary #includes over all drivers.
Maybe this helps to encourage driver maintainers to do the switch.
v2: Fix #include ordering for tegra, reported by 0-day builder.
v3: Include required headers, reported by Thierry.

A future commit changes the way various vblank calls behave, which

A refcounting leak was found of the original frame buffer attached to
the CRTC when using the page_flip ioctl, resulting in the frame buffer
never being freed.
This was not obvious initially, as if the page flip subsequently
re-attaches the original frame buffer, the refcounts will be balanced.
However, if the original frame buffer is freed, then it will be leaked.
Fix this by ensuring that we take a reference on the incoming fb, but
rely on the queued work to drop that ref count.

Pull DRM updates from Dave Airlie:
"Like all good pull reqs this ends with a revert, so it must mean we
tested it,

This pull is missing nouveau, Ben has been stuck trying to track down
a very longstanding bug that revealed itself due to some other

once he cleans things up. I'm away until Monday so don't want to
delay things, you can make a decision on that when he sends it, I have
my phone so I can ack things just not really merge much.
It has one trivial conflict with your tree in armada_drv.c, and also
the pull request contains some component changes that are already in
your tree, the base tree from Russell went via Greg's tree already,

Loading cursors to the LCD controller's SRAM can be corrupted when the
configured pixel clock is relatively slow. This seems to be caused
when we write back-to-back to the SRAM registers.
There doesn't appear to be any status register we can read to check
when an access has completed.
Inserting a dummy read between the writes appears to fix the problem.

primary plane's fb.

This adds support for the Armada 510 display subsystem found on the
Marvell Dove devices. This IP is re-used across several different Marvell
SoCs with various tweaks, and this driver has been structured to allow
the other IPs to re-use the bulk of this code; further work in this area
is expected from interested parties.
This has been extensively tested on the SolidRun Cubox platform and
appears to work well there.
[airlied: update for api changes merged previous to this]

64x32 resolutions.

This patch adds support for the pair of LCD controllers on the Marvell
Armada 510 SoCs. This driver supports:
- multiple contiguous scanout buffers for video and graphics
- shm backed cacheable buffer objects for X pixmaps for Vivante GPU
acceleration
- dual lcd0 and lcd1 crt operation
- video overlay on each LCD crt via DRM planes
- page flipping of the main scanout buffers
- DRM prime for buffer export/import
This driver is trivial to extend to other Armada SoCs.
Included in this commit is the core driver with no output support; output
support is platform and encoder driver dependent.
