90d7116061 drm/vc4: Recognize a more specific compatible string for V3D.
The Raspberry Pi Foundation's firmware updates are shipping device
trees using the old string, so we'll keep recognizing that as this rev
of V3D.  Still, we should use a more specific name in the upstream DT
to clarify which board is being supported, in case we do other revs of
V3D in the future.

0b06e0a794 drm/vc4: Respect GPIO_ACTIVE_LOW on HDMI HPD if set in the devicetree.
The original Raspberry Pi had the GPIO active high, but the later
models are active low.  The DT GPIO bindings allow specifying the
active flag, except that it doesn't get propagated to the gpiodesc, so
you have to handle it yourself.

ca26d28bba drm/vc4: improve throughput by pipelining binning and rendering jobs
The hardware provides us with separate threads for binning and
rendering, and the existing model waits for them both to complete
before submitting the next job.

Splitting the binning and rendering submissions reduces idle time and
gives us approx 20-30% speedup with some x11perf tests such as -line10
and -tilerect1.  Improves openarena performance by 1.01897% +/-
0.247857% (n=16).

Thanks to anholt for suggesting this.

v2: Rebase on the spurious resets fix (change by anholt).

f6e45661f9 dma, mm/pat: Rename dma_*_writecombine() to dma_*_wc()
Rename dma_*_writecombine() to dma_*_wc(), so that the naming
is coherent across the various write-combining APIs. Keep the
old names for compatibility for a while, these can be removed
at a later time. A guard is left to enable backporting of the
rename, and later remove of the old mapping defines seemlessly.

Build tested successfully with allmodconfig.

The following Coccinelle SmPL patch was used for this simple
transformation:

@ rename_dma_alloc_writecombine @
expression dev, size, dma_addr, gfp;
@@

-dma_alloc_writecombine(dev, size, dma_addr, gfp)
+dma_alloc_wc(dev, size, dma_addr, gfp)

@ rename_dma_free_writecombine @
expression dev, size, cpu_addr, dma_addr;
@@

-dma_free_writecombine(dev, size, cpu_addr, dma_addr)
+dma_free_wc(dev, size, cpu_addr, dma_addr)

@ rename_dma_mmap_writecombine @
expression dev, vma, cpu_addr, dma_addr, size;
@@

-dma_mmap_writecombine(dev, vma, cpu_addr, dma_addr, size)
+dma_mmap_wc(dev, vma, cpu_addr, dma_addr, size)

We also keep the old names as compatibility helpers, and
guard against their definition to make backporting easier.

001bdb55d9 drm/vc4: Enable runtime PM.
This may actually get us a feature that the closed driver didn't have:
turning off the GPU in between rendering jobs, while the V3D device is
still opened by the client.

There may be some tuning to be applied here to use autosuspend so that
we don't bounce the device's power so much, but in steady-state
GPU-bound rendering we keep the power on (since we keep multiple jobs
outstanding) and even if we power cycle on every job we can still
manage at least 680 fps.

More importantly, though, runtime PM will allow us to power off the
device to do a GPU reset.

v2: Switch #ifdef to CONFIG_PM not CONFIG_PM_SLEEP (caught by kbuild
    test robot)

This supports 420 and 422 subsampling with 2 or 3 planes, tested with

6674a904d6 drm/vc4: Add a proper short-circut path for legacy cursor updates.
Previously, on every modeset we would allocate new display list
memory, recompute changed planes, write all of them to the new memory,
and pointed scanout at the new list (which will latch approximately at
the next line of scanout).  We let
drm_atomic_helper_wait_for_vblanks() decide whether we needed to wait
for a vblank after a modeset before cleaning up the old state and
letting the next modeset proceed, and on legacy cursor updates we
wouldn't wait.  If you moved the cursor fast enough, we could
potentially wrap around the display list memory area and overwrite the
existing display list while it was still being scanned out, resulting
in the HVS scanning out garbage or just halting.

Instead of making cursor updates wait for scanout to move to the new
display list area (which introduces significant cursor lag in X), we
just rewrite our current display list.

8483d152db drm/vc4: Remove broken attempt at GPU reset using genpd.
I've tested and confirmed that it doesn't actually work.  We'll need
to sort out how to do this properly later, but for now just remove it
since it also caused build breakage due to using CONFIG_PM_SLEEP
functions without our Kconfig depending on PM_SLEEP.

Since your main drm-next pull isn't out of the door yet I figured I might
as well flush out drm-misc instead of delaying for 4.6. It's really just

I've decided to just send this fixes-for-next pull request now, even if
we don't have a patch for the CONFIG_PM_SLEEP build failure reviewed.
If you like my patch for that, I'd be happy to see it applied directly.

This pull request brings in little fixes from Dan Carpenter for the 3D
support added in this -next cycle.

65c4777de5 drm/vc4: copy_to_user() returns the number of bytes remaining
The copy_to/from_user() functions return the number of bytes remaining
to be copied.  We want to return error codes here.

Also it's a bad idea to print an error message if a copy from user fails
because users can use that to spam /var/log/messages which is annoying
so I removed those.

e112e593b2 drm: use dev_name as default unique name in drm_dev_alloc()
The following code pattern exists in some DRM drivers:

    ddev = drm_dev_alloc(&driver, parent_dev);
    drm_dev_set_unique(ddev, dev_name(parent_dev));

(Sometimes dev_name(ddev->dev) is used, which is the same.)

As suggested in
http://lists.freedesktop.org/archives/dri-devel/2015-December/096441.html,
the unique name of a new DRM device can be set as dev_name(parent_dev)
when parent_dev is not NULL (vgem is a special case).

b0b3b79511 drm: Pass 'name' to drm_universal_plane_init()
Done with coccinelle for the most part. It choked on
msm/mdp/mdp5/mdp5_plane.c like so:
"BAD:!!!!!  enum drm_plane_type type;"
No idea how to deal with that, so I just fixed that up
by hand.

Also it thinks '...' is part of the semantic patch, so I put an
'int DOTDOTDOT' placeholder in its place and got rid of it with
sed afterwards.

I didn't convert drm_plane_init() since passing the varargs through
would mean either cpp macros or va_list, and I figured we don't
care about these legacy functions enough to warrant the extra pain.
