drm/cirrus: deal with bo reserve fail in dirty update path
Port over the mgag200 fix to cirrus as it suffers the same issue.
On F19 testing, it was noticed we get a lot of errors in dmesg

this is due to the buffer being in the process of migrating,

In order to deal with it, this adds delayed updates for the dirty

drm: prime: fix refcounting on the dmabuf import error path
In commit
be8a42ae60 we inroduced a refcount problem, where on the

self imported dma buffers.
Fix this by taking a reference on the dma buffer in the .gem_import

drm/prime: keep a reference from the handle to exported dma-buf (v6)
Currently we have a problem with this:
1. i915: create gem object
2. i915: export gem object to prime
3. radeon: import gem object
4. close prime fd
5. radeon: unref object
6. i915: unref object
i915 has an imported object reference in its file priv, that isn't
cleaned up properly until fd close. The reference gets added at step 2,
but at step 6 we don't have enough info to clean it up.
The solution is to take a reference on the dma-buf when we export it,
and drop the reference when the gem handle goes away.
So when we export a dma_buf from a gem object, we keep track of it
with the handle, we take a reference to the dma_buf. When we close
the handle (i.e. userspace is finished with the buffer), we drop
the reference to the dma_buf, and it gets collected.
This patch isn't meant to fix any other problem or bikesheds, and it doesn't
fix any races with other scenarios.
v1.1: move export symbol line back up.
v2: okay I had to do a bit more, as the first patch showed a leak
on one of my tests, that I found using the dma-buf debugfs support,
the problem case is exporting a buffer twice with the same handle,
we'd add another export handle for it unnecessarily, however
we now fail if we try to export the same object with a different gem handle,
however I'm not sure if that is a case I want to support, and I've
gotten the code to WARN_ON if we hit something like that.
v2.1: rebase this patch, write better commit msg.
v3: cleanup error handling, track import vs export in linked list,
these two patches were separate previously, but seem to work better
like this.
v4: danvet is correct, this code is no longer useful, since the buffer
better exist, so remove it.
v5: always take a reference to the dma buf object, import or export.
(Imre Deak contributed this originally)
v6: square the circle, remove import vs export tracking now
that there is no difference

This patch adds OF initialization support for the FIMC driver.

bindings/media/samsung-fimc.txt.
The syscon regmap interface is used to serialize access to the
shared CAMBLK registers from within the V4L2 FIMC-IS and the DRM
FIMC drivers. The DRM driver uses this interface for setting up
the FIFO data link between FIMD and FIMC IP blocks, while the V4L2
one for setting up a data link between the camera ISP and FIMC for
camera capture. The CAMBLK registers are not accessed any more
through a statically mapped IO. Synchronized access to these
registers is required for simultaneous operation of the camera
ISP and the DRM IPP on Exynos4x12.
The driver data and driver_ids static data structures are removed
since Exynos4 is going to be a dt-only platform and there is
currently no board file in mainline that defines platform data
for the FIMC IPP, i.e. uses it.

delay, the vblank interrupt can be enabled in the hardware at that
point, even if the vblank reference count is equal to 0. If a vblank

Accepting the ASLE interrupt without an associated pipe event flag fixes
the issue, the backlight code is called when needed, making the
