Patrik Jakobsson 3463cf1aad drm/gma500/psb: Fix cursor gem obj referencing on psb
The internal crtc cursor gem object pointer was never set/updated since
it was required to be set in the first place.

Fixing this will make the pin/unpin count match and prevent cursor
objects from leaking when userspace drops all references to it. Also
make sure we drop the gem obj reference on failure.

This patch only affects Poulsbo chips.

Patrik Jakobsson 22e7c385a8 drm/gma500/cdv: Unpin framebuffer on crtc disable
The framebuffer needs to be unpinned in the crtc->disable callback
because of previous pinning in psb_intel_pipe_set_base(). This will fix
a memory leak where the framebuffer was released but not unpinned
properly. This patch only affects Cedarview.

Old code assumed framebuffer starts at base of stolen memory. Since the
addition of hardware cursors, this might not be true anymore so add the

Dave Airlie f3b2bbdc8a 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
    about being unable to reserve the buffer when plymouth starts,
    this is due to the buffer being in the process of migrating,
    so it makes sense we can't reserve it.

    In order to deal with it, this adds delayed updates for the dirty
    updates, when the bo is unreservable, in the normal console case
    this shouldn't ever happen, its just when plymouth or X is
    pushing the console bo to system memory.

Imre Deak 011c2282c7 drm: prime: fix refcounting on the dmabuf import error path
In commit be8a42ae60 we inroduced a refcount problem, where on the
drm_gem_prime_fd_to_handle() error path we'll call dma_buf_put() for
self imported dma buffers.

Fix this by taking a reference on the dma buffer in the .gem_import
hook instead of assuming the caller had taken one. Besides fixing the
bug this is also more logical.

Dave Airlie 219b47339c 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

Ville Syrjälä c55b6b3da2 drm: Kill user_modes list and the associated ioctls
There is no way to use modes added to the user_modes list. We never
look at the contents of said list in the kernel, and the only operations
userspace can do are attach and detach. So the only "benefit" of this
interface is wasting kernel memory.

Fortunately it seems no real user space application ever used these
ioctls. So just kill them.

Also remove the prototypes for the non-existing drm_mode_addmode_ioctl()
and drm_mode_rmmode_ioctl() functions.

v2: Use drm_noop instead of completely removing the ioctls

Sylwester Nawrocki 5186fc5e8e drm/exynos: add device tree support for fimc ipp driver
This patch adds OF initialization support for the FIMC driver.
The binding documentation can be found at Documentation/devicetree/
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.

Camera input signal polarities are not currently parsed from the
device tree.

Sylwester Nawrocki e5f8683923 drm/exynos: rework fimc clocks handling
The clocks handling is refactored and a "mux" clock handling is
added to account for changes in the clocks driver. After switching
to the common clock framework the sclk_fimc clock is now split
into two clocks: a gate and a mux clock. In order to retain the
exisiting functionality two additional consumer clocks are passed
to the driver from device tree: "mux" and "parent". Then the driver
sets "parent" clock as a parent clock of the "mux" clock. These two
additional clocks are optional, and should go away when there is a
standard way of setting up parent clocks on DT platforms.

Sylwester Nawrocki 4c30cbc0b9 drm/exynos: remove redundant devm_kfree()
There is no need for explicit calls of devm_kfree(), as
the allocated memory will be freed during driver's detach.
Remove the redundant devm_kfree() calls from probe() and
remove() callbacks.

Vikas Sajjan 11963a638f drm/exynos: enable FIMD clocks
Common Clock Framework introduced the need to prepare clocks before
enabling them, otherwise clk_enable() fails. This patch adds clk_prepare_enable
and clk_disable_unprepare() calls to the driver.
This patch also removes clk_disable() from fimd_remove() as it will be done
by pm_runtime_put_sync.
