For consistency with other reference counting APIs in the kernel, add
drm_gem_object_get() and drm_gem_object_put(), as well as an unlocked
variant of the latter, to reference count GEM buffer objects.
Compatibility aliases are added to keep existing code working. To help
speed up the transition, all the instances of the old functions in the
DRM core are already replaced in this commit.
The existing semantic patch for the DRM subsystem-wide conversion is
extended to account for these new helpers.

Backmerge the main pull request to sync up with all the newly landed
drivers. Otherwise we'll have chaos even before 4.12 started in
earnest.

drm/panel: Changes for v4.11-rc1
This set contains a couple of cleanups as well as support for a few more
simple panels.
* tag 'drm/panel/for-4.11-rc1' of git://anongit.freedesktop.org/tegra/linux:
drm/panel: simple: Specify bus width and flags for EDT displays
drm/panel: simple: Add Netron DY E231732
of: Add vendor prefix for Netron DY
drm/panel: simple: Add support for Tianma TM070JDHG30
of: Add vendor prefix for Tianma Micro-electronics
drm/panel: simple: Add support BOE NV101WXMN51
dt-bindings: display: Add BOE NV101WXMN51 panel binding
drm/panel: Constify device node argument to of_drm_find_panel()
Display panels can be oriented many ways, especially in the embedded
world. The rotation property is a way to describe this orientation.
The counter clockwise direction is chosen because that's what fbdev
and drm use.

The big things this time around are:
1) support for hw cursor on newer mdp5 devices (snapdragon 820+,
tested on db820c)
2) dsi encoder cleanup
3) gpu dt bindings cleanup so we can get the gpu nodes merged upstream

compatibility with downstream android dt files.

The original way we determined the gpu version was based on downstream
bindings from android kernel. A cleaner way is to get the version from
the compatible string.
Note that no upstream dtb uses these bindings. But the code still
supports falling back to the legacy bindings (with a warning), so that
we are still compatible with the gpu dt node from android device
kernels.

The plan is to use the OPP bindings. For now, remove the documentation
for qcom,gpu-pwrlevels, and make the driver fall back to a safe low
clock if the node is not present.
Note that no upstream dtb use this node. For now we keep compatibility
with this node to avoid breaking compatibility with downstream android
dt files.
