Struct of gem object in exynos_drm driver is struct exynos_drm_gem_obj.
It's too long and we can know its meaning of name without _obj postfix.
We use several names to variable name of gem object for exynos_drm -
exynos_gem_obj, gem_obj and obj. Especially "obj" name can cause
misunderstanding with variable name "obj" of struct drm_gem_object.
This will clean about name of gem object for exynos_drm as follows.

The arm_iommu_detach_device() is a function to detach device of iommu
attached by arm_iommu_attach_device(). The exynos-drm uses
arm_iommu_attach_device() so it should use arm_iommu_detach_device() to
detach device of iommu, not iommu_detach_device().
The drm_release_iommu_mapping() is a function to release mapping of

First two cases seems to be unnecessary - register contents will be lost

A bit smaller pull this time. Few minor things, plus initial support
for msm8996 (snapdragon 820).. Sorry, a bit latish, was hoping to get
some 8960/8064 DSI stuff included. But still waiting on the v2 of the
patchset (just pending some minor review comments). It would be nice
to get the DSI patches merged since it would help some folks trying to
get upstream kernel running on n4/n7 and xperia z and wanting to write
some more panel drivers. Also, waiting for OCMEM driver to get merged
via other trees and then I have a small bit to go along with that to
make the gpu actually work on devices w/ OCMEM (snapdragon 800, 805,
etc). So maybe a second later pull req, time permitting.

In order to produce an image, the scalar needs to be fed extra
pixels. These top/bottom/left/right values depend on a various of
factors, including resolution, scaling type, phase step and
initial phase.
Pixel Extension are programmed by hardware in most targets - and
can be overwritten by software. For some targets (e.g.: msm8996),
software *must* program those registers.
In order to ease this computation, let's always use bilinear
filters, which are easier to program from kernel. Eventually,
all of these values will come down from user space for better
quality.
