398cbaadec drm/tegra: Enable IOVA API when IOMMU support is enabled
When support for an IOMMU has been enabled, make sure the IOVA helper
code is also activated and the driver can properly manage the IO virtual
address space.

fb80016af0 gpu: Remove depends on RESET_CONTROLLER when not a provider
These GPU drivers only depend on the RESET_CONTROLLER config
option to fix build issues that existed when there weren't stub
reset APIs for reset controller consumers. Given that these
drivers aren't providing any reset controllers themselves, they
don't actually depend on the API to build (just to function) so
they don't need to depend on it. Remove the dependency to fix
recursive build errors like the following:

b110ef3775 drm/tegra: Remove local fbdev emulation Kconfig option
DRM_TEGRA_FBDEV config is currently used to enable/disable legacy fbdev
emulation for the tegra kms driver.

Remove this local config option and use the top level DRM_FBDEV_EMULATION
config option instead.

db4fd5197b drm/tegra: Depend on COMMON_CLK
The introduction of the COMPILE_TEST dependency in commit 158b50aefa
(drm/tegra: Increase compile test coverage) removes the dependency on
COMMON_CLK (implicitly selected via ARCH_TEGRA, ARCH_MULTI_V7 and
ARCH_MULTIPLATFORM).

60c2f709d9 drm/tegra: Make legacy fbdev support optional
A lot of the modern userspace is capable of working without the legacy
fbdev support. kmscon can be used as a replacement for the framebuffer
console, and KMS X drivers create their own framebuffers.

Most people don't have a system where all of this works yet, though, so
leave support enabled by default.

dec727399a drm/tegra: Add DSI support
This commit adds support for both DSI outputs found on Tegra. Only very
minimal functionality is implemented, so advanced features like ganged
mode won't work.

Due to the lack of other test hardware, some sections of the driver are
hardcoded to work with Dalmore.

158b50aefa drm/tegra: Increase compile test coverage
The ARCH_MULTIPLATFORM dependency was introduced back when Tegra didn't
support multiplatform yet as a means to allow the driver to be easily
compile-tested along with other DRM drivers. In the meantime, the new
COMPILE_TEST Kconfig option has been introduced for exactly that
purpose, so use that instead to clarify the intention.

90c37067b7 drm/tegra: Changes for v3.13-rc1
The biggest part of the changes is the decoupling of the host1x and DRM
 drivers followed by the move of Tegra DRM back to drivers/gpu/drm/tegra
 from whence it came. There is a lot of cleanup as well, and the drivers
 can now be properly unloaded and reloaded.
 
 HDMI support for the Tegra114 SoC was contributed by Mikko Perttunen.
 
 gr2d support was extended to Tegra114 and the gr3d driver that has been
 in the works for quite some time finally made it in. All pieces to run
 an OpenGL driver on top of an upstream kernel are now available.
 
 Support for syncpoint bases was added by Arto Merilainen. This is useful
 for synchronizing between command streams from different engines such as
 gr2d and gr3d.
 
 Erik Faye-Lund and Wei Yongjun contributed various small fixes. Thanks!

36c1813bb4 drm/tegra: drop "select DRM_HDMI"
Commit ac24c2204a ("drm/tegra: Use generic
HDMI infoframe helpers") added "select DRM_HDMI" to the DRM_TEGRA
Kconfig entry. But there is no Kconfig symbol named DRM_HDMI. The select
statement for that symbol is a nop. Drop it.

What was needed to use HDMI functionality was to select HDMI (which this
entry already did through depending on DRM) and to include linux/hdmi.h
(which this commit also did).
