SCDC is the Status and Control Data Channel for HDMI. Move the SCDC
helpers into display/ and split the header into files for core and
helpers. Update all affected drivers. No functional changes.
To avoid the proliferation of Kconfig options, SCDC is part of DRM's
support for HDMI. If necessary, a new option could make SCDC an
independent feature.

Replace the DP-helper module with a display-helper module. The
support for DisplayPort becomes an internal option that drivers
have to select. Update all related Kconfig and Makefile rules.
Besides the existing code for DisplayPort, the new module will
contain helpers for other video-output standards, such as HDMI.
Drivers will have to select their required video-output helpers.
Linking all display-related code into a single module avoids the
proliferation of small kernel modules.
The module parameters drm_dp_cec_unregister_delay, dp_aux_i2c_speed_khz,
and dp_aux_i2c_transfer_size are moving from the drm_dp_helper namespace
to drm_display_helper.
v2:
* mention module parameters in commit message (Javier)
* distiguish between display module and DP support in Kconfig
* update Makefile rules for DP helpers
* move Kconfig rules into separate file under display/

Move DisplayPort functions into a separate module to reduce the size
of the KMS helpers. Select DRM_DP_HELPER for all users of the code. To
avoid naming conflicts, rename drm_dp_helper.c to drm_dp.c
This change can help to reduce the size of the kernel binary. Some
numbers from a x86-64 test build:
Before:
drm_kms_helper.ko: 447480 bytes
After:
drm_dp_helper.ko: 216632 bytes
drm_kms_helper.ko: 239424 bytes
For early-boot graphics, generic DRM drivers, such as simpledrm,
require DRM KMS helpers to be built into the kernel. Generic helper
functions for DisplayPort take up a significant portion of DRM KMS
helper library. These functions are not used by generic drivers and
can be loaded as a module.
v3:
* fix include statement in DRM selftests
v2:
* move DP helper code into dp/ (Jani)

Display controller (DC) performs isochronous memory transfers, and thus,
has a requirement for a minimum memory bandwidth that shall be fulfilled,
otherwise framebuffer data can't be fetched fast enough and this results
in a DC's data-FIFO underflow that follows by a visual corruption.
The Memory Controller drivers provide facility for memory bandwidth
management via interconnect API. Let's wire up the interconnect API
support to the DC driver in order to fix the distorted display output
on T30 Ouya, T124 TK1 and other Tegra devices.

Currently configurations can be generated where IOMMU_SUPPORT is
disabled but IOMMU_IOVA is built as a module and DRM_TEGRA as built-in.
In such a case, the symbols guarded by IOMMU_IOVA will not be available
when linking the Tegra DRM driver and cause a linking failure.
Simplify this by unconditionally selecting IOMMU_IOVA, which makes sure
that it will be forced to =y if DRM_TEGRA=y. Technically we can now get
IOMMU_IOVA code built-in even if we don't use it (Tegra DRM only uses it
when IOMMU_SUPPORT is also enabled), but such configuration are of a
mostly academic nature. In all practical configurations we want IOMMU
support anyway.

In order to support CEC the HDMI driver has to inform the CEC driver
whenever the physical address changes. So when the EDID is read the
CEC driver has to be informed and whenever the hotplug detect goes
away.
This is done through the cec-notifier framework.
The link between the HDMI driver and the CEC driver is done through
the hdmi-phandle property in the tegra-cec node in the device tree.

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:

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.

purpose, so use that instead to clarify the intention.

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!

Commit ac24c2204a76e5b42aa103bf963ae0eda1b827f3 ("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).
