Some CRTCs needs mode validation, this patch adds neccessary
callback to Exynos DRM framework. It is called from DRM core
via atomic_check helper for drm_crtc.

It seems this patch is not a drop-in replacement since it causes a
"Division by zero in kernel" error with v4.4-rc2 on an Exynos5800
Peach Pi, causing the display console to not be initialized. X works
correctly though.
An interesting data point is that it only happens when the HDMI
monitor is not plugged on the first mode set, everything works
correctly when booting with a HDMI monitor plugged.
Following is the relevant messages from the kernel log buffer:

Since atomic check is called also for disabled crtcs it should skip
mode checking as it can be uninitialized. The patch fixes it.

This patch was never picked but fixes and important
bug introduced in the v4.4 merge window so it should
be sent during the v4.4-rc cycle.

Mixer driver is selected by CONFIG_DRM_EXYNOS_HDMI option. Since Exynos5433
HDMI does not require Mixer. There will be separate options to select Mixer
and HDMI. Adding new option to defconfig before Kconfig will allow to keep
bisectability.

Latest Exynos SoCs does not have Mixer IP, but they still have HDMI IP.
Their drivers should be configurable separately.

Exynos DRM driver have quite big number of components and options.
The patch re-arranges them into three logical groups:
- CRTCs,
- Encoders and Bridges,
- Sub-drivers.
It should make driver options more clear.

Many Exynos DRM sub-options mentions Exynos DRM in their titles.
It is redundant and can be safely shortened. The patch additionally
makes some entries more descriptive.

I would be happy to see similar for multi_v7. HDMI is already there.
I also wonder why actually DRM_EXYNOS_HDMI has to depend on MIXER or DECON?

Krzysztof

DECON controller has two kinds of data paths in case of Exynos5433 or later.
One is Display path and other is TV path. So it'd be reasonable for DRM_EXYNOS_HDMI to depend on MIXER or DECON -
TV path of DECON controller transfers Display data to HDMI like MIXER IP of previous Exynos SoC did.

So this is not a build-time dependency but rather runtime? What will
happen if HDMI is compiled and enabled (for example in DTB) but there
will be no DECON nor MIXER compiled in?
Best regards,
Krzysztof

Okay, I received the explanation off-line. :)
The solution looks good to me, I'll give the respective tags for
individual patches (please submit also multi_v7).
Best regards,

Mixer driver is selected by CONFIG_DRM_EXYNOS_HDMI option. Since Exynos5433
HDMI does not require Mixer and there are separate options to select Mixer
and HDMI.

+Cc Arnd, Kevin, Kukjin and Olof,
Reviewed-by: Krzysztof Kozlowski <k.kozlowski@samsung.com>
The patch should go with (or before) patchset:
- add atomic_check callback to exynos_crtc
http://www.spinics.net/lists/dri-devel/msg93137.html
to avoid loosing the HDMI support in multi_v7.
Best regards,
Krzysztof
