drm/exynos: fimd: Make pixel blend mode configurable

2018-12-14T06:46:15+00:00

The fimd hardware supports different blend modes. Add pixel blend mode
property and make it configurable, by modifying the blend equation.

Tested on TRATS2 with Exynos 4412 CPU, on top of linux-next-20181019.

drm/exynos: fimd: Make plane alpha configurable

2018-12-14T06:46:15+00:00

The fimd hardware supports variable plane alpha. Currently planes
are opaque, make this configurable.

drm/exynos: mixer: Fix color range setting

2018-12-05T08:35:21+00:00

Color format and color range was set based on resolution. Change that,
by splitting range and format. Leave color format setting as it is,
set color range based on drm_display_mode using
drm_default_quant_range helper function.

Tested on Odroid-U3 with Exynos 4412 CPU, kernel next-20181128
using modetest.

drm/exynos: mixer: Fix color format setting

2018-12-05T08:34:50+00:00

Fix color format decision based on height(pixels).

According to CEA-861-E:
"High Definition (HD) - A CE video format that, inclusively, has between
720 to 1080 active vertical lines (Vactive) lines per video frame."

drm/exynos/iommu: merge IOMMU and DMA code

2018-12-04T04:23:17+00:00

As DMA code is the only user of IOMMU code both files can be merged.
It allows to remove stub functions, after slight adjustment of
exynos_drm_register_dma. Since IOMMU functions are used locally they
can be marked static.

drm/exynos/iommu: replace preprocessor conditionals with C conditionals

2018-12-04T04:23:17+00:00

Using C conditionals is preferred solution - it provides better code
coverage, makes code more clear.

drm/exynos/iommu: move IOMMU specific stuff into exynos_drm_iommu.c

2018-12-04T04:23:17+00:00

Since __exynos_iommu* functions are used only in exynos_drm_iommu.c we can
move them there.

drm/exynos/iommu: integrate IOMMU/DMA internal API

2018-12-04T04:23:17+00:00

Exynos DRM drivers should work with and without IOMMU. Providing common
API generic to both scenarios should make code cleaner and allow further
code improvements.
The patch removes including of exynos_drm_iommu.h as the file contains
mostly IOMMU specific stuff, instead it exposes exynos_drm_*_dma functions
and puts them into exynos_drm_dma.c.
