Hi Dave,
With this pull request, Exynos drm also supports atomic feature.
However, this doesn't guarantee atomic operation yet so
we will more enhance it later. Besides, it includes new drivers,
MIC and DECON for Exynos5433 SoC, and iommu support and
consolidation to driver initialization.
Ps. this pull request also contains device tree relevant patches.
For this, I got the Acked-by from maintainers - Rob Herring
who is a device tree maintainer and Krzysztof Kozlowski who is
a Exynos SoC maintainer - for each patch so there is no problem
that these patches go to mainline though drm-next.
Summary:
. Add atomic feature support
- Exynos also now supports atomic feature. However, it doesn't
guarantee atomic operation yet, and is required for more cleanups.
This time we just modified for Exynos drm driver to use atomic
interfaces instead of legacy ones. Next time, we will enhance
Exynos drm driver to support the atomic operation.
. Add iommu support
- This is a patch series according to below Exynos iommu integration
work with DT and dma-mapping subsystem,
http://lwn.net/Articles/607626/
. Consolidate Exynos drm driver initialization.
- This patch sereis resolves the issue that only the first compoments
was bound when happened deferred probing for other pipelines and
also makes the driver to be more cleanned up by moving the dispered
codes for registering kms drivers to one place.
. Add new MIC, DECON drivers, and MIPI-DSI support for Exynos5433.
- Add MIC(Mobile image compressor) driver. MIC is a new IP for Exynos5433
and later, which is used to transfer frame data to MIPI-DSI controller
compressing the data to reduce memory bandwidth.
- Add DECON driver for Exynos5433 SoC. This IP is a dislay controller
similar to Exynos7's one but this controller has much different registers
from Exynos7's ones so this driver has been implemented separately.
We will implement a helper modules for FIMD and two DECON controllers
to remove duplicated codes later.
- Add Exynos5433 SoC support to MIPI-DSI driver, and device tree
relevant patches.
Please kindly let me know if there is any problem.
Thanks,
Inki Dae
