[PATCH v4 6/9] drm/exynos: fimc: Convert driver to IPP v2 core API
Marek Szyprowski
m.szyprowski at samsung.com
Mon Oct 23 07:54:25 UTC 2017
This patch adapts Exynos DRM FIMC driver to new IPP v2 core API.
The side effect of this conversion is a switch to driver component API
to register properly in the Exynos DRM core.
