drm/exynos: add iommu support for hdmi driver
Changelog v2:
move iommu support feature to mixer side.
And below is Prathyush's comment.
According to the new IOMMU framework for exynos sysmmus,
the owner of the sysmmu-tv is mixer (which is the actual
device that does DMA) and not hdmi.
The mmu-master in sysmmu-tv node is set as below in exynos5250.dtsi
sysmmu-tv {
-
mmu-master = <&mixer>;
};
Changelog v1:
The iommu will be enabled when hdmi sub driver is probed and
will be disabled when removed.
