[RFC v2 0/4] MT8173 DRM support

[Philipp Zabel]

Hi,

this is an update to the May RFC to add MT8173 DRM support. These patches have
a build dependency on two other patches on top of v4.3-rc1:
https://patchwork.kernel.org/patch/6914941 ("iommu: Implement common IOMMU
ops for DMA mapping"), and
https://patchwork.kernel.org/patch/6928621 ("memory: mediatek: Add SMI driver").

The device tree bindings are changed to describe the actual hardware blocks,
a display-subsystem node ties them together. This driver currently supports a
single output stream (OVL0 -> COLOR0 -> AAL -> OD -> RDMA0 -> UFOE -> DSI0)
to a MIPI DSI device.

best regards
Philipp Zabel
